在砌筑砂浆中掺拌和水重量3～5%食盐(氯化钠)做为抗冻促凝剂(又称掺盐砂浆),进行砌筑工程冬季施工的方法已有二十多年的历史了。多少年来,我们按照施工规范的有关规定,进行砌体工程冬季施工,当大气平均温度低于-10℃时,则按照GBJ14-66砌体工程施工规范第110条“对砌筑承重砌体的砂浆标号,按常温施工时提高
Mixing and mixing water in masonry mortar weight 3 to 5% salt (sodium chloride) as anti-freezing and coagulant (also called salt-mixed mortar), the method of winter construction of masonry has been more than 20 years Now. For many years, we carried out winter construction of masonry projects in accordance with the relevant provisions of the construction regulations. When the average atmospheric temperature is lower than -10°C, we shall comply with Article 110 of the Code for the Construction of Masonry Buildings GBJ14-66, which is for masonry bearing masonry. Mortar marking, improved at room temperature
