Quartz sand is generally used as a siliceous raw material for AAC production. The growth rate of tobermorite during autoclaving is controlled by dissolution of silica from quartz sand. And also, the theoretical proportion of dissolution of silica from quartz sand depends on Ca/Si ratio of raw materials. Therefore particle size distribution of quartz sand is very important for the production efficiency as well as the mechanical properties of AAC. In this paper, the optimal particle size distribution of quartz sand will be proposed.
