砌筑砂浆的强度是影响砌体工程质量的重要因素,在施工中一些施工人员往往忽视了砌筑砂浆强度这一重要环节,致使砌筑砂浆强度忽高忽低,波动很大,严重影响了砌体结构的正常使用年限和抗震性能,一般砌筑砂浆强度每降低一级,砌体的抗压强度就会比正常设计值降低20%左右,那么影响砌筑砂浆强度不稳定的因素有哪些呢?主要有以下几点:
The strength of masonry mortar is an important factor influencing the quality of masonry projects. In construction, some construction workers often overlook the important part of masonry mortar strength, which causes the strength of masonry mortar to fluctuate and fluctuate greatly, which seriously affects For the normal service life and seismic performance of masonry structures, the strength of masonry generally decreases by 20% compared with the normal design value when the strength of masonry mortar is reduced by one level. What factors affect the instability of masonry mortar strength? What are the main points?
