高岭土尾砂在高强混凝土中应用的试验研究

Experimental Research on High Strength Concrete with Kaolin Tailings

利用机械力活化方法,对高岭土尾砂进行了活化研究,采用对比试验,对活化后的高岭土作混凝土掺合料配制C70高强混凝土的力学性能和耐久性进行了研究.结果表明,经过机械力火化后的高岭土的活性与偏高领土相近.高强混凝土中掺入高岭土不仅能满足强度等级要求,而且能提高混凝土的渗透性,具有显著的经济效益与社会效益.

Kaolin active was focused on with mechanical activation to produce C70 by researching on mechanical and durability properties. The results show that the active of kaolin tailings is nearly to metakaolin, and kaolin tailings added in concrete not only increase the concrete strength, but also improve the impermeability, which has a significant economic and social effect.
