Abstract

Self compacting concrete can be described as a high performance material which flows under its own weight without requiring vibrators to achieve consolidation by complete filling of formworks even when access is hindered by narrow gaps between reinforcement bars. Self compacting concrete required a large amount of binder (paste) and chemical admixtures. This paper presents the use of bentonite in self compacting concrete as viscosity modifying agent (VMA). Bentonite as VMA and other chemical admixture which are liquid form of VMA are compared to check the fresh and hardened properties of self compacting concrete such as, Slump flow, funnel, L-box , sieve stability tests, further compressive strength of the self compacting concrete at the age of 28 days was determined.
