Abstract:
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.
