Strength performance of concrete cured in oil spillage contaminated water source in Akwa Ibom State

Concrete interacts with substances within its environment. These interactions often have significant effects on the properties of concrete made from ordinary Portland cement. The study assesses the effects of oil spillage contaminated water curing on the performance of concrete. The parameters st...
