摘要
提出了一种矿渣硅酸盐水泥水化反应的理论模型,考虑了矿渣成分、熟料成分、矿渣掺量、矿渣水化程度对其水化产物成分和微观结构的影响,可以定量地预测C-S-H凝胶的成分和浆体不同组份的相对比例.与普通硅酸盐水泥浆体相比较,矿渣硅酸盐水泥浆体最主要的差别是Ca(OH)2含量显著降低、C-S-H的钙硅比明显降低,同时孔隙率也不断增加.
A theoretical model is proposed for the hydration of slag-blended cement. The model takes into account the effects of the composition of cement, that of slag, the proportion of slag, the hydration degrees on the composition and microstructure development of slag-blended cement paste. The composition of hydration products and their relative proportions can be quantified with this new model. The main differences between the Portland cement paste and slag-blended cement paste are that the contents of Ca（OH）2 are obviously lower in the latter, and the porosity is much higher.
