description The development of lightweight building materials has contributed to the construction industry, probably because of its advantages in terms of lower weight and low construction cost. One of the most demanded lightweight building material is lightweight concrete brick. Owing to rapid population growth, the Malaysian government is paying close attention to housing development, particularly in urban areas which consequently increase the bricks demand. Apart from the strong demand for bricks, the government is also concerned about the development of sustainable building materials. One of the most preferable lightweight material used in the production of lightweight concrete brick is Expanded Polystyrene (EPS). However concrete materials containing EPS were observed to be low in strength and fire resistance performance. On the other hand, Palm Oil Fuel Ash (POFA) which is unprofitable agricultural waste that is extensively generated by the palm oil mill has been categorised as one of the pozzolanic materials that could be used as a cement replacement. Additionally, it is found that the optimum amount of POFA replacement could enhance the strength and also fire resistance performance of a concrete materials. Therefore, in the present study a new combination of replacement materials which is EPS and POFA as sand and cement replacement in the production of lightweight concrete brick is proposed.
