Concrete is a composite construction material composed mainly of cement, fine aggregate, coarse aggregate and water. Self compacting concrete (SCC) is an innovative concrete that does not require vibration for placing and compaction. Aggregate occupy 70-75% of the total volume of concrete. From earlier days onwards river sand is used as fine aggregate. Nowadays, M-sand, pit sand etc. are also used. Since pit sand is available only at certain regions and due to the scarcity of river sand and M-sand, it has become necessary to find an alternative material, as fine aggregate. The alternative material selected here is sand from Weathered Crystalline Rock. And this type of rock is abundantly available at low cost in tropical areas. This paper discusses the fresh properties and durability of self compacting concrete using weathered crystalline rock sand as fine aggregate.
