QUALITY MANAGEMENT
Sulphate resistant Cement’s best quality is to provide effective and long lasting strength against sulphate attacks and is very suitable for constructions near sea shores as well as for canals linings. It provides very effective protection against alkali attacks.

Sulphate Resistant Cement is a dark colored Portland Cement manufactured from clinker of low C3A content and undergoes grinding with a reduced proportion of Gypsum than Ordinary Portland Cement, Sulphate Resistant Cement Grade 42,5 R is available in the packaging of 50 Kg P.P Bags, 50 Kg 3 Ply Paper Bags, 1 Metric Ton Jumbo Bags, 2 Metric Ton Sling Bags.
