The experimental work carried out aims to study on the strength properties of structural light weight concrete produced replacing coarse aggregate by blending light weight aggregates such as Cinder and Leca for M30 grade of concrete. The light weight aggregates such as Cinder and Leca were blended in various percentage proportions 0:100, 10:90, 20:80; 30:70; 40:60, 50:50 and vice-versa by volume of concrete to prepare light weight concrete. The properties such as compressive strength, split tensile strength and density are studied by casting 33 no. of plain cube specimens of size 150 x150 x150mm and cylindrical moulds of 150x300mm. M30 grade light weight concrete with 60% Cinder and Leca 40% had an average compressive strength of 36.52N/mm2 and split tensile strength of 2.5N/mm2. Addition of Ground Granulated Blast Furnace Slag (GGBFS) is used by replacing 20% of cement which enhanced the compressive strength to 39.20N/mm2.
