Abstract

The characteristics of cinker in the C₃S-C₂S-C₁₁A₇ ·CaF₂-C₄AF system vary depending on the cooling rate and change the early hydraulic properties of the cement. The size of alite becomes small with cooling rate and the fine crystals of alite which precipitated at cooling process coexist with the crystals of alite which precipitated at burning process in case of rapid cooling. The above changes in fine textures have a close relationship to the content of SiO₂ in the solid solution of C₁₁ A₇·CaF₂. The amount of SiO₂ and other impurities in C₁₁A₇·CaF₂ give a considerable influence on the early hydraulic activity of the phase; with the decrease in impurities, that is, with the decrease in cooling rate, the activity becomes high.
