Study on the Formation of C₃S Doped with SO₃, BaO and MgO

Abstract:

Specimens were prepared by burning mixtures containing CaCO₃ and SiO₂ in 3:1 stoichiometric ratio along with dopants at different temperatures. Formation of C₃S doped with SO₃, BaO and MgO was studied. The results show that the temperature of beginning formation for C₃S is 1380°C in the system, and there exist both C₃S and C₂S. SO₃, BaO and MgO can effectively stabilize the M₁ and M₃type alites through substitution and interstitial imperfection, and make f-CaO content 8.68 wt% at 1450°C. C₃S doped with minor elements appears in the shape of six-party plate with the mean size of 17~30μm.
