SO3 (sulfur xide) is an indirect measure of the amount of gypsum or calcium sulfate (CaSO4) in the cement. As discussed above, SO3 helps control C3A reaction. The amount analyzed consists of both the sulfate (SO3) in the cement clinker and the amount added during grinding, typically in the form of the mineral gypsum.

Cement is typically made from limestone and clay or shale. These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. This blended raw material is called the 'raw feed' or 'kiln feed' and is heated in a rotary kiln where it reaches a temperature of about 1400 C to 1500 C.

1. Introduction. In civil engineering applications, cementbased materials (CBMs) are substantially used due to their low cost, simple production, and extensive sources [1,2,3,4,5,6,7,8].However, the factors limiting their further applications include their brittle nature, low tensile strength, weak resistance to cracks, low energy absorption, and small strain capacity [9,10,11,12].
