| 摘 要： | 小型混凝土空心砌块的湿胀干缩性能是引起砌块建筑易裂的主要因素之一，可通过采取有效措施控制二次干缩引起的变形进行防治。本文通过四片尺寸相同、构造措施不同墙体的试验，并借助有限元程序研究分析了环境相对湿度、时间、面层材料、含水率等对小型空心砌块墙体二次干缩的影响，确定出各种面层的抗变形效果。

| Abstract: | Cracks in block wall s due to hollow masonry expansion and shrinkage with humidity,can be controlled by controlling wall movement .Tests were conducted with four walls of the same dimen-sion s to establish the influence of climate,relative humidity,duration surfacing materials and water percentage on secondary shrinkage of block walls. |
| |
| Keywords: | block wall climate relative humanity surfacing materials secondary shrinkage shrink-age cracks water percentage expansion and shrinkage wall movement |
