Abstract:-Â Concrete is made by combining cement, water, and aggregate (coarse and fine) materials such as gravel and sand. Water is required to react with the cement in order for the hydration process to commence. Water is thus one of the most significant ingredients in the manufacturing of concrete. The physicochemical properties of cassava effluent and water polluted with cassava effluent were taken to the KAPPA Biotechnology Laboratory in Ibadan, where various elements present in the samples such as cyanide, cadmium, magnesium, calcium, copper, iron, and lead, among others, were analysed and compared to WHO standards. Slump, compaction factor, compressive strength, and split tensile tests were performed on concrete mixed with potable water and cured in potable water (A); concrete mixed with potable and cured in cassava effluent (B); concrete mixed with cassava effluent and cured in cassava effluent (C); concrete mixed with cassava effluent and cured in potable water (D); concrete mixed with polluted water and The findings revealed that cassava effluent and water polluted with cassava effluent have no discernible effect on the workability of concrete made with them when compared to concrete made with potable water; however, concrete made/cured with cassava effluent and water polluted with cassava effluent had lower strength in mixing and curing when compared to those made with potable water. Based on the decrease in the values of the Slump, Compacting factor, Compressive strength, and Split tensile strength of concrete made with either cassava effluent or water polluted with cassava effluent in mixing or curing, it can be concluded that cassava effluent or water polluted with cassava effluent should be discouraged for mixing or curing of concrete as these will have negative effects on such concrete.
