Studies on Structural Light Weight Concrete by Blending Light Weight Aggregates

Mr. Anil Kumar R; Dr. P Prakash

Abstract

In this present experimental work, a attempt is made 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 M20 grade of concrete. The light weight concrete is prepared by using Cinder and Leca as light weight aggregates which were blended in various percentage proportions 0:100, 10:90, 20:80; 30:70; 40:60, 50:50 and viceversa by volume of concrete. By using this, 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. M20 grade light weight concrete with 60% Cinder and Leca 40% had an average compressive strength of 28.89N/mm2 and split tensile strength of 1.67N/mm2 . The Ground Granulated Blast Furnace Slag (GGBFS) is used by replacing 20% of cement which enhanced the compressive to 30.68N/mm2
