Abstract

With the usage of lightweight concrete is growing in tandem with technological advancements, it is vital to study and investigate lightweight concrete using natural elements such as pumice. Pumice, a volcanic material, is utilized in the manufacturing of lightweight aggregate concrete (LWAC) as a partial replacement for natural aggregates. The mechanical and (LWAC) thermal properties were examined in this work using a locally accessible light-weight aggregate (LWA) named “Pumice Aggregate” (PA). This paper studied at partial replacement of coarse and fine aggregate with pumice 20 %, 40 %, 60 %, 80 %, and 100 % by volume for coarse aggregate and 50 percent and 100 percent for fine aggregate. This study is focused to determine the mechanisms of LWAC to discover the PA. optimal replacement. Compressive strength, density, and total water absorption have been tested on LWAC. The LWAC has appropriate strength and density, according to the findings. However, in comparison to standard concrete, LWAC incorporating PA has lesser workability and strength while still allowing for appropriate water absorption. LWAC is widely employed in a variety of civil engineering applications, including pumice block walls that insulate both sound and heat while lowering building's dead load.
