}After analysis, engineers and seismologists recommended

Base isolation, also known as seismic base isolation as the

most effective method to protect the buildings. In this

method the substructure, resting on the ground is

decoupled from its super structure, so that the load for the

structure will distribute to isolation foundation. Steel plates

are used to attach the bearings to the building and its

foundation. When an earthquake hits, it allows the

foundation to move without moving the structure.

}Shock absorber - Many structures easily adopt shock

absorber devices to resist earthquakes. In this, a device

controlling unwanted spring motion reduces the magnitude

of vibratory motions experienced by the building, by

damping the kinetic energy.

}One probable method of dampening the swaying of a tall

building is to build in a large mass that can sway at the top of

the building.

}A structure can easily fail during an

earthquake if the upper storey is

very heavy. In case of such

structures, the roof and upper storey

of the building should be designed

as light as possible.

}Keep minimum balconies and

cantilevers during construction of

the building.

}The shape of the building should be

square or a compact rectangle.

Mr. C. Thiyagu

CTS, Madurai

Major Factors affecting building for Earthquake:

Various types of structural failures are reported throughout

the world. Here we deal with a natural, abstract factor,

earthquake failure and earthquake resistant building

construction. This type of failure happens due to movements

in the earth's layers. The major factors responsible for the

structural failures during an earthquake are as follows:

}Type of Soil

}Shape of Building

}Nature of Design

}Distance from Epicenter

}The Safe Bearing Capacity (SBC) of the soil is an

important determinant of structural failures. Sandy soil is

easily affected by earthquake. This type of soil, which

has high porosity, does not have high load bearing

capacity and is unable to support the foundation of the

building.

}The shape of the building is another important factor

responsible for the failure of the structure. If the building

is irregular shaped and elevated, it may be easily

affected during earthquake.

}Earthquakes happen due to movement of tectonic plates

and are violent on the earth surface. To ensure that a

building is earthquake resistant, the structure should be

strong and ductile enough to survive the shaking with an

acceptable damage, or be equipped with base isolation

or using structural vibration control technologies.

Earthquake resistant construction:

Earthwork resistant building constructions are highly

durable and can withstand all types of failures.

7) Use of round aggregate: For concrete grades up to M 40, the failure pattern is mostly the mortar failure. The round aggregate have the lowest water demand for a given workability. Hence they will either result in lower cement consumption or will give higher strength or result in higher workability. Hence they can certainly be used for making good quality concrete. Hence screened single normally available at site as waste material, if free from shells makes excellent replacement for 10 mm aggregates.

8) Higher size of aggregate: Concrete grades up to 35 where mortar failure is predominant a higher aggregate size will reduce the water demand hence the water cement ratio and will result in better strengths. However, for higher grades where bond failure becomes predominant, a lower maximum size of aggregate will give better results by increasing the area of contact between mortar and metal and reducing the probability of bond failure.

9) Pumpable concrete : Pumpable concrete requires high degree of workability (slump above 100 mm) and high degree of cohesion to prevent segregation. It also requires a higher mortar content to lubricate the pipe line. Higher workability is achieved by increasing the cement content and use of admixtures. Cohesion is achieved by use of higher fines. The fines are increased by increasing sand content or using finer sand or by increasing cement. Hence pumpable concrete always works out more expensive than ordinary concrete. If a concrete is made pumpable, it automatically means that mix is well graded and highly cohesive. However, the water demand of pumpable concrete is much higher. Sometimes there is a risk of inadvertently using higher water/cement ratio to make the concrete pumpable. This will reduce the durability of concrete and due to higher fines content increases the chance of drying shrinkage.

Mr. Bharatesh JakkannavarCTS, Belgaum

Tech Talk

Economical mix design is nothing but optimizing the use of construction materials particularly the material required for making of RCC/PCC keeping in mind the characteristic of the concrete like strength required and project requirements. We also need to take into consideration weather conditions, maximum size of aggregate and minimum cement content.

Cement content can be reduced by selecting appropriate raw materials and their volume proportion in such a manner that the total surface area of the aggregate mass should be as low as possible and ratio of aggregate to cement should be in the ratio 3.6 to 4.0.

