(一)引言波特兰水泥和净浆中的C_3S或β-C_2S在100℃或略高于100℃的水化产物,与常温形成的相比,虽然形态和显微结构有差异,但基本上没有区别。Odler和Skalny研究C_3S在25～100℃的水化,对于D—干燥材料来说,当H/S比从1.52减至0.98时,C—S—H中C/S比从1.88增至2.04。Bentur等发现,在65℃形成的C—S—H中,多硅酸盐多于在25℃形成 (a) Introduction The hydration products of C_3S or β-C_2S in Portland cement and pastes at 100°C or slightly higher than 100°C, compared with the formation at room temperature, although the morphology and microstructure are different, but basically There is no difference. Odler and Skalny studied the hydration of C_3S at 25 to 100°C. For D-dried materials, when the H/S ratio decreased from 1.52 to 0.98, the C/S ratio in CS increased from 1.88 to 2.04. Bentur et al. found that in the C-S-H formed at 65 °C, the polysilicate was formed at more than 25 °C
