Mechanical Performance of Synthesized Bricks Made of Construction Wastes

采用建筑垃圾合成节能生态墙体在减少垃圾排放,促进生态环境保护中具有重要意义,提出基于荷载与应力联合控制约束的建筑垃圾合成的节能生态墙体受力性能分析模型。分析建筑垃圾合成的节能生态墙的应力结构模型,以软化系数和剪力传递系数为约束参量,采用非线性徐变承载应力拟合方法进行节能生态墙体受力结构拟合。建筑垃圾合成的节能生态墙体受力性能具有分线性徐变性,应力强度随着荷载的增大而增大,对受力性能测试结果准确,有效指导建筑垃圾合成的节能生态墙体承重梁设计。

It has great significance to use building waste to make synthesized energy saving ecological wall in order to reduce waste discharge and promoting ecological environment protection. Based on the combined control constraints of load and stress,the stress structure model of energy saving ecological wall is put forward in this paper,which is based on the combination of load and stress. The stress analysis model of energy conservation ecological wall based on the combination of load and stress is put forward. The softening coefficient and shear transfer coefficient are taken as constraint parameters. The test results show that the composite energy conservation ecological wall has linear creep behavior and the stress intensity increases with the increase of load.The test results of mechanical performance are accurate,which can effectively guide the design of energy saving ecological wall bearing beam for building waste synthesis.
