The high demand for concrete production generates wastewater which causes environmental problems. However, if wastewater is able to be recycled as part of engineering construction materials, many benefits can be reaped. Unfortunately, the use of wastewater in manufacturing concrete is not common. Therefore, this research aims to identify the influence of using slurry water and car wash wastewater on concrete properties, focusing particularly on its mechanical properties. The basic characteristics of wastewater were studied according to USEPA method while the properties of concrete with wastewater were compared according to ASTM C1602 and BS EN 1008 standards. In this paper, the compressive strength, modulus of elasticity and tensile strength were examined in order to determine the mechanical properties of concrete. The wastewater was replaced in the concrete mix from 0% up to 40%. The results indicated that the characteristics of wastewater complied with the BS and ASTM standards. In addition, the results also recommended that the concrete mixture with 20% of wastewater has given the highest compressive strength and modulus of elasticity.
