First, since the saturated state to the kettle state, that the moisture content of 60% to 35% range. With the reduction of moisture content, drying shrinkage increases. Drying shrinkage values ??have increased faster, since this part of the shrinkage value accounting to a pot full of water, state water content range of total shrinkage value of about 40%. Second, the autoclave to equilibrium state, i.e., moisture content of 35% to 4% range. With declining moisture content, drying shrinkage values ??rise above the range similar, but sometimes decline. However, when more than a state of equilibrium, with the further reduction in moisture content, drying shrinkage abruptly rise until a maximum value. Third, the moisture content of 5% to a range of absolute dry state. This is a range of products, most of aerated concrete equipment drying shrinkage phenomenon. In theory, this interval shrinkage value is too large, accounting for about 70% of the total shrinkage values, the structure is also great harm, which affects the quality of the brick body.
