Lightweight cement hybrid materials based on expanded polystyrene (EPS) foam waste and coconut coir fiber (CF) have been developed as an effective method for industrial and agricultural wastes management. The purpose of this study is to investigate the effects of CF and EPS foam as cement replacements at various proportions of EPS foam and CF at various lengths of CF on the properties of cement composites. The mixtures containing partial replacement of cement by 1, 2 and 3% CF with three different CF lengths (1, 2 and 3 cm) and 1, 2 and 3% EPS foam were prepared. The physical and mechanical properties of the specimens were determined after 28 days of hydration. The flexural strength and impact strength of the composites increased with CF content. Meanwhile, the bulk density clearly decreased along with the addition of EPS foam. The cement composites containing 3% CF and 1% EPS as well as 2% CF and 2% EPS at 2 cm fiber length showed acceptable strengths and density for structural lightweight cement. The results indicated that EPS foam and CF can be used as replacements for cement and asbestos in the production of fiber board cement to obtain inexpensive, lightweight and strong product.
