Performance of Light Weight Concrete Made With Pumice Stone as Coarse Aggregate with or Without Admixture into the Composition

Abstract

Light weight concrete is introduced rapidly into the construction industry due to wide spread advantage of precast and prestressingelements. It is made up of naturally available light weight aggregates, Pumice is notable one of the most common and the oldest of naturally occurring aggregates utilized lightweight coarse aggregates used for the production of concrete for construction industry. At present investigation, pumice is used as a coarse aggregate at 0, 50 and 100% replacing natural coarse aggregate and study the performance of the light weight concrete with or without admixture in fresh condition and hardened state. Slump and compaction factor values are declining with respect to conventional concrete and strength values are increased with respect to conventional when the composition added with aluminum admixture.
