Strength and durability performance of Light Weight Self-Compacting Concrete (LWSCC) with Light Expanded Clay Aggregate (LECA)

Lightweight concrete(LWC) have been successfully implemented in the construction of structures for decades mainly due to its favourable material properties, especially their low specific weight in connection with a high capacity of thermal insulation, strength and durability. Development of Light Weight Self-Compacting Concrete (LWSCC) is an innovative step in the recent years in the construction sectors. LWSCC provides the combined favourable benefits of LWC with those of a Self-Compacting Concrete (SCC). Research work is aimed on development of (LWSCC) with the use of light aggregates namely "Light expand clay aggregate (LECA)". In this present investigation, five different mixes of (LWSCC) were casted and tested to find the workability and to calculate the mechanical properties at the age of 28 days. Water penetration test was conducted to examine the durability of LWSCC. Based on the results obtained, the best mix design was identified and selected for further investigation.
