粉煤灰加气混凝土砌块是一种轻质墙体材料,具有良好的隔热性能,施工较为简便,价格低廉,是满足建筑节能要求的一种墙体材料。加气混凝土砌块墙体施工中,由于砌块强度等级低、吸水率高、收缩变形大,经常出现墙体裂缝,由裂缝引起渗漏,墙面抹灰空鼓、开裂等质量问题。
Fly ash aerated concrete block is a lightweight wall material, has good thermal insulation properties, the construction is relatively simple, low price, is to meet the requirements of a building energy-saving wall materials. Aerated concrete block wall construction, due to the low level of block strength, high water absorption, shrinkage deformation, often appear cracks in the wall, cracks caused by leakage, wall plastering hollowing, cracking and other quality problems.
