Sulphate Resisting Portland Cement (SRPC)

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
