A Study on Rheological Behavior of Self Compacted Concrete with Coarse Aggregate of Size Varying from 6 mm and Less than 6mm

Varsha R. Gunagi, H. C. M. Swamy, Dr. G. Prince Arulraj

Abstract: Self Compacting Concrete (SCC) is a self- settling concrete without any vibration. Its important property is flowing on its own weight, requiring no labor for its compaction. Usually the aggregate size used in SCC varies from 10mm to 12.5mm, to accomplish for its flow on itself. The maximum percentage of coarse aggregate used in the SCC is about 50 to 55 percent, so that the remaining amount is mortar matrix, which is responsible for flow property of SCC. Now the problem in SCC is to obtain the desired target strength by using the available concrete mix design procedure. It is proved that in Delhi metro railway project that SCC can be effectively used, better than ordinary, high strength and high performance concrete. In this article we are using coarse aggregate, of size 6/5 mm and make an attempt to check its rheological property (Flow property). The method is compared with standard results and its use in Industry is justified
