ABSTRAK

Konkrit merupakan salah satu contoh struktur komposit. Konkrit biasa

memberikan berat badan berat dan kos yang tinggi semasa proses pengeluaran. Oleh itu,

konkrit ringan mempunyai permintaan tinggi dalam pasaran berbanding dengan konkrit

biasa. Konkrit ringan terdiri daripada simen, pasir, bahan pengikat dan air. Penghasilan

konkrit ringan membawa pelepasan gas-gas rumah hijau yang berjumlah besar. Isu alam

sekitar memainkan peranan yang penting dalam pembangunan mampan industri konkrit.

Penggunaan bahan buangan pertanian dalam industri konkrit telah menjadi fokus kajian

atas sebab-sebab ekonomi dan alam sekitar. Dengan menggunakan konsep 4R - Reduce,

Reuse, Recycle dan Replace, hampas tebu akan menggantikan beberapa komposisi

bahan asas dalam konkrit. Dalam usaha untuk menilai kemungkinan penggunaan

hampas tebu dalam konkrit ringan, beberapa ujian seperti ujian mampatan dan analisis

mikrostruktur akan dijalankan untuk menentukan kekuatan, ketumpatan dan keliangan

konkrit hampas tebu.

ABSTRACT

Concrete is one of the examples of composite structure. Typical concrete gives

heavy weight and high cost during production. Hence, lightweight concrete has higher

demand in market compared to typical concrete. Lightweight concrete is made up of

cement, sand, admixture and water. Production of lightweight concrete leads to the

release of significant amount of greenhouse gasses. Environmental issues are playing an

important role in the sustainable development of concrete industry. Utilization of

agricultural waste products in concrete industry has been the focus of research for

economic and environmental reasons. By applying the 4R concept – Reduce, Reuse,

Recycle and Replace, bagasse ash is going to replace some composition of basic

ingredients in concrete. In order to evaluate the possibility of bagasse use in lightweight

concrete, some tests such as compression test and microstructure analysis will be

conducted to determine the strength, density and porosity of bagasse concrete.

CHAPTER 1

INTRODUCTION

1.1 BACKGROUND

A composite is a structural material that consists of two or more combined

constituents that are combined at a macroscopic level and are not soluble in each other.

By applying this technology, the development of light-weight, high-temperature resistant

composite materials will bring evolvement to the next generation of high-performance,

economical composite structure material. Typical composite structure material includes

composite building material such as concrete. Concrete is a construction material which

made up of cement, sand, aggregates and water. However, the manufacturing process of

concrete will produce green-house gasses emissions, which subsequently lead to air

pollution. In view of environmental benefits brought about by widespread usage of

concrete, it is therefore ethically justified to mass produce environmentally friendly

concrete.

Sugar cane represents a major crop especially in tropical region country. Due to

the increasing demand for sugar in the last century, large areas in the tropical countries

all around the world were allotted for sugar cane crops. (Juraimi, 2013). Malaysia

produces a large amount of sugar cane per year. The main product, sugar juice, is

collected and processed for production of sugar while the remaining crushed and

squeezed cane stalk, named bagasse. Bagasse is essentially a waste product that causes

2

additional disposal cost. (Juraimi, 2013). Current research is concerned about the usage

of bagasse in industrial field. Hence, this study aims at using bagasse on composite

concrete.

1.2 PROBLEM STATEMENT

Sugar-cane bagasse is a fibrous waste-product of the sugar refining industry.

This waste-product is already causing serious environmental pollution which calls for

urgent ways of handling the waste (Aigbodion et al., 2010). To solve this issue, there is

some way outs such as reuse the sugar-cane bagasse in certain industries such as

construction industry. Construction industry has a high demand on the usage of concrete.

Concrete is lightweight composite structure material which consists of cements, water,

and aggregates. These are the essential constituent of concrete, leads to the release of

significant amount of carbon dioxide gasses and other greenhouse gas. One ton of

Portland cement clinker production is said to create approximately one ton of carbon

dioxide gas and other greenhouse gases (Naik et al., n.d.).

Environmental issues are playing an important role in the sustainable

development of the concrete industry. Bagasse ash can act as one of the aggregate

replacement. It is partially replaced in the different weight ratio in concrete (Srinivasan ,

2010). This reduces energy use in the kiln and carbon dioxide gas emissions from

calcinations (Naik et al., n.d.). The reuse of post-consumer wastes and industrial

byproducts in concrete is imperative to create an eco-friendly environment.

