®compromise on quality : Soil solidification with GeoCrete

®What is GeoCrete ?

Stabilization of existing or natural soils with cement is a problem because of the humus acids (especially fulvic and carbon acids) that are in organic matter. These

® acids will block the hydration of cement almost completely. Applying GeoCreteas an additive to cement neutralizes the humus acids in such a way that the hydration of cement in the stabilization (or immobilization) is not blocked.

®GeoCrete is an additive to cement and can be mixed together with cement and soils. It has an off – white to grayish color(powder form) which exists of alkaline –

®and alkaline earth elements. GeoCrete and cement together allow an environmental friendly transition of the existing soil into a newly build concrete like structure.

Unlike concrete, in which short crystalline structures are build (that’s why such a construction will crack easily and large surfaces need to be reinforced or the

®cracking controlled), GeoCrete allows long crystalline structures to be build which gives the construction high bearing capacities, elastic modules, the tensile strength. The construction also becomes water impermeable which enhances the frost resistance.

The concept of precast (also known as “prefabricated”) construction includes those buildings where the majority of structural components are standardized and produced in plants in a location away from the building, and then transported to the site for assembly. These components are manufactured by industrial methods based on mass production in order to build a large number of buildings in a short time at low cost.

HOUSING SCENARIO ANDURBANIZATION : INDIA

India is undergoing transition from rural to urbansociety.

Increasing migration from rural to urban areas.

Mismatch between demand and supply of sites and services.

Disparity between high land costs of construction and lower incomes l e a d i n g t o n o n s u s t a i n a b l e situation.

Lack of equitable supply of land, shelter and services at affordable prices.

D e p l e t i o n o f r e s o u r c e s i n construction and negligence of ecology in design.

Lack o f app l icat ion o f cos t e f f e c t i v e n e s s a n d e n e r g y efficiency in construction.

Urban population likely to grow from 360 million in 2010 to 410 million in 2015.

Nearly 36% of India’s population likely to be urbanized by 2025.

Growing urbanization has led to:

a) Pressure on the availability of land and infrastructure

b) Deterioration of housing conditions of the weaker sections of society

c) Increased number of slums and squatter settlements

Rock cutting without blasting technology– Hydraulic Splitters

Hydraulic Splitters Working Procedure

SALIENT FEATURES

Controlled directional cracking. The required direction of the crack can be obtained by just positioning the handle of the splitter in the direction of the required crack.

Much faster and greater output as compared to the conventional Chiseling/Chipping method. As drilling is comparatively easier in Hard rock and the output is directly proportional to the number of holes Drilled.

Noiseless, Environ-friendly and dust free operation.

Single person operation.

Due to smooth splitting operation the remaining structure to be saved will remain intact. Also due to the advantage o f cont ro l c rack direction, we can achieve precise results oriented output.

All splitter are CE MARKED.

GENERAL DESCRIPTIONThe Hydraulic Splitter works on the wedging principle. The wedges of splitter are inserted in pre drilled hole and out of the three wedges the center taper wedge is forced between the two c o u n t e r w e d g e s b y hydraulic pressure forcing them apart. The pressure is transferred to the walls of the Hole (rock/concrete) developing a crack and split further. The important factors a f f e c t i n g S p l i t t e r s p e e d a n d economics are the 'Pre' and 'Post' operat ions l ike Dr i l l ing and s i te cleaning.

DRILLING

T h e p r i m a r y operation while using Hydraulic Splitter is drilling. This is easier by

t h e c o n v e n t i o n a l m e t h o d o f pneumatic drilling with comp-ressor & jack hammer (Drill rod of 800mm length and cross bit Dia. of 48mm).

SPLITTING

After the drilling operat ion the splitter wedges ( t w o c o u n t e r wedges and one center wedge) are inserted in the hole. The control lever sets the f o r w a r d s t r o k e o f t h e w e d g e movement. The hydraulic pressure pushes the center wedge forward forcing the two counter wedges to move outwards, exerting pressure of 415 tons (4045 kn) and split the material. Out the several advantages, the Splitter operation is as fast as 7-8 seconds per s p l i t , r e s u l t i n g i n a c c e l e r a t e d excavation speed.
