White Cement and Concrete Compressive Strength in Sea Water Curing

Concrete is the most widely used construction material in the world, including in areas around the sea. Several previous studies have shown that sea water can reduce the strength of concrete. Therefore, research is needed to overcome this. This study aims to obtain the compressive strength of concrete treated in seawater by substituting portland cement with white cement, which is 10%, 20% and 30%. The results showed that the substitution of White Cement could increase the compressive strength of the concrete, both cured with fresh water and cured with seawater. The decrease in compressive strength of concrete that does not contain white cement is 11.28% greater than that of concrete containing white cement which is only around 4% on average.
