Abstract

Lightweight concrete (LWC) is a technology in the construction industry, and has become popular in the past fewdecades due to its benefits. There are a lot of construction wastes generated in Malaysia due to the rapiddevelopment in the construction industry. Brick is one of the construction wastes in Malaysia. Hence, this researchwas focused on 28-day compressive strength of lightweight concrete with crushed clay brick’s waste as areplacement to coarse aggregate. The density test, water absorption test, and slump test values were alsodetermined. The raw materials used in this research were Ordinary Portland Cement (OPC) as binder, sand as fineaggregates and crushed clay brick’s waste (CCBW) as coarse aggregate, and a total of 48 concrete cubes wereproduced with ratio of 0%, 10%, 20% 30% 40%, and 50% of CCBW. In this study, the CCBW had higher waterabsorption characteristic. Workability and compressive strength values increased when the percentage of CCBWwas applied in LWC mix. The slump value was above 200mm height of slump, and the compressive strength alsoachieved minimum requirement of 28-day compressive strength of 17MPa. The findings from this study willhopefully reduce construction wastes in Malaysia, and produce sustainable LWC
