Effect of Domestic Waste Water on the Strength of Concrete

Efficient water use is one of the most important requirements of cleaner production and the use of wastewater in concrete production important means to this end. However, there are no studies on the quality of concrete using wastewater and the activities in which wastewater can be used. The quality of concrete using wastewater and to propose guidelines for its treatment for non- potable applications. The type of water used for the mixing did not affect the concrete slump and density. Tests were conducted by 100% replacing the tap water with domestic wastewater in the concrete mixture. Domestic wastewater sample were collected from nalha near Sonegaon lake. The collected domestic wastewater and tap water were tastes and chemical analysis was carried out. The water samples, including a controlled portable (tap) water were analyzed for pH, total dissolve solids (TDS), chloride, hardness, alkalinity, and sulfates. Chemical analysis results showed that although the chemical compositions of wastewater were much higher than those parameters found in tap water, the water composition was within the ASTM standard limits for all substance indicating that the wastewater produced can be used satisfactorily in M25grade of concrete mixtures. For M25 grade concrete mix the total 18nos of 150mmx150mmx150mm cubes were cast. Cube compressive strength was also determined at 7 -days, 14 -days, and 28 -days of curing. Results indicated that the strength of concrete of the mixtures prepared using wastewater was comparable with the strength of the control mixture.
