In this research, the strength and economic viability of 210 kg/cm² concrete were evaluated using treated wastewater from a Wastewater Treatment Plant (WWTP) in Lima and the addition of microsilica. After assessing the water quality, four concrete mixtures were designed: the control concrete (made with potable water), concrete with 50%, 75%, and 100% WWTP water, and each mixture was supplemented with 6% microsilica. Additionally, compressive, tensile, and flexural strength tests were conducted to evaluate the performance in columns and beams at the ages of 7, 14, and 28 days. The results indicated that the concrete made with 50% WWTP water achieved a maximum compressive strength of 294.5 kg/cm² compared to 277.1 kg/cm² of the control concrete; the concrete made with 50% WWTP water achieved a maximum tensile strength of 36.9 kg/cm² compared to 32 kg/cm² of the control concrete; and the concrete made with 50% WWTP water achieved a maximum flexural strength of 56.9 kg/cm² compared to 48.1 kg/cm² of the control concrete. Furthermore, the cost analysis indicates a cost saving of over 50%-98% when using treated WWTP water instead of potable water for concrete production. Finally, a potential positive impact is demonstrated by achieving similar performance and significant savings using concrete with treated wastewater.
