Aerated concrete block equipment performance to explain the block. Henan hung skill in the use of a full set of aerated concrete equipment high quality production of aerated concrete blocks, high density, permeability, good sound insulation effect, the aerated concrete blocks (more than 100 labels brick) can replace with label use of ordinary clay. Hung skill in aerated concrete blocks mainly physical performance test, durability are as follows: dry heat temperature should not exceed 65 ℃, in order to avoid excessive dehydration aerated concrete blocks. Appropriately adjust the time according to the temperature conditions. According to technical requirements carbide, carbide strength loss after no more than 40% (ie carbonation coefficient of not less than 0.6 in order to observe aerated concrete blocks of acid and alkali resistance, we consciously select a good quality clay brick (852 brick) and cinderblock specimen placed in a 30% sodium hydroxide (caustic soda) solution and 30% sulfuric acid solution soak for 20 days, compressive strength determination. discovered aerated concrete blocks acid and alkali resistance better than clay, In particular, alkali resistance better than clay because aerated concrete blocks containing alkaline body, while in alkaline solution not only looks good, but the intensity has increased.
