Abstract

This paper explains the comparative studies on partial replacement of expanded perlite as coarse aggregate. Perlite is basically the mineral obsidian. It is naturally occurring siliceous volcanic rock. Utilization of natural resources of environment is essence of any development in concrete. Perlite gives excellent insulating properties at temperature varying from very low and very high. Using expanded perlite aggregate in concrete the total amount of cement content 70% and fly ash 30% replacement of cement. The combination reducing the effect of thermal conductivity in light weight concrete. In light weight concrete addition of perlite is reduced the density of concrete. The flexural and compressive response of concrete to be determined and 0% to 30% replacement of fine aggregate using expanded perlite. Optimum percentage of partial replacement of aggregates were obtained by conducting various strength tests such as compression and flexural strength on the casted specimens such as cubes, cylinders, prisms and beams.
