本文通过对灰砂砖及灰砂砖砌体的较系统的试验研究，得出了灰砂砖砌体的抗压强度、抗剪强度、弹性模量、泊桑比系数、含水率、吸水率及软化系数等。
This paper has arrived at the compressive strength, shear strength, modulus of elasticity, poisson's ratio, moisture content, water absorption and softening factor of lime-sand brick masonry.
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。
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.
