ABSTRACT - The increasing demand for freshwater resources and the growing concerns over water scarcity have created a need for sustainable alternatives in construction practices. Concrete production, which consumes a significant quantity of potable water, offers potential for conservation through the use of treated wastewater. This study presents an experimental investigation into the suitability of treated municipal wastewater as a replacement for potable water in M40 grade concrete.
Concrete specimens were prepared using identical mix proportions designed in accordance with IS 10262:2009 and IS 456:2000, with the only variable being the type of mixing water. The quality of treated wastewater was evaluated based on key physicochemical parameters to ensure compliance with standard requirements. The performance of concrete was assessed through compressive strength testing at curing ages of 7, 14, and 28 days.
The experimental results indicate that concrete produced with treated wastewater exhibits strength characteristics comparable to conventional concrete made with potable water. At 28 days, the treated wastewater concrete achieved approximately 97% of the compressive strength of the control mix, with only minor variations observed at earlier ages. These variations are attributed to the presence of dissolved constituents in treated wastewater, which may slightly influence hydration behavior without adversely affecting overall performance.
The findings demonstrate that treated wastewater can be effectively utilized in concrete production when it meets permissible quality standards. This approach contributes to the conservation of potable water resources and supports sustainable construction practices. The study highlights the practical feasibility of wastewater reuse in concrete and encourages its adoption in regions facing water scarcity.
