Grinding Aid Effect of Different Siliceous Material for Quick Lime

Abstract

Different siliceous materials were selected for grinding aid agent to studying the effect for specific surface areas of quick lime and autoclaved samples compressive strength. The results show, grinding aid effect of quartz sand, waste lime sand brick and fly ash are significant for block quick lime. The rational contents of grinding aid agent are about 10%. And grinding aid effect of quartz sand is best. The compressive strength of autoclaved samples improved obviously with lime mixed the grinding aid agent, and the compressive strength increased range of autoclaved sample is more than 50%. The effect of different grinding aid agent for improving compressive strength of autoclaved samples is obviously different, and the improving strength effect of fly ash is best for grinding aid agent.
