SHRINKAGE AND CRACK DEVELOPMENT OF SELF COMPACTING CONCRETE CONTAINING GRANITE WASTE AS FINE AGGREGATE

Shrinkage is the time-dependant decrease in concrete volume compared with the original placement volume of concrete. Shrinkage results from physical and chemical changes that occur in the paste fraction of concrete. It is difficult to make which does not shrink and crack. Shrinkage potential of a Self Compacting concrete is perhaps the most important consideration which effects the long durability, and hence efforts are being made to reduce the shrinkage and shri cracks. The main objective of this experimental work was to investigate the shrinkage properties of concrete made with granite powder as fine aggregate and partial replacement of cement with combination of admixtures. The granite powder, one of the byproducts in stones crossing process, not being used for any applications other then filling – up low lying areas was identified as replacement material for river sand in concrete. Admixtures such as silica fume, fly ash, slag and super the inherent ability to contribute to continued strength Compacting Concrete.
