【摘要】 采用DSC、XRD、SEM等微观分析方法研究了S -激发剂对高钙粉煤灰膨胀水泥的增强机理。结果表明 :S -激发剂不仅能显著激发高钙粉煤灰的潜在水硬活性 ,而且能明显加快水泥矿物的水化 ,从而提高高钙粉煤灰膨胀水泥的强度。更多还原

【Abstract】 Enhancement mechanism of S-activator on high calcium PFA expansive cement was studied by means of DSC, XRD, SEM, etc. The research results indicate that S-activator can not only remarkably activate the latent hydraulic reactivity of the high calcium PFA, but also can promote the hydration rate of clinker minerals. The strength of the resultant cement is therefore improved.更多还原
