| 摘 要： | 再生混凝土砖是利用废弃混凝土作为骨料制作的一种砖,作为再生混凝土砖砌体抗震性能研究的基础,文中进行了18个不同砂浆强度的再生混凝土砖砌体的抗压性能试验。测试分析了各试件的承载力、变形和破坏过程,得到了再生混凝土砖砌体的抗压强度、弹性模量和泊松比。研究表明:再生混凝土砖砌体与普通黏土砖砌体相比,承载力略低,抗压强度退化略快,弹性模量和泊松比接近;随着砌筑砂浆强度的提高,再生混凝土砖砌体的承载力和变形能力提高,弹性模量增大。再生混凝土砖砌体可用于多层砌体房屋结构抗震设计。

| Abstract: | Recycled concrete brick is made of discarded concrete.As a basic study for the aseismic behavior of recycled concrete brick,the compression properties of 18 recycled concrete brick masonry specimens in different levels of mortar strength were tested.The load-bearing capacity,deformation and the failure process of each specimen were tested and analyzed.Then,the compression strength,elastic modulus and Poisson's ratio of recycled concrete brick were calculated.The research shows that,compared with common bric... |