1) Use of graded sand with low silt content.

2) Aggregate should be equi-dimensional with minimum flakiness and elongation.

3) By using higher size of aggregates where cover and reinforcement spacing permit.

4) By reducing the workability requirement of concrete - higher workability always comes at a cost and is achieved by increasing the cement content or by adding plasticizers.

5) By using pozzolonic materials like fly ash & ground granulated blast furnace slag etc. These materials not only bring economy but also increase the workability as well as durability of concrete.

6) By correct use of compatible admixture. If admixtures are used judiciously after testing compatibility with cement, they substantially reduce the cement content. This is more so for higher grade of concrete and where higher workability is desired. The cost incurred on admixture in such cases is less than that required for additional cement.

Sulphur Polymer Cement Concrete

Mix proportion is - Aggregate (fine & coarse) - 83.0 %

Mineral filler - 4.9 %

Sulphur - 11.0%

STX (polymer additive) - 1.1 %

Sulphur polymer cement concrete can be produced by using sulphur polymer cement. This sulphur polymer cement is polymer added cement. While we produce this concrete, hydrocarbon reacts with the sulphur which stabilizes sulphur and convert into “micro crystalline” form which gives good strength to concrete. This sulphur polymer additive has high value in sulphur polymer cement concrete production.

By using this cement we can produce both types of concrete viz. cast in situ as well as precast too. Like- construction of floor & wall, sump basin, tank foundation etc.

Moreover this concrete is very useful in chemical industrial process application like- leach tank, pipeline through chemical pass, acid loading area, chemical storage tank etc.

While we use this cement (sulphur polymer cement) in concrete, cement should be cost competitive, acid resistant, high strength and curing should not be required for more than 24 hours.

This type of concrete is produced in asphalt modified plant by heating and drying method. During the process sulphur is heated upto its melting point & then mineral filler & additive STX are added.

For reinforced concrete, glass fibers are used which increases the strength of concrete. Use of alkali resistant fiber is restricted, because it produces corrosive effect.

Need For Concrete Cover

Concrete in the cover region protects steel reinforcement in two

ways.

► By providing a dense, strong and impermeable barrier

against ingress of moisture, oxygen, chlorides, sulphates,

carbon dioxide and other aggressive gases and chemicals.

► By providing a passive protective coating on steel surface.

Due to alkaline nature of concrete this coating prevents

corrosion of steel.

This protection remains effective as long as concrete is strongly

alkaline in the cover region. This protection remains for a longer

duration of high strength and low water cement ratios.

Carbon dioxide, along with moisture and oxygen in the

atmosphere form carbonic acid which attacks the concrete

surface and causes carbonation resulting in drop in alkalinity of

concrete at the surface. This carbonation process continues

further and penetrates into the concrete. The depth of

penetration of carbonated concrete will mainly depend on the

grade (strength) of concrete. Once this depth of carbonation

goes beyond the concrete cover the protection offered by

concrete to reinforcement steel considerably reduces resulting

in commencement of corrosion.

Quality of Cover Devices/Spacers

It is often observed that cover devices specially made out of

cement mortar or concrete, in our country, are of extremely poor

quality. They are most often manufactured at site. Hand mixed

mortar is hand compacted without any control over W/C or

without assuring the correct grade of concrete. Cover blocks

are also not fully compacted and adequately cured. As a result

of this, cover devices are porous and full of voids and easily

allow moisture and other chemicals to attack the steel to which

they are generally fixed. The cover devices should be such that

they have the same strength and W/C as that of main concrete

member. They should be dense. They should be strong enough

to take the load which gets transferred on them during

concreting and should be of correct size so as to maintain the

reinforcement steel away from the exposed surfaces of

concrete.

