摘要
KGF粉是以矿渣、硅灰和钛矿渣等多种材料按一定比例混磨而成的一种复合矿物超细粉．在混凝土外加剂的共同作用下，KGF粉可以很好地发挥火山灰效应、微集料填充效应和耐久性效应．由于减少水泥质量用量40％～60％，并大大提高了混凝土的抗硫酸盐侵蚀和抗酸雨能力，因此，KGF粉的应用是减少环境污染，提高混凝土在恶劣环境下耐久性的有效措施．
KGF powder is a complex mineral superfine powder made by grinding the mixs of slag, silica fume and titanium slag in certain proportion. The test results show that by the joint action with the concrete admixture, the pozzolanic, micro-aggregate filling and durable effects of KGF powder can be realized properly. The cement content is reduced by 40%～60%, and the resistance to sulfate attack and acid rain is enhanced greatly. Therefore, application of complex mineral superfine powder is an effective way to reduce environment pollution and improve durability of concrete under severe conditions.
