About 9095% of a Portland cement is comprised of the four main cement minerals, which are C 3 S, C 2 S, C 3 A, and C 4 AF, with the remainder consisting of calcium sulfate, alkali sulfates, unreacted (free) CaO, MgO, and other minor constituents left over from the clinkering and grinding steps. The four cement minerals play very different roles in the hydration process that converts the dry cement into .

Nov 19, 2012· Use as alternative raw material in cement production Clinker: Fly ash from coalfired power plants can be used effectively as a component of raw kiln feed for the manufacture of cement clinker. Fly ash contains significant amounts of Al 2 O 3 and SiO 2 and has thus been used as a partial replacement of natural raw materials like clay and/or shale in the raw kiln feed.
