浅谈混凝土空心砌块墙体开裂原因及防治

近年来，为了节约土地资源，保护环境，节约能源，我国政府正在大力推行取代传统粘土砖的新型墙体材料。新型墙体材料主 要有烧结多孔砖、空心砖、多孔砖、煤矸石普通砖、粉煤灰烧结砖、蒸压灰砂砖、混凝土小型空心砌块、轻集料砌块、陶粒砌块、 加气混凝土砌块、石膏砌块、轻质墙板、复合墙板等，目前，多采用砌块墙体。但随着混凝土砌块大量用于房屋建筑，墙体普遍出 现了较严重的开裂，墙体开裂问题日益突显。墙体的开裂，给人们造成了一种不安全感，因此也成为老百姓投诉的新热点。混凝土 砌块墙体开裂的原因是多方面的，也是很复杂的。

一、砌块材料自身的原
Cracking of concrete hollow block wall causes and prevention

In recent years, in order to save land resources, environmental protection, energy conservation, our government is promoting the new wall to replace the traditional clay brick materials. There are new wall materials sintered porous brick, hollow brick, brick, brick by coal gangue, fly ash brick, sand lime bricks, concrete hollow block, lightweight aggregate block, ceramic blocks, plus aerated concrete block, gypsum block, light weight wall panels, composite wall panels, at present, more use of block wall. But with the large concrete blocks used in building construction, walls generally appeared more serious cracking, wall cracking is increasingly highlighted. Wall cracks, to the people created a sense of insecurity, it has become a new hot spot for people complaints. Cracking of concrete block walls are many reasons, but also very complicated.
