Investigation the mechanical properties of recycled expanded polystyrene (EPS) concrete is aim of this study. Seven recycled EPS concrete percentages are manufactured experimentally by replacing 0%, 15%, 20%, 25%, 35%, 45% and 60% of the coarse aggregate volume with recycled EPS, whereas the cement is replaced with 10% silica fume (SF). The mechanical tests conducted such as compressive strength, tensile strength, density and modulus of rupture. The results show that the decrease values of the compressive strength, splitting tensile strength and modulus of rupture of recycled EPS concretes with increase recycled EPS ratio about 50%, 41% and 60%, respectively (60% substituting of recycled EPS) compared to normal concrete. They also reveal that recycled EPS concrete density decrease about 30 % of normal concrete. The recycled EPS is useful in concrete and meets requirements.
