Cement
SRPC (Sulphate Resisting Portland cement)
Sulfate Resisting Portland Cement is a sort of Portland concrete in which the amount of Tricalcium aluminate (C3A) is confined to lower than 5 % and (2 C3A + C4AF) is lower than 25%. SRC can be utilized for basic cement wherever OPC or PPC or Slag Cement is usable under ordinary conditions. The utilization of SRC is especially helpful in such conditions where the solid is presented to the danger of disintegration because of sulfate attack. Sulfate Resisting Cement is produced from a union of various particular standard crude materials of high immaculateness under strict supervision of a specialist specialized group.
