Mechanical properties of concrete containing expanded polystyrene (EPS) and palm oil fuel ash (POFA)

This study focuses on the application of expanded polystyrene (EPS) and palm oil fuel ash (POFA) as replacement materials in concrete. In this study, EPS was utilized to replace fine aggregate up to 20% in the concrete mixture. One the other hand, POFA replaced cement up to 30% in the concrete mixture. The chemical properties of POFA were determined using XRD analysis and compared with cement. The mechanical properties of concrete cubes containing EPS and POFA were determined based on workability, density, water absorption and compressive strength. The performance of the concrete containing EPS and POFA was then compared with the normal concrete. As a result, the performance of the concrete containing EPS and POFA was determined.
