Portland cement clinker is manufactured by defined raw materials containing CaO, SiO 2, Al 2 O 3, Fe 2 O 3, MgO, K 2 O, Na 2 O, etc. Homogenous mixtures of raw materials are developed for firing in the kiln. The clinker thus produced should contain at least two-thirds by mass of C 3 S, other phases of C 3 A, C 4 AF, and liquid.
