Fresh water savings through the use of municipal effluents in concrete pavement

Abstract

Wastewater reuse presents a promising solution to the growing pressure on the world’s water resources. The use of municipal wastewater effluents for concrete production in the construction industry would result in energy and water savings leading to conservation and sustainability of our water resources. In this research, to promote and increase the reuse of wastewater in construction industry, both chemical and bacteria analyses were performed to ensure the recommended quality for concrete mixing water and the compressive strength of concrete specimens made with wastewater effluents was investigated and compared to specimens made with fresh water. Statistical analysis of the strength results showed that at 95% confidence interval, the compressive strengths of the control specimens and those of test specimens are not statistically different.
