The study focuses on investigating the potential of using recycled wastewater from various sources in the mixing and curing processes of concrete, aiming to address the environmental issues related to clean water availability and wastewater disposal. The researchers collected wastewater from four different sources, namely the sewage treatment plant industry (food-based industry), acid-containing aluminium industry, acid-free aluminium industry, and sewage treatment plant. For comparison, normal tap water was used as a control sample. Concrete mixes were prepared using both wastewater and tap water, and the curing process was carried out using the same water source. The performance of the concrete mixes was assessed based on parameters such as compressive strength, split tensile strength, water absorption, and corrosion current density. The microstructure of the concrete mixes was examined using scanning electron microscopy (SEM) and X-ray diffraction (XRD). The properties of different water sources were also compared. The results indicated that concrete mixed and cured with wastewater exhibited lower compressive strength compared to the control mix prepared with tap water. Additionally, the water absorption of the wastewater mixes was higher than that of the control mixes. The study also explored the microstructure of the concrete mixes through SEM and XRD analyses. The keywords associated with this study include wastewater, concrete, compressive strength, and corrosion.
