In the system CaO-SiO2-Al₂O₃-Fe₂O₃-MgO-SO₃ it is possible to identity 6 different equilibrum phase associations relevant to the production of belive cement clinker. On the basis of the algorithm given in [1], the qualitative and quantitative phase composition of the equilibrium product is determined in terms of the composition of the raw material mix containing model limestone and clay. The sensitive dependence of the hydration properties of the product on the parameters of clinker preparation is given by the large number of various phase associations within the narrow range of raw material composition and by kinetic factors.
