随着我国经济发展以及房改、住房商品化的进展,人们对办公和居住条件要求越来越高,因此对建筑质量的要求也随之提高,这样对建筑墙体的裂缝控制要求显得更为严格。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。但是由于砌块强度等级低、吸水率高、收缩变形大,还是沿用传统的墙体砌筑与墙面抹灰工艺。经常出现墙体裂缝,由裂缝引起渗漏,墙面抹灰空股、开裂等质量问题。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。
With the economic development in our country and the progress of housing reform and housing commercialization, people are demanding more and more office and living conditions, so the requirements on the construction quality will also increase, which will make the crack control requirements on the building wall more strict . Fly ash aerated concrete block is a lightweight wall material, has good thermal insulation properties, construction is relatively simple, low prices. However, due to the low level of block strength, high water absorption, shrinkage and deformation, or follow the traditional wall masonry and wall plastering process. Frequent cracks in the wall cracks caused by leakage, wall plaster empty, cracking and other quality problems. 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.