Quality of concrete in the cover is very vital as aggressive

chemicals and moisture can cause serious loss of durability of

concrete. Besides thickness grade, W/C ratio, cement content

of concrete in the cover region will greatly influence the

durability of concrete. However, batching, mixing, transporting,

placing, compaction and curing of concrete while it is produced

also hold a key to durability of concrete cover. All these steps

will have to be executed with great care and supervision to

avoid porosity of any type. It is also important to determine

whether or not concrete cover of greater thickness can be used

as they can have serious negative effects on the concrete in the

cover region due to crack formation, thereby resulting in

corrosion or other problems of concrete deterioration. The

cover devices used in concrete needs very serious looks as

their poor quality often create passages for moisture and

chemical ingress instead of protecting the reinforcement steel

to which it is supposed to provide protective cover of dense

concrete.

Mr. Rameshwar Singh

CTS, Patna

Cover to Reinforced Concrete

Cover to reinforced concrete member is the minimum thickness

of concrete provided over the reinforcement steel measured

from the exposed concrete surface to the closest reinforced

steel surface. Concrete is required to cover and protect

reinforcement steel within its body. The concrete cover is often

subjected to impact, wear and ingress of moisture along with

other chemicals. The cover should therefore be strong, wear

resistant, dense and having low permeability. Concrete in the

cover region plays a very important role in durability of the

structure. The role of concrete in the cover region can be more

or less compared to the role human skin plays in protecting the

flesh and other parts of the body.

Requirements of Concrete Cover

► To achieve good durability it is very much important to have

the following requirements for concrete in the cover region

► The concrete should be free from macro defects like

honeycombs, entrapped air, crack, void broken edges etc

► The concrete should be strong and durable (low water to

cement ratio)

► Concrete should be dense and free from micro defects

► Concrete should be wear resistant

Ar. Shiv Datt Sharma is a renowned figure in the field of architecture with a rich repertoire of work. He heads the firm, M/s S.D. Sharma & Associates in Chandigarh. He has worked with renowned Architects like Le Corbusier, Pierre Jeanneret, Maxwell Fry and Jane B.Drew and Mr. M.N. Sharma (First Indian Chief Architect of Chandigarh).

He has worked on some very prestigious projects including activities for Indian Space Research Organisation, Institute of Microbial Technology (Chandigarh), Sanjay Gandhi Postgraduate Institute of Medical Sciences (Lucknow) and many others. He has numerous awards to his name including the 'Babu Rao Mhatre Gold Medal 2001' for lifetime contribution in the field of architecture, “Commendation Award” for Best

Institutional Building” (National Institute of Plant Genome Research”-2009 by Archi Design and the Great Masters Award at Architect of the Year Awards, 2014 and several others. His works have been published in various magazines over the years and he has served as a member of Council of Architecture, Indian Institute of Designers and International Panel by Govt. of Nigeria.

The Visionary Speaks In conversation with Ar. Shiv Datt Sharma

Q1) Please throw some light on the early days of your career. Why did you choose architecture as a profession and what challenges did you face in the early phase of your career?

The decision to choose architecture as a profession was in line with my liking for order and geometry, which have been my favourites right from school days. I have been raised in villages and have been used to even the illiterate women having excellent natural aesthetic instinct. They paint rangolis, impressions of hands on the walls, etc., to keep their houses aesthetically rich and orderly. Every house, also has a Tulsi plant and another larger tree to build a pleasing environment.

Getting the opportunity to work on the Chandigarh project was a challenge. But it also came with its rewards, as we got to rub shoulders with the topmost architects.

Working in Chandigarh, I was fortunate to learn “lasting lessons from the legends” as I was in the company of the greatest architects of the era, like Le Corbusier and

Pierre Jeanneret. It was also a great opportunity for me to gather fascinating facts about Le Corbusier, the person, the architect, the thinker, the writer and the painter. The Chandigarh office was, to us, more like an institute where we were being educated in various aspects of architecture and town planning.

Modern movement was started by prominent architects of the west under the leadership of Le Corbusier. He subsequently came to India to design the city of Chandigarh and to reinforce modernism and its adoption.

I have been pursuing modernism and its philosophy all my life and I found it very apt for the contemporary society considering their lifestyle and aspirations. Modernism followed the 'Spirit of the Time' and its emphasis was to enrich human life. It is believed that if architecture does not enrich human life, it has no reason to exist.

