| 摘 要： | 为了有效利用湿排粉煤灰及电石渣等资源,用其二者制备高活性矿物掺合料浆.研究了湿排粉煤灰复合电石渣矿物掺合料浆的制备工艺及其所配制净浆试件各龄期强度与水化产物(XRD、SEM)的变化.结果表明:湿磨配浆过程中,湿排粉煤灰与电石渣(固含量)存在最佳质量比75:25.高Ca(OH)2含量的电石渣及改性剂促进水泥水化所提供的碱性环境有利于激发粉煤灰颗粒的早期活性,促进了其二次水化反应的进行.

| Abstract: | To recycle wet-discharged fly-ash and carbide lime effectively,a highly-activated mineral admixture slurry consisting of both these components was investigated.The preparation technology of mineral admixture slurry made from a composite of wet-discharged fly-ash and carbide lime and the strengths,hydration products change(XRD,SEM) of cement paste made by the slurry were studied.The results indicate that the optimal proportion between wet-discharged fly-ash and carbide lime(solid content) is 75:25 in the pro... |
