Abstract - To build environmentally sustainable structures, especially in developing countries, the possibility of using some agricultural wastes and industrial by-products from different industries as construction materials will be highly desirable and has several practical and economic advantages. Polystyrene (EPS) are widely using for many purpose including in construction industries. One of the major wastes in construction site is the polystyrene. Polystyrene are using as temporary block out of unfinished structure and architecture work such opening for slab, beam, wall and column. This phenomenon might lead to generate a lot of waste that can conclude as a material that not renewable. Malaysia also known as a country that produces palm oil, and this situation leads to generate a lot of agro-waste. Palm oil fuel ash (POFA) is an agro-waste resulting from the combustion of oil palm plant residue in palm oil industry. After the extraction of oil from oil palm fruit, both husks and shells are burnt resulting ash, known as POFA, is generally disposed of in open fields, thus creating environmental and health problems. Many researchers reported that properly processed POFA is adequately reactive and possesses good pozzolanic activity, and therefore can be used successfully as a supplementary cementing material for the production of concrete for building materials. Instead of just throw both of this wastes, it is better to study the potential of using both POFA and EPS to create a new sustainable, green material that will save our environment and also may lead to cost effective, time effective and energy saving in line with government target in eleventh plan. This paper provides a review of research on the capabilities of two materials namely EPS and POFA are used separately as substitutes in concrete and lightweight concrete bricks production. While in my study, this two materials were used according to the percentage to assess the effectiveness of POFA and EPS to be used in production of lightweight concrete brick converging on its mechanical properties and its workability as fire resistance.
