Sulphate-resistant Portland cement is manufactured through the precise grinding and thorough mixing of calcareous, argillaceous, and other materials rich in silica, alumina, and iron oxide. These components are subjected to clinkering temperatures, followed by grinding to achieve the desired cement quality outlined in this specification. Post-burning, only gypsum, water, or a maximum of one percent of air-entraining agents may be incorporated.

Sulphate Resisting Portland Cement (SRPC) is a specialized variant of Portland cement characterized by its low Tricalcium Aluminate (C3A) content, less than 5%, and a combined C3A and calcium aluminoferrite (C4AF) content of less than 25%. This composition minimizes the formation of sulphate salts, thereby lowering the risk of sulphate attack on concrete.

When subjected to designated testing methodologies, Sulphate Resistant Portland Cement must conform to the chemical and physical criteria outlined in the standard.

TESTS

Below are the primary tests for Sulphate Resistant Portland Cement are:

• Insoluble Residue

• Loss of ignition

• Fineness

• Setting time

• Soundness

• Compressive Strength

• Transverse Strength Test

An appropriately maintained laboratory is necessary for conducting various tests as per the methods outlined in the standard.

Packing and labeling must adhere to the specifications outlined in IS 12330. Each bag or drum of Sulphate Resisting Portland cement should bear the BIS Standard Mark (ISI Mark) on its label, ensuring compliance with the specifications. Manufacturers are required to obtain a BIS license from the Bureau of Indian Standards to use the standard mark (ISI Mark). This license is granted following a thorough assessment of manufacturing infrastructure, quality control measures, testing capabilities, and production processes.
