本研究的目的是,在山西太原地区冬季气温条件下,根据砌体强度的要求,确定用那一种砂浆(水泥砂浆、混合砂浆、白灰砂浆)、那一种水泥(硅酸盐、矿渣)、那一种砂(豆罗砂、太原产黑砂)、邢一种盐类(氯化钠、氯化钙)较好;砌筑质量对砌体强度影响的程度;不同砂浆列砌体变形的影响等。通过45个标准砌体的试验分析,证明:混合砂浆远远优于水泥砂浆,白灰砂浆也可应用;硅酸盐水泥较矿渣水泥为优越;砌筑质量对砌体强度有显著的影响;混台砂浆砌体的变形较水泥砂浆的为大,白灰砂浆的最大:不同的盐类和砂浆对砌体强度的影响,没有显著的差别。我们初步认为:在太原地区的冬季气候条件下,采用白灰砂浆或混合砂浆即可,不需要将砂浆标号提高一极,因此可以节约大量水泥。
The purpose of this study is to determine which type of mortar (cement mortar, mortar, mortar) and cement (silicate, slag) are used according to the requirements of masonry strength in winter conditions in Taiyuan, Shanxi. , a kind of sand (bean boring sand, Taiyuan black sand), Xing a kind of salt (sodium chloride, calcium chloride) is better; the degree of the influence of masonry quality on masonry strength; different masonry column masonry deformation The impact and so on. Through the test analysis of 45 standard masonry structures, it is proved that the mixed mortar is far better than the cement mortar, and the white-ash mortar can also be applied; the Portland cement is superior to the slag cement; the masonry quality has a significant influence on the masonry strength; The deformation of the mortar masonry is greater than that of the cement mortar, and the maximum of the lime mortar: the influence of different salts and mortar on the masonry strength, and there is no significant difference. We tentatively believe that: in the winter climate in Taiyuan, white mortar or mortar can be used, and there is no need to increase the number of mortar marks to one pole, thus saving a lot of cement.
