What is Sulphate Resisting Cements?
Sulphate can be found in natural and industrial wastes as well as in soils. Soluble sulphates can react with lime and aluminates present in the hardened Concrete and form respectively gypsum and ettringite. Both reaction involves expansion and consequent concrete deterioration. Sulphate Resisting Cement are characterised by a low C3A content to minimise the risk of ettringite formation.
