砌筑砂浆是砖混结构中的重要组成材料之一,对承重墙体力学性能的影响较大。引起砂浆强度变异的因素较多,在技术管理方面过去也缺乏统一标准,导致砂浆强度的离散性较大。试验表明,底砖含水率和垫底材料对砂浆试块强度也有一定的影响。 The masonry mortar is one of the important constituent materials in the brick-concrete structure, and has a great influence on the mechanical properties of the bearing wall. There are many factors that cause variation in the strength of mortar. In the past, there was also a lack of uniform standards in the management of the mortar, resulting in a greater dispersion of mortar strength. The test shows that the moisture content of the bottom brick and the bottom material have a certain influence on the strength of the mortar block.
