摘要
对不同砌筑灰缝厚度的墙体进行压力破坏试验,研究灰缝对墙体力学性能的影响,结果表明,随着灰缝厚度的增加,墙体的抗压强度减小,并通过线性回归分析得到规律方程;通过传热分析,对包含1个垂直灰缝和1个水平灰缝的砌筑单元的传热速率进行计算,推导出砌筑单元的传热速率与灰缝厚度之间呈正比函数关系式,对墙体性能的提高具有理论指导意义。
The influence of joints on mechanical properties of the walls is studied by the destruction tests under pressure. As the thickness of the joints increased,the compressive strength of the wails decreased,which had been calculated by linear regres- sion analysis. We calculated＇ the rate of heat transfer of a single masonry unit,which included a vertical mortar joint and a hori- zontal mortar joint. Subsequently infers the proportional function between the rate of heat transfer of a single masonry unit and the thickness of joints. These works has guiding significance in improving the properties of wall.
