Sulphate Resistant Cement
CEM IV/A (P) 42.5 SR
Sulphate-resistant cement is recommended for use in concrete exposed to large sulphate levels. It is the result of crushing clinker and gypsum to fulfill the requirements of the standard specifications the ES 4756-1/2022 and EN 197-1/2011. The cement’s sulphate resistance is due to its low tri-calcium aluminate (C3A) content..
