Abstract
Abstract
This study presents the effect of curing conditions towards properties of lightweight concrete brick made up of cement, sand and some replacement materials. The replacement materials used in this study is Expanded Polystyrene (EPS) as sand replacement and Palm Oil Fuel Ash (POFA) as cement replacement. The percentage of replacement for POFA is 0%, 10% and 20% whilst 0%, 30% and 50% for EPS. The brick samples have been exposed to different types of curing conditions that is air curing and water curing until the day of test. Among the tests that have been conducted are hardened brick density, compressive strength and water absorption. Based on the findings, it has been proved that the replacement percentage of EPS and POFA has significant impacts towards the brick properties. In addition, it is found that hardened brick density and compressive strength of air curing samples are lower as compared to water curing samples meanwhile the water absorption for air curing samples are higher that water curing samples.
