Concrete is themostversatile man-made construction material, extensively used for most types of activities in the construction industry worldwide. The initial development of concrete technology revolved around the proportioning of four basic constituents, viz., cements and, crushed granite, and water, which offered little freedom to the designer to impart a desirable attribute to the concrete. This highly complex mixture, which may comprise several binders, admixtures, aggregates of different types and sizes are used in modern construction and are all derived from natural resources. All these materials have been obtained from the existing natural resources and will have distinctiveness for damaging the environment due to their continuous exploitation. Therefore, extensive research is being carried out into the various aspects of this unique material globally.
