An Experimental Study on Effective use of Effluent Wastewater in Concrete Preparation

Al Ajmi, Bothainah.

Nowadays fresh water is very limited in Oman and has lack of rain every year. But, concrete industry is still using fresh water to produce their product. This project is to investigate using treated effluent wastewater in concrete preparation as an alternative for using fresh water. The effluent discharge collected from Haya wastewater treatment plant, where the discharged effluent is collected in sewerage pipelines without affecting human and environment. According to this study, to make a value of treated effluent wastewater to be used in the construction industry in concrete casting and curing process. Chemical, physical and biological parameters in wastewater were collected directly from the treatment plant by using LIMS system. The produced concrete has a grade of C30 and the mixture consist of ordinary Portland cement, fine aggregate and coarse aggregate, and prepared by mixing with different water percentages of normal water and treated effluent wastewater. Based on American Concrete Institute requirement, the concrete mix proportions determined. Concrete quality checked with regarding to various tests and performing in the project study which are, slump test, compressive strength test, and split tensile strength test by using UTM. The purpose of these tests is to investigate the hardness and strength of the prepared concrete. The results conform using treated effluent wastewater with 100 % gives higher values in compressive strength and spilt tensile strength than use normal water. Also, heavy metals concentration results are within the limit of other standard effluent discharge standard, hence this test is important for checking the durability of concrete. Based on journals, the results of using treated effluent wastewater in concrete were investigated. The compressive strength and split tensile strength of the concrete is high and achieved the standard requirement. Also, was finding that the usage of acid solution is as removal for the toxic matter in concrete prepared with wastewater. So, usage of treated wastewater gives same normal water performance when added in concrete. However, all output from the literature review would be but into consideration in the project study.
