Mix Ratio Test and Basic Property Analysis for Autoclaved Aerated Concrete (AAC) Block
Through the mix ratio optimization test, the appropriate autoclaved aerated concrete block may be prepared for the production demand, whose technical indexes could satisfy the requirement of national specification. Furthermore, in the light of the research on the property of autoclaved aerated concrete block for this mix ratio, the strength of concrete block would decrease with the increase of total porosity among the pore diameter from 0.5mm to 1.5mm. The autoclaved aerated concrete block possessed the strong capability of absorbing water, so the volume water absorption rate increased quickly at first and then went down furiously, which could make the shrinkage of autoclaved aerated concrete block augment because of the decrease of its water absorption rate.
