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.
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.
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.
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.
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.
