设计有抗冻性要求的墙体时,砂浆应进行冻融试验,其抗冻性能应与墙体块材相同。砂浆强度等级应符合设计要求,若设计无具体要求,应参考相应标准。关于材料分类、技术性能、存放、搅拌等参见前期编制的预拌砂浆材料要求。
When designing a wall that is resistant to frost, the mortar should be freeze-thawed and its frost resistance should be the same as that of the wall block. Mortar strength grade should meet the design requirements, if the design without specific requirements, reference should be made to the appropriate standard. For material classification, technical performance, storage, mixing, etc. see the pre-prepared ready-mixed mortar material requirements.
