Abstract :
In reviewing technology advances through the centuries, it is evident that material development plays a key role. Considerable efforts are still being made in every part of the world to develop new construction materials. In the construction industry, concrete technology is heading towards entirely new era by way of using polymers and fibres along with Super plasticizer in concrete. Increasing interest is being shown in the area of new materials in the past decade. This is quite understandable because, it is slowly, but increasingly being recognized that economic progress in construction depends more on an intelligent use of the materials and constant improvement of available materials than on extreme refinements of structural analysis.
Concrete is probably the most widely used material in the world in view of its strength, structural stability, durability, economic considerations and low level maintenance and Portland cement, probably the most important constituent of concrete, is a versatile and relatively low cost material. With the extensive use of cement for widely varying conditions, technologists catered to the needs of the construction industries for specific purposes. Some of the admixtures presently being used include pozzolanas, retarders, accelerators etc. Concrete is usually characterized by its compressive strength. It has been observed that microstructure is very important for the macro performance. The versatility of concrete as a building material pushed the research into improving rather old material, the demand for taller reinforced concrete structures which increase the quest for higher concrete strength.
