Abstract – Structural lightweight aggregate concrete is an important and versatile material, which offers a range of technical, economic and environmental enhancing aspects. A decreased density for the same strength level reduces the self-weight, foundation size and construction costs. Structural lightweight aggregate concrete is generally used to reduce dead weight of structure as well as to reduce the risk of earthquake damages to a structure because the earthquake forces that will influence the civil engineering structures are proportional to the mass of those structures . The focus of present study explores the strength and durability properties of light weight aggregate concrete. Two varied types of light weight aggregates namely vermiculite and perlite is been partially replaced with coarse aggregate. Three different multistage mixing approaches were adopted with these two Light Weight Aggregates by various percentages (of weight), 15%, 20% & 25%, to replace coarse aggregates. The effects on using light weight concrete is studied by workability, compressive strength & split tensile strength.