Q2) Since you have worked with renowned international architects, what is the perception of Indian architecture in foreign countries?

Corbusier and Pierre Jeanneret. Architecture is a natural and honest expression of pure thoughts, with no superficialities. Glorifying brick and cement as versatile materials to depict architectural expression, much like painting and sculpture, for a very noble-aesthetic reasons.

The only source of inspiration is Le Corbusier and Pierre Jeanneret with whom I had the opportunity to work with and learn the fundamentals of architecture from, during my formative years and both have left an indelible mark.

Global exposure has created lot of confusion in the minds of the present generation and human life itself. I believe that if one has their priorities sorted, the vast exposure to information and techniques one gets today, can be better channelized.

Architect of the Year Awards (AYA) is a great motivational platform for the Architects of today to perform even better. By recognizing outstanding work in the field of architecture, it also acts as benchmark by which an individual can self-evaluate and enthuse themselves. I wish their selfless efforts towards this great cause continue to bring laurels to the Architect fraternity in the years to come.

Q5) What/Who is the inspiration behind your designs?

Q6) What is your view about the work of architects of today's generation?

Q7) What is your opinion about J.K. Cement's contribution towards instituting the Architect of the year Awards (AYA)?

Yes, I was lucky to work with the internationally renowned architects who had very high opinion of Indian architecture and Indian civilization.

Environment friendly construction, Green architecture and sustainability etc. are the new challenges being faced by the world, and architects have their equal responsibility to find adequate and appropriate solutions to these challenges.

Green Architecture is an approach to avoid harmful effects on human health while attempting to rescue damages done to the environment - attempts are being made to safeguard air, water and energy.

Environment friendly buildings need to be built using technology, materials, energy saving systems which do not burden future generations. It is not just through architecture, but also the production of various environment friendly construction materials that sustainable development can be attained.

Having learnt valuable lessons from the legends during my formative years at Chandigarh, I value the importance of purity, simplicity and harmony, the use of crystalline geometry, use of material in its original form, a spirit of minimalism and a hunger for perfection.

My work has been an extension of the philosophy of Modernism and hybrid thinking professed by Le

Q3) What is your take on environment friendly construction/ green architecture?

Q4) If you have to define a set of values that are crucial to you as an architect, what would that be?

We are aware that many waste materials are produced

during construction and demolition of a building or a project.

Construction waste consists of unwanted materials

produced directly or indirectly by the construction work. This

includes building material such as concrete and bricks,

asphalt, metals, timber, insulation, nails, electric wiring, PVC

as well as waste originating from site preparation such as

dredging materials tree stumps and rubber. Most

old brick broken block and other masonry rubble which can

be buried on site during foundation back filling. Good quality

used concrete can also be used as brick or block for land

scarping walls and foundation for small building and in

construction of garden wall, Floor tiles can be made from

crushed debris. PVC can be used recycled six to seven

times with a product life of 100 years. Trash bags and plastic

sheet can be recycled through ecology action. Branches and

trees from brush clearing can be stored separately and

chipped at the city's land fill facility, or chipper can be used on

site create land scarping.

Thus due to reuse or recycling of construction and demolish

waste material, one can save environment from being

polluted and it also helps in cutting and saving.

Use of Waste Materials in Building Construction

construction waste goes into land filling, increasing the

burden on landfill. Loading and operation also causes soil

pollution, so it is necessary to reuse or recycle these

materials. Construction waste recycling is the separation

and recycling of recoverable waste materials generated

during construction and remoulding. Hence, some materials

can be recycled directly into some product for reuse, others

can be reconstituted into other usable products. In the

process of reuse of this material, the most important step is

on-site separation. First we have to clean concrete chunks,

This reduces the chance porosity due to entrapped air and

honeycombing. All the steps of concrete making must be

properly supervised and controlled. Each step has significant

role to play in durability and therefore cannot be ignored.

