Felixkala Professor and Head, Department of Civil Engineering Dr. M.G.R. Educational and Research Institute University, Chennai, India ABSTRACT 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 concrete which does not shrink and crack. Shrinkage potential of a Self Compacting concrete is perhaps the most important consideration which effects the long – term strength and durability, and hence efforts are being made to reduce the shrinkage and shrinkage 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 plasticiser have the inherent ability to contribute to continued strength development in Self Compacting Concrete. In the present work, concrete made of 7.5% of silica fume, 10% of Fly Ash, 10% ground granulated blast-furnace slag, and 1% of super plasticiser as a replacement of cement was considered. Key words: Granite Powder, Admixtures, Plastic and Dry Shrinkage, Crack and SCC. Cite this Article: M.Manikandan and Dr. T.
