Abstract

Lightweight concrete can be formed from the main element of concrete with some replacement material. The main problem on this study is the price of the raw material is getting expensive day by day such as coarse aggregate due to reduction of natural resources and high demand in construction industry. The objective of this research are to identify the suitable composition of polystyrene concrete mix, to identify the workability of polystyrene concrete and to compare the strength of the normal concrete mixture and polystyrene concrete mixture. A series of concrete cubes with proportion of 1.5%, 2.5% and 3.5% polystyrene beads are used in this study to assess the influence of different volume of polystyrene to the structural performance. To identify the workability of concrete mix, the slump test had been conducted during the mixing process. Meanwhile, the compressive strength was conducted to determine the strength performance of the concrete cubes. At the end of study the highest percentage compressive strength contributed by 1.5% of polystyrene compare to other proportion. Hence, all the proportion have a good workability thru the slump test. Even though, the strength of polystyrene concrete still does not meet the strength of ordinary concrete. Therefore, the optimum percentage polystyrene concrete is 1.5% with a good workability with 2.4 KN compressive strength. It suggested that to use superplasticizer to reduce the good bonding between polystyrene and concrete mixture.
