It is a sulfate resistant cement and is produced by grinding sulfate resistant clinker with a low percentage of gypsum. It is in conformity with GSO SASO GSO 1917/2009, and the sulfate resistant clinker is obtained by controlling the amount of the tri-calcium aluminite (C3A) in clinker which it is the main element that affects sulfur resistance. The sulfate resistance cement(SRC) is used in the presence of sulfates in soil and groundwater that may cause damage to ordinary Portland cement. Sulfates generate a series of chemical reactions with sulfur ions and thus produce a larger volume of auxiliary reactions, thus causing internal and damaging to the concrete elements.





It is used within the concrete structure described in a sulfate-rich environment, sewage installations, large concrete structures, pegs, foundations, underground concrete structures and prefabricated concrete.
