蒸压灰砂砖砌体抗剪性能研究

Sh(?)r(?)rg stien(?)h of attcc(?)aved lime sand

通过对长沙地区大量的蒸压灰砂砖及灰砂空心砖抗剪强度的试验研究,其结果为:灰砂砖砌体抗剪强度高于粘土砖,也高于规范计算值。考察其原因,原料砂是影响其抗剪性能的主要因素,砌筑时砖的含水率是其重要因素。

The shear strength property of autoclaved lime sand brick in changsha has been studied for a number of tests. It shows that its strength is higher than that of clay brick and the value is higher than that specified of design specification too. There are two basic causes. A main factor affected is the material-sand in producing brick, and the other important is water capacity of brick in building.
