| 摘 要： | 通过水化微量热、化学结合水测定和X射线衍射、热重-差热分析、扫描电镜等测试方法研究了3种高掺量矿渣、粉煤灰、石灰石复合水泥的水化性能，并与硅酸盐水泥的水化进行了对比。结果表明：高掺混合材复合水泥的水化放热特征与硅酸盐水泥有明显不同，早期水化反应速度低于硅酸盐水泥，但后期由于矿渣、粉煤灰的二次水化反应使其水化速度增长较快。主要的水化产物亦为水化硅酸钙凝胶、钙钒石和Ca(OH)2晶体，但Ca(OH)2含量明显低于硅酸盐水泥浆体中的Ca(OH)2含量。

| Abstract: | Hydration properties for the three kinds of composite portland cement made of a large amount of slag, fly ash and limestone were studied by micro-calorimeter, chemically combined water, X-ray diffration, thermogravimetric analysis, scanning electron microscope, etc. Results show that the characteristics of hydration heat of the composite portland cements are distinctively different from those of the portland cement. For the blended composite portland cement, the early hydration rate is lower than that of portland cement, but the late hydration rate is increased quickly due to the secondary hydration of slag and fly ash. Hydration products of the blended composite portland cements are mainly CHS gel, ettringite and calcium hydroxide crystals, but the content of calcium hydroxide is apparently lower than that of normal portland cement. |
