Abstract

This project investigates light weight concrete by replacing coarse aggregate with Light weight Aggregate (LWA). The methodology involves meticulous data collection, analysis, material selection, and the design of M30 grade concrete. It aims to evaluate how different proportions of LWA replacement affect concrete properties. Beginning with data gathering on conventional concrete mixes and LWA properties, material selection balances structural integrity with light weight characteristics. Varying percentages of LWA replacement (0%, 20%, 40%, and 50%) are then incorporated into the design phase, followed by precise mixing to maintain consistency. Concrete specimens undergo tests including slump, compaction factor, cube casting, and rebound hammer testing to evaluate workability, compact ability, and compressive strength. The project highlights the importance of the compressive test in determining concrete strength. Through meticulous analysis, it discusses LWA's effects on properties like workability, density, and durability, contributing insights into sustainable construction practices and emphasizing empirical analysis for engineering material selection.
