SRPC is
a type of Portland cement in which Tricalcium Aluminate (C3A) amount is less
than 5% and the amount of C3A and calcium aluminoferrite (C4AF) together is
less than 25%. Use it where there the concrete structure faces the risk of
being damaged by high amount of sulphates found in its immediate environment.
The use
of SRPC is recommended in places where the concrete is in contact with the
soil, groundwater and seawater, and/or exposed to seacoast. In all these
conditions, the concrete is exposed to attack from sulphates that are present
in excessive amounts, which damage the structure.
Characteristics
Provides
maximum resistant to chloride ions, minimising the risk of corrosion of
reinforced steel
High
level of concrete performance and structural integrity in highly aggressive
sulphate and acidic environments
Can
significantly improve later-age concrete strength
