Experimental Study on Concrete with Pumice Stone and Leca Aggregate as a Partial Replacement of Coarse Aggregate

Structural light weight aggregate concrete is an important and versatile material in modern construction. The main objective of using LWAC is normally to reduce cost by reducing the dead load of structures. In this study an attempt has been made to study the mechanical properties of concrete M30 using the light weight aggregate pumice stone and leca aggregate as a partial replacement to coarse aggregate. For this purpose concrete is made by partial replacement of coarse aggregate with different ratio of pumice and leca aggregate with different percentage and thereby achieving the target strength with low density of concrete. The properties such as compressive strength, tensile strength and flexural strength and density are studied by casting cube specimens of size 150mmx150mmx150mm and beam 150mmx150mmx700mm.The results are compared with conventional M30 grade concrete.