There are several reasons due to which concrete cracks. Its

not possible to completely avoid cracking. Proper design &

selection of materials including the chemical admixture,

curing, protection against wind, low humidity and ambient

temperature are necessary to reduce cracking.

Mr. Pawan Pandey

CTS, Ahmedabad

Concrete is a very durable material but at the same time

concrete structures have shown poor durability and lose

strength within a few years of their service life. To achieve

good durability of concrete, the following factors should be

properly controlled.

�Structural design

�Study of environment in which the structure in being

constructed. Temperature. humidity and chemical

condition to be examined

�Selection of all materials of concrete and good concrete

mix design

�Concrete specification such as maximum water to

cement ratio, maximum cement content, type of cement

and grade of concrete

�Quality of concrete cover around the steel reinforcement

�Workability and cohesiveness of concrete mix

�Batching, Mixing, Transportation. Placing, Compacting

and most important Curing of Concrete

�Maintenance and usage in service life

It is very important to control Water/Cement ratio while

designing and producing concrete mixes. Low water &

cement ratio give low permeability of water and other

aggressive chemical. It also means high strength.

Concrete must have good workability and cohesiveness.

Ferrocement

Ferrocement is a relatively new material consisting of wire

meshes & cement mortar. This material was developed by

P.L. Nervi, an Italian Architect & Engineer, in 1940. It consists

of closely spaced wire meshes which are impregnated with

rich cement mortar mix. The wire mesh is usually of 0.5 to 1.0

mm dia. Wire at 5mm to 10mm spacing & cement mortar is of

cement sand ratio of 1:2 or 1:3 with water/cement ratio of 0.4

to 0.45.The reinforcement elements are usually of the order

of 2 to 3 cm in thickness with 2 to 3 mm external cover to the

reinforcement. The steel content varies between 300 kg to

500 kg/cu meter of mortar. The basic idea behind this material

is that concrete can undergo large strains in the

neighborhood of the reinforcement & the magnitude of strains

depends on the distribution & subdivision of reinforcement

throughout the mass of concrete.

Ferrocement is widely accepted in U.K, New Zealand & U.S

as a boat building material. It has also found various other

interesting civil engineering applications. The main

advantages are simplicity of its construction, lesser dead

weight of the elements due to their small thickness, its high

tensile strength, less crack widths compared to conventional

concrete, easy repairability, noncorrosive nature & easier mould

ability to any required shape. There is also saving in basic

materials namely cement & steel. This material is more suitable

for special structures like shells which have strength through

forms & structures like roofs, silos, water tanks & pipelines.

The material is under active research in various countries &

attempts are being made to give a sound theoretical backing to

establish the material behaviour. This is a highly suitable

material for pre cast products, because of its easy adaptability to

prefabrication & lesser dead weight of the units cast. The

development of Ferrocement depends on suitable casting

techniques for the required shape. Development of proper

prefabrication techniques for Ferrocement is still not a widely

explored area and the gap needs to be filled.

In cement there should be 'optimum sulphate content' or

'optimum gypsum content'. Sulphate present in cement, both

in the clinker sulphate and added gypsum retards the

hydration of aluminate phase. If sulphate is insufficient in the

cement a flash set occurs and excess of sulphate in cement

causes false setting.

Therefore a balance is always required between the ability of

the main clinker minerals (aluminate phase) to react with

Sulphate and the ability of the cement to supply sulphate.

Generally the aluminate phase reacts with sulphates in the

early stages after mixing. The optimum sulphate content is

affected by many factors, which includes aluminate content,

aluminate crystal size, aluminate reactivity, solubilities of the

different sources of sulphate.

Apart from the compositional parameters, physical

parameters are also important, particularly surface area of

the cement and the particle size distribution. The fineness of

the cement affects the rate at which the cement hydrates.

More fine cement will result in a faster reaction.

Mr. Neelanjan Bhattacharjee

The strength of concrete is the process of hardening and this

process may continue for weeks or months after the concrete

has been mixed and placed. Hardening is due to the

formation of calcium silicate hydrate as the cement continues

to hydrate.

