Abstract

The water consumption keeps on increasing due to the huge increase in the overall human population. This increasing consumption presents the vital need for providing alternative solutions at which can preserve the increase in water use. Therefore, the reuse of wastewater is considered the best option in order to reduce or provide alternative use of water in multiple applications. One of the common ideas that were developed during the past few years is the use of treated water in concrete mixing and curing instead of using potable water. However, the major concern that was related to this aspect is the possibility of influencing the properties of concrete while using treated wastewater. The aim of this research is to examine the influence of using treated wastewater in the procedure of mixing and curing concrete cubes. Some of the concrete cubes will be mixed using potable water, while others will be mixed using secondary treated wastewater. The reached results in this research demonstrated that the use of treated and mixed wastewater accomplished higher compressive strength than the use of water. The highest compressive strength recorded was 41.63 MPa with anaverage value of 38.4 Mpa, which was designed through the use of treated water in the mixing and curing of concrete cubes. The consistency of concrete has a minimal effect when using the treated wastwater in the concrete mixture.This indicated that treated wastewater could be quite useful in terms of accomplishing required properties and results of compressive strength in the design of concrete mixtures