LITERATURE REVIEW

2.1 HISTORICAL OF CONCRETE

Concrete today is an indispensable part of the fabric of modern society, used for

everything from mundane road pavements and high rise building. However, concrete as

a building material has been around for a very long time. Inventions in reinforced

concrete started in the mid-nineteenth century with Joseph Lambot’s boat as shown in

Figure 2.1 (Neville, 1995). There is another agriculturist who called Joseph Monier has

inspired by Lambot was built a bridge in 1875 at the Château de Chazelet. The bridge is

shown at Figure 2.2. (Neville, 1995). Francois Hennebique, inspired by Monier’s

successes, he initiates the trend of structure building using concrete in Europe.

Nowadays, reinforced concrete became a successful building medium because of

continual improvements in its strength, its economy, its durability, its fire resistance,

and its beauty. Reinforced concrete continues to be improved.

2.2 BASIC INGREDIENTS OF CONCRETE

2.2.1 Cement

Cement is the most common binder which adheres on the surface of a

product to strengthen the structure of product. Cement is the final outcome from

the grinding of clinker in one of the clay types which is marl or mixture of

limestone and clay.

There are two types of cements which commonly in use, one is hydraulic

cements whereas the other one is non-hydraulic cements. Non-hydraulic cements

include such materials like lime and gypsum plasters, which must be kept dry in

order to gain strength. Hydraulic cements are materials that will be harden after

being combined with water, as a result of chemical reactions with the mixing

water and after hardening; it will retain strength and stability even under water.

This strength and stability is that the hydrates formed on immediate reaction with

water and be essentially insoluble in water.

Most construction cements today are hydraulic, and most of these are

based on Portland cement, which is made primarily from limestone, certain clay

minerals, and gypsum in a high temperature process that drives off carbon

dioxide and chemically combines the primary ingredients into new compounds.

However, the choosing alternatives is still depends on the designer’s

recommendations in the project specifications (Abddallah et al. , 2009).

The main types of cement in British standards and those of the American Society for

Testing and Materials (ASTM) are shown in Table 2.1.

Table 2.1 : Types of Cements in ASTM and British Description (Abddallah et al. , 2009)

Characteristic of Cements in ASTM standard:

a) Type I:

It is common cement used in concrete for making pavements, floors, reinforced

concrete buildings, bridges, tanks, pipes, etc.

It is used in concrete not subjected to aggressive exposures, such as sulfate attack

from soil and water, or to an objectionable temperature rise

b) Type II:

It is used where precaution against moderate sulfate attack is important, as in

drainage structures, which may be subjected to a moderate sulfate concentration

from ground waters

It usually generates less heat of hydration at a slower rate than Type I cement and

therefore can be used in mass structures such as large piers, heavy abutments, and

retaining walls

Due to less heat generation it can be preferred in hot weather.

Cements Types

ASTM Description British Description

Type I Ordinary Portland cement

Type II Modified cement

Type III

Rapid hardening Portland

Extra rapid hardening Portland

Ultra high early strength Portland

Type IV Low heat Portland

Type V Sulfate resisting Portland

10

c) Type III:

It is chemically and physically similar to Type I cement, except that its particles

have been ground finer

It provides high early strengths at an early period

It is used when forms need to be removed as soon as possible or when the structure

must be put into service quickly

It is preferred in cold weather for reduction in the curing period

d) Type IV:

It is used where the rate and amount of heat generated from hydration must be

minimized

It develops strength at a slower rate than other cement types

It is most suitably used in massive concrete structures, such as large gravity dams,

where the temperature rise resulting from heat generated during hardening must be

minimized to control the concrete cracking

e) Type V:

It is used only in concrete exposed to severe sulfate action – principally where

soils or ground waters have a high sulfate content

Its high sulfate resistance is due to its low C3A content of about 4%

It is not resistant to acids and other highly corrosive substances

2.2.2 Sand

Sand is a naturally occurring granular material composed of finely divided rock

and mineral particles. It is defined by size, being finer than gravel and coarser than silt.

It is a naturally occurring, finely divided rock. Sand comprises particles, or granules,

ranging in diameter from 0.0625 (or 1⁄16 mm) to 2 millimeters. An individual particle in

this range size is termed a sand grain. The next smaller size class in geology is silt:
