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

AM signifies the temperature at which liquid formation starts, the nature of liquid formed and the color of clinker formed. The lowest temperature is obtained at AM equal to 1.6, which is the optimum for clinker formation and nodulization. Higher the AM, lighter the color of clinker (cement). Normal range of SM is 1-2.5.
