Abstract :
Self-compacting concrete (SCC) is a flowing concrete mixture that consolidates under its own weight. The highly fluid nature of SCC makes it suitable for placing in difficult conditions and in sections with congested reinforcement. Properties of coarse aggregates is one of these factors that has a significant influence on behaviour of SCC. In this study, two SCC mixes have been designed using two kind of aggregates. It was found that the rheological tests conducted on fresh SCC such as slump flow, L-box, U-box and V-funnel are sufficient to ascertain SCC attributes. Compressive strength of the mixes were tested after water curing for 28 days. Comparative study on performance of SCC mixes with the two different types of coarse aggregates is also made.