There are many relevant factors which affect the strength of

concrete, some of the important ones as follows:

Concrete Porosity : The concrete is full of voids, voids are

filled with air or with water. Air voids are easily visible and

these voids create pores in concrete, the more the pores in

the concrete the weaker it will be. The main source of porosity

in the concrete is the ratio of water to cement in the mix,

known as the 'water to cement' ratio.

The water to cement ratio is defined as the mass of water

divided by the mass of cement in a mix. The recommended

'water to cement' ratio for a mix should be approximately 0.4,

because in the mix having 'water to cement ' ratio of 0.4 all

the cement reacts with water to form cement hydration

product no excess water remains.

Whereas in case of higher 'water to cement' ratio mix the

excess water remaining after cement hydration fills the pore

space with water and when the concrete dries out, the pores

are left behind.

This creates pores in the concrete. As the porosity increases,

the compressive strength of the concrete will decrease.

Factors Affecting the Concrete Strength

Soundness of aggregate : If the aggregate which are used

in the concrete mix are weak, the concrete formed will also be

weak. Examples of weak aggregates are Rocks with low

intrinsic strength, such as chalk, are clearly unsuitable for use

as aggregate.

Aggregate- paste bond: The bond between the paste and

the aggregate is very important. If there is no bond, the

aggregate effectively represents a void and voids are the

source of weakness in the concrete.

Cement related parameters : The composition of the

individual cement minerals and their proportions in the

cement can affect the rate of strength growth and the final

strength achieved.

Since alite is the most reactive cement mineral that

contributes significantly to concrete strength, more alite

should give better early strengths ( early means up to 7 days).

During the manufacturing process of cement, it is possible

that lighter burning of a particular clinker could result in higher

early strength due to the formation of more reactive alite.

T.M.T. bars

The requirement today is low cost deformed bars with

guaranteed minimum 500N/mm2 yield strength and having

adequate ductility. Such rebars are required to be used in high

seismic zones as about 60% of land in India falls under high

seismic zones III, IV & V. In mid eighties two rapid water

quenching technologies known as THERMEX and TEMCOR

were developed. These technologies both adopt online

quenching and self tempering of steel, with a guarantee for

elongation of well above 16% in Fe500 and Fe550 grade steel.

The quenching and self tempering process “Thermo

mechanical treatment “is not a substitute for C.T.D. Fe 415

grade bars in facts they have superior qualities making them

more suitable for reinforced concrete structures .

High strength rebars using micro alloys

High strength rolled rebars of high strength using micro alloys

such as Niobium(Nb), Vanadium (V), and Titanium (Ti) in

various proportions were also developed and used in various

countries but these bars have limited usages due to the use of

costly micro alloys in their production.

Commonly T.M.T. bars produced by adopting quenching and

tempering technology are far superior for high performance

RCC structures.

Mr. Pradeep Kumar Barik CTS, Bhubaneswar

Steel Reinforcement - Technological Innovations

After Second World War, several technological innovations took

place in the reinforcement industry. Bars with high tensile

strength, corrosion resistance, and better bond strength with

concrete were demanded by civil engineers. It was realized that

not only high compressive strength concrete but also higher

grade steel with optimum bond and durability were necessary for

structural application in order to achieve maximum benefits. The

requirement was steel which could withstand close bends without

exhibiting surface cracks as also easy weldability at necessary

laps and locations. When high strength steel and high strength

concrete are used in combination, significant reduction in the size

of RCC member has been observed, irrespective of the method

used in the design of the structure i.e. working stress or Limit

state. Hence conservation of raw materials for production of high

strength, durable reinforced concrete contributes to better

sustainability and economy.

Development Scenario

After 1960, new types of rebars with varying degrees of

acceptability were introduced.

► Mild steel ribbed bars for better bond with concrete

► High strength deformed bars (H.S.D. bars)

► Cold twisted deformed bars (C.T.D.bars)

► Thermo processed rebars - Commonly known as T.M.T bars

► Ribbed bars from steel with alloying elements for lighter yield

and tensile strength

► Ribbed bars with corrosion resistance through addition of Cr

and Cu. In the steel used thermo processed rebars

► Stainless steel bars

Mild steel ribbed bars

For preventing slip and improving the mechanical bonding

between steel rebars and cement concrete ,mild steel ribbed bars

were developed. Both plain and ribbed bars had very ductility as

indicated by the elongation value. No specific pattern of

transverse ribs was prescribed. How ever all standard s specified

only the bond strength values and testing procedure.

