calcium sulphate was added to a high silica ratio, low iron mix to stabilize C2S to an inter-mediate temperature of ca. 1480 C. Above this temperature, loss of stabilization coincident with desulphation resulted in the formation of C3S with a characteristic microstructure in which free lime occurred as inclusions within the alite.

The lime saturation factor controls the potential C3S Alite to C2S Belite ratio in the clinker. C3S controls the early age strength development while C2S controls the later age strength. The LSF is a ratio of CaO to SiO2, Al2O3 and Fe2O3 main oxides of clinker it is calculated as LSFCaO2.8 SiO2 1.2 Al2O3 0.65 Fe2O3.
The Effect Of Differences In The Composition Of
It was found that the composition of the cement did have an effect but not as great as did differences in the curing regime. The concretes made with the higher C3SC2S ratio cements had properties which were as good as, or in some respects superior to, those made with cements with a low C3SC2S ratio.

Oct 07, 2013 For SO3Alkali ratios between about 1 and 2, the excess SO3 reacts with K2SO4 and CaO to form calcium langbeinite 2CaSO4.K2SO4, preventing the equivalent amount of CaO from reacting to form C3S. For SO3Alkali ratios from about 2 to 4, it is likely that the excess SO3 is present in solid solution within the silicate minerals, particularly C2S.
