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.
