Abstract
Abstract: This study examined the structural behavior 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%. Analysis of this concrete was done in fresh state as well in hardened state to evaluate 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.
