Abstract

The objective of the project was to investigate the potential of using car washing wastewater in cement mortars and concrete concrete. Wastewater samples were collected from five car washing stations in the Muscat Area. Chemical analysis was carried out on these samples to determine their chemical composition. To study the effect of wastewater on the mechanical properties of cement mortars, samples with 100% wastewater substitution for tap water were prepared and tested at 3, 7, 28, 56, 90, and 180 days of curing. Also, concrete mixtures with different proportions of wastewater (0, 25, 60, 75, and 100%) were prepared and tested at 7 and 28 days of curing. Compressive strength as well as flexural and tensile strengths were determined. In addition to strength-based tests, scanning electron microscopy was performed to determine the micro structure of the cement mortar samples prepared with 100% wastewater. Results indicated that there is some variability in the chemical composition of the wastewater samples, but the strengths are not significantly affected with this variation.
