Pre-mixed mortar needs to be screened and dried in the process of processing, so the mortar contains almost no impurities such as mud, which meets the standard requirements and can ensure the accuracy of measurement. It is a new type of building material developed in recent years in China, which is produced by professional manufacturers and used in various kinds of mortar mixtures in construction projects.

　　还有一点很重要，拌和砂浆由拌和站事先提供拌和好(不加水)干粉提供工地，使用时加水拌和即可。质量好，成本高。而抹灰砂浆通常分为普通抹灰和装饰抹灰两大类，根据抹灰砂浆功能的不同类型，抹灰砂浆可分为普通抹灰砂浆、装饰抹灰砂浆和特殊抹灰砂浆。

　　Another important point is that the mixing mortar is provided by the mixing station in advance to mix well (without water) dry powder to provide the site, when used, it can be mixed with water. Good quality and high cost. The plastering mortar is usually divided into ordinary plastering and decorative plastering. According to the different types of plastering mortar function, plastering mortar can be divided into ordinary plastering mortar, decorative plastering mortar and special plastering mortar.

　　一般抹灰砂浆的强度要求不是很高，中等强度等级的水泥可以满足要求。抹灰砂浆的强度不应超过基材的两个强度等级。贴面砖内外墙，中层抹灰砂浆强度不低于M15，水泥抹灰砂浆优先。

　　Generally, the strength requirement of plastering mortar is not very high, and the cement of medium strength grade can meet the requirement. The strength of plastering mortar should not exceed the two strength grades of the base material. The strength of plastering mortar in the middle layer is not less than M15, and the cement plastering mortar is preferred.

　　在施工过程中，采用预拌砂浆提高了砂浆的强度，给抹灰技术和抹灰基质的界面处理带来了一些新的变化。采用低强度砂浆可提高抹灰效率，减少抹灰层空鼓开裂。

　　In the construction process, the use of ready-mixed mortar improves the strength of mortar, bringing some new changes to the plastering technology and the interface treatment of plastering matrix. Using low strength mortar can improve plastering efficiency and reduce hollow cracking of plastering layer.

　　由于相关标准对预拌砂浆的强度没有质量要求，现场施工时常要配制低强度抹灰砂浆，相当数量的工程砂浆强度不能满足工程的要求。由于砂浆抹灰层充满粉料，一拉就会脱落，砂浆抹灰工程的质量无法满足装饰要求。冬季砂浆强度增长缓慢，这种情况尤为明显，客户投诉较多，现拌砂浆对砂浆强度已有规定。预拌砂浆的强度增加后,砂浆抹层的刚度增加,和砂浆的拉伸应力抹一层一层抹接口治疗增加,抹的治疗质量必须相应改善,基础表面和建设必须进行严格按照抹建设法规,以确保施工质量。

　　Because there is no quality requirement for the strength of ready-mixed mortar in relevant standards, low-strength plastering mortar is often prepared in site construction, and a considerable amount of Engineering mortar strength can not meet the engineering requirements. Because the mortar plastering layer is full of powder, it will fall off when pulled, and the quality of mortar plastering engineering can not meet the decorative requirements. In winter, the strength of mortar increases slowly, which is particularly evident. There are many complaints from customers, and the strength of mortar has been regulated by ready-mixed mortar. When the strength of ready-mixed mortar increases, the stiffness of the mortar coating increases, and the treatment of the interface layer by layer with the tensile stress of the mortar increases. The treatment quality of the plastering must be improved accordingly. The foundation surface and construction must be strictly in accordance with the construction regulations to ensure the construction quality.
