以硅粉、粉煤灰和矿渣为矿物掺和料,采用XRD和SEM研究了矿物掺和料对水泥水化产物、水泥石结构和形貌的影响,探讨了酸溶液对水泥的腐蚀机理,并对矿物掺和料配比进行优化设计,以提高水泥的耐酸性.研究结果表明:掺加矿物掺和料有利于改善水泥石孔结构,降低水泥碱度,当硅粉、粉煤灰和矿渣以占水泥质量5%,10%和15%的配比掺入时,水泥的耐酸性最好.

Silica fume, fly ash and slag were chosen as mineral admixture, the influence of mineral admixture on cement hydration products, structure and morphology of hardened cement paste were analyzed by means of SEM and XRD. The mechanism of acid corrosion to cement was discussed and proportion optimization of mineral admixture was carried on to improve the acid resistance of portland cement. The results show that mineral admixture is beneficial to reduce alkalinity and improve the pore structure of hardened cement paste. When silica fume, fly ash and slag accounted for 5%, 10% and 15% of cement separately are introduced together, the acid resistance of portland cement is the best.
