ABSTRACT
In this research work, the effect of salt water on the compressive strength of concrete was investigated. This paper therefore present the result of findings of an experimental research on the effect of salt water on compressive strength of concrete for this concrete cubes were cast using fresh water and salt water for the design mix ratio of 1:2:4 from the concrete made from fresh water was 54mm while a value of 86mm was recorded from concrete made from salt water, concrete cubes were cast and cured with fresh water and the remaining cubes were cast and cured with salt water, the concrete cubes were cured for 7, 14, 21 and 28 days respectively. At 28 days, the rate of strength gain is still increasing in all the concrete cubes. The fresh water cubes also recorded its maximum strength at 28 days. Although the compressive strength of salt water concrete cubes was slightly of salt water concrete cubes was slightly higher than that of the fresh water concrete cubes. I therefore recommending that curing is very necessary in concrete in order to ensure the complex hydration of cement.
