Study on Strength and Durability Characteristics of Light Weight Aggregate Concrete

Abstract

This study focuses on lightweight concrete (LWC), Although the majority of studies on LWC focus on "semi-lightweight" concrete, which is made with lightweight coarse aggregate and natural sand to create "totally lightweight" concrete, using waste materials in place of the fine light weight aggregate can have more positive environmental and financial effects. Synthetic lightweight aggregate made from environmental waste is a possible new supply of structural aggregate material as concerns about the overuse of natural aggregates grow. The self-load of a structure was significantly lowered when structural grade lightweight concrete was used . In this work, the mechanical and durability characteristics of a structural grade lightweight aggregate are investigated and reported. Test programme includes the test of conventional or normal weight concrete, light weight aggregate concrete for compressive strength , split tensile strength, Flexural strength and durability test after 28 and 90 days curing
