蒸压灰砂砖和蒸压加气混凝土砌块墙体开裂的机理分析和防裂漏措施.doc

通过比较蒸压灰砂砖和蒸压加气混凝土砌块与传统红砖的特性，分析新墙材开裂的机理，提出相应的防裂漏措施。 关键词：蒸压灰砂砖和蒸压加气混凝土砌块；开裂机理；防裂漏措施。 一.概述 蒸压灰砂砖和蒸压加气混凝土砌块是近年来我市使用较多的新型墙体材料，但使用后会遇到墙体开裂、渗水，抹灰脱落从而污染、损坏室内装修等问题。经过对我公司近年承建的工程进行调研，发现：并不是只有使用蒸压灰砂砖或蒸压加气混凝土砌块的框架或框剪结构的填充墙会出现开裂或渗漏现象，使用红砖的也会出现，只不过使用新墙材的比使用红砖的多一些；并不是每一堵使用新墙材的墙都会出现裂漏，而且出现的位置和方式各不相同，向西方向的By comparing the sand lime bricks and autoclaved aerated concrete block and brick traditional features of the new wall cracking, and proposes appropriate measures to crack leak. Keywords: sand lime bricks and autoclaved aerated concrete block; cracking mechanism; crack leakage measures. 1. Overview and autoclaved lime sand brick autoclaved aerated concrete block is used frequently in the city in recent years, new wall materials, but the use would face the wall cracking, water seepage, falling plaster to pollution, damage interior decoration and so on. Through our research projects constructed in recent years, found that: not only the use of autoclaved lime sand brick or autoclaved aerated concrete block of the frame or frame structure of the filler wall cracking or leakage occurs, use the red brick The will also appear, but the use of new wall materials more than the use of red brick; not every block walls with new wall will appear cracking and leakage, but there is also the location and different way, westward direction
