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。是我国夏热冬冷地区唯一能以单一材料方式满足建筑节能要求的墙体材料。武汉地区普遍用于框架结构非承重墙体建筑。分析了粉煤灰加气混凝土砌块墙体裂缝形成原因,并提出了解决墙体裂缝的各种技术措施。 Fly ash aerated concrete block is a lightweight wall material, has good thermal insulation properties, construction is relatively simple, low prices. It is the only wall material that can meet the requirements of building energy conservation in a single material way in the hot summer and cold winter area in China. Wuhan is generally used for frame structure of non-load-bearing wall construction. The reason of crack formation in fly ash aerated concrete block wall was analyzed and various technical measures to solve the crack in wall were put forward.
