Experimental Investigation on Mechanical Properties of Light Weight Concrete Using Leca

T. Sonia | R. Subashini | R. Banupriya


Abstract: This study examined the structural behaviour of Lightweight concrete (LWAC) using lightweight aggregates (Light expanded clay aggregates LECA) and normal weight aggregates, aims to investigate on concrete mix M25 by the effect of partially and fully replacement of the coarse aggregate by Leca with various percentage such as 20 %, 40 %, 60 %, 80 % and 100 % and fly ash percentage such as 15 %, 20 %, 25 % used as partial replacement for cement in concrete. Analysis of this concrete was done in fresh state as well in hardened state to evaluate physical and mechanical properties of concrete. This paper concentrated on performance parameters such as compressive strength, splitting tensile strength of the light weight concrete using LECA. The Lightweight concrete density varies from 40 % - 100 % replacement of LECA such as 1996kg/m3-1597kg/m3. It reduces the weight of concrete and cost of concrete by reducing the aggregate cost and produces economical system. In strength performance of 15 % replacement of fly ash content with 40 % replacement of coarse aggregates concrete for better results to ensure its optimal proportions.
