摘要
研究了中性钠盐碱矿渣水泥在酸性溶液、硫酸盐溶液和海水中的抗化学侵蚀性能。借助X-射线衍射和压汞测孔法考察了中性钠盐碱矿渣水泥的水化产物及水泥石孔结构特征, 并指出高稳定性的水化产物和优良的孔结构是其具有优异抗化学侵蚀性能的主要原因。
The resistance to chemical attack of NSAAS cement in acid solution, sulfate solution, sea water was studied. By means of XRD and mercury intrusion porosimetry, the hydration products of NSAAS cement and the characteristics of pore structure of hardened cement paste were inspected. It was pointed out that high stability of hydration products and excellent pore structure were main reasons why NSAAS cement possessed excellent resistance to chemical attack.