High Strength Deformed bars

Introduction of H.S.D. bars and development of high strength

cement concrete have taken place simultaneously. The thrust

was on reduction in quantity of steel used in RCC due to these

developments .The immediate short term objective was steel

bars having 400N/mm2 strength with adequate ductility and with

a further goal of 500 N/mm2 strength steel with adequate ductility.

Cold Twisted Deformed Bars

The primary objective was reduction of the quantity of steel used

in RCC structures through the use of C.T.D. bars. So this bar was

developed. These rebars were generally accepted in the yield

strength range of around 400 N/mm2 with elongation of 14-

15%. Higher strength C.T.D bars was not accepted by the

engineers, since elongation values dropped to around 12%

while the strength increased. This type of bars had other

drawbacks namely surface stress and visible cracks due to

cold twisting which led to higher corrosion rate and durability

problems.

Civil Engineering & Architecture Students' Awareness ProgrammeLectures & exhibitions are conducted for Civil Engineering students on cement, its applications & technical problems encountered in construction to enable them to appreciate field situation. Similar lectures and exhibitions are also organized for students of Architecture emphasizing on special skills needed to do such architectural jobs which would be beneficial in their work later.

Curing And Its Methods

Curing is used in reference to the maintenance of a favourable environment for the continuation of chemical reactions i.e., retention of moisture within or supplying moisture to the concrete and protecting against extreme of temperature.

Curing has a strong influence on various properties of concrete and therefore it should not be taken lightly. Strength durability, water tightness, wear resistance, volume stability, chemical attack, and resistance to freeze-thaw cycle are much superior of a well cured concrete or mortar than that of a concrete wherein curing was neglected. Let's understand the process of curing as,

Water in the capillaries should be prevented from evaporating and for this it is necessary to maintain an environment of high humidity around the freshly placed concrete or mortar till it attains reasonably good strength. This process is called Curing of Concrete.

The chemical action between cement and water which results in the setting and hardening of concrete or mortar, is dependent on the presence of water .It is important to ensure that the water is either retained to enable the chemical action to be continued till such time the required strength is gained.

Loss of water due to evaporation from the concrete or mortar surface may result in slowing down or stopping the hydration process and resulting in reduction of strength and durability.

Curing should start immediately after the compaction and finishing operations on the concrete have been completed. IS 456-200 advises to keep concrete constantly wet for at least 07 days from the date of placing concrete in case of OPC and at least 10 days where mineral admixture or blended cements are used. The period shall not be less than 10 days for concrete exposed to dry and hot weather conditions and 14 days when blended cements or mineral admixtures are used.

Retaining moisture within the concrete may be sufficient for low to moderate cement content (Blended Cement) but for mix rich in cement (OPC) generates considerable amount of heat and for this concrete water curing should begin as soon as possible and more curing frequency to replace any lost moisture and to dissipate heat, otherwise it leads to shrinkage cracks.

OBJECTIVE OF CURING

• To prevent early drying

• To develop a uniform and steady strength over a period of time

• To lessen shrinkage

• To control thermal cracks and creep

TYPES OF CURING

1 Ponding or immersion in water

The best curing method is total immersion of concrete in water and also note that Ponding water lost due to evaporation should be filled.

2. Fogging or spraying water

This method can be applied to both horizontal and vertical concrete/mortar surfaces. Ample water is necessary throughout the curing period and covering the surface with gunny bags. May help in retaining the water.

3. Moist fabric covers

Fabric coverings saturated with water, such as hessian, cotton mats rugs or other moisture retaining fabrics are commonly used for curing and this method is not observed.

4. Plastic sheet

Plastic sheets made from polyethylene film comes under the category of effective moisture barriers and can be used on horizontal, vertical, surfaces as well as on surfaces of different shapes and sizes.

