Performance Evaluation of Concrete with Replacement of Pumice and M-Sand: A Comprehensive Analysis

Abstract

Abstract Since there is a deficit of raw materials available for construction, concrete is essential in designing concrete structures in the modern world. As a result, the construction sector is now familiar with cutting-edge techniques that utilize waste material that is readily available for partial replacement by substituting alternative aggregates for regular aggregates. In this study, pumice stone located in the lowest section of the ocean or the abyss of red clay is utilized in place of concrete, with a replacement in a portion made of pumice mixed with cement. Concrete’s mechanical and physical durability was examined by measuring its Split and compressive strengths of ordinary concrete and substituting it with varying quantities of pumice (10% to 30%). M sand is entirely replaced in fine aggregate. From the previous studies, it shows the 50% of Coarse aggregate replacement and here we investigate how well partial pumice substitutions for coarse aggregate and M sand substitutions of fine aggregate can gain sufficient strength. Based on the experimental results, the current thesis compares the properties of conventional and replaced concrete for the various percentages of pumice stone replacement to coarse aggregate. It concludes that a 25% partial replacement by pumice yields the maximum compressive strength. We also studied the durability parameters in the present paper.
