The phase composition of a cement clinker can be calculated from the values of the chemical analyses according to R.H. Bogue. For a cement clinker of usual composition, which contains C3S, C2S, C3A and C4AF and has the AR >0.638, the following formulae can be used: C3S = 4.071*CaO – 7.600*SiO2 – 6.718*Al2O3 – 1.430*Fe2O3