5. Curing Compounds

Curing compounds consists of waxes, resins, chlorinate rubber and solvents of high volatility and form a thin liquid membrane on the concrete surfaces and result in preventing to a certain extent evaporation losses.

The curing compounds are generally two types as clear or translucent and white pigmented.

100 mm thick concrete overlay with joint spacing ranging from

Whitetopping : Cost Effective Concrete Overlay on Bituminous Roads

Concrete is a very durable material for the construction of roads

and highways. Several highways, expressway and city roads

have been constructed with cement concrete in the recent past in

India. Cement concrete roads offer many advantages like long

life of more than 30 years, minimum maintenance requirement

and 10-15 % fuel saving for heavy vehicles. Cement concrete has

been used for the construction of new roads, highways and also

for the rehabilitation of existing distressed bituminous

pavements. Whitetopping involves placing a concrete overlay on

a distressed bituminous pavement. Depending upon the traffic,

axle loads of the vehicles and thickness of the overlay,

whitetopping is often categorized as Ultrathin Whitetopping

(UTWT), Thin Whitetopping (TWT) and Conventional

Whitetopping (CWT). UTWT typically involves placing 50 mm to

Tech Talk

100 mm to 200 mm thick with the same joint spacing of 1.0 m to

1.8 m or slightly larger spacing. Conventional whitetopping is

more than 200 mm thick with the joint spacing and slab size

(3.5 m x 4.5 m) similar to concrete pavement. Milling of the top

distressed surface of the existing bituminous surface is

desirable in case of ultrathin whitetopping. Milling not only

removes the top deteriorated part pf the bituminous layer but it

also produces a rough surface which can develop some kind of

bonding between the existing milled bituminous surface and

concrete overlay. The bonding helps ultrathin concrete overlay

to sustain traffic for a longer period. In the recent past many

projects of whitetopping have been completed on city and

colony roads either with milling or even without milling.

A basic guide to some important and more common factors

that can lead to colour variation in the production of concrete

and concrete products.

Raw materials:- Careful selection of raw materials is

paramount in the production of concrete and concrete

products. Consistency of the material is the predominant key

when selecting and using raw materials.

(a) Pigments: Pigment oxides should be chosen that are

reliable in quality and consistency. They should be free

from lumps, excessive moisture or foreign matter .They

should be readily wetted by water to allow quick and

complete dispersion. They should be alkali stable,

resistant to UV light, insoluble in water, weather resistant

and durable. Carbon black and organic dyes are not

generally recommended as suitable for use in cement

products

(b) Cement: The cement, cement blends and blending

materials such as fly ash should be chosen to give the

degree of colour consistency required for the specific

application. In general ,off white and white cement have

a higher degree of colour uniformity although choice may

be restricted to grey cement type due to the final colour

being sought, the availability of materials and of course

commercial restriction.

Tech Talk

24

Technical Information: Source of Colour Variation

(c) Water: Water used in the production of concrete and

concrete products should be clean and if recycled free

from particles that may lead to the discolouration of

finished product. Water pH should ideally be neutral or

slightly alkaline due to the highly alkaline environment

into which it will be added.

(d) Aggregates: The effect of variation in aggregate colour

is less influential in colour of concrete product than other

factors, it may be very important in polished, honed and

exposed aggregate finishes. The colouring effects of

aggregates may not be immediately apparent in some

applications and their effect may need to be considered

in service as they are exposed to wear or weathering.

The influence of aggregate and sand colour may be

more noticeable in pale coloured concrete made off

white or White Cement rather than with Grey Cement.

(e) Sand: The effect of sand may be more influential than

aggregates due to relatively small particle size of the

material. It may contain significant quantities of clay and

fine silt particles of size less than 75 microns as these

may have a strong pigmenting effect on the concrete. It

has significant effect on the surface of the concrete and

concrete product including staining or pitting. Clay and

organic materials are also relatively weak and can form

perfect defect and capillaries that allow the ingress of

water into the concrete.
