Pre-mixed mortar needs to stop screening and drying in the process of processing, so the sand in mortar is almost free of impurities such as mud, which is comparable to the requirements of specifications and can ensure the accuracy of measurement. And it is a new type of building materials developed in recent years in our country, which is produced by specialized manufacturers and used in the construction of various mortar mixtures.

　　还有重要的一点是，预拌砂浆由搅拌站提供预先拌制好的（未加水）干粉料提供应工地，运用时加水搅拌即可。质量好，本钱高。而抹灰砂浆则是通常分普通抹灰和装饰抹灰两大类，抹灰砂浆的品种依据抹灰砂浆功用的不同，抹灰砂浆分为普通抹灰砂浆、装饰抹灰砂浆和特种抹灰砂浆。

　　Another important point is that the ready-mixed mortar is provided by the mixing station with pre-mixed (without water) dry powder to provide the site, when used, water mixing can be added. Good quality and high cost. The plastering mortar is usually divided into ordinary plastering and decorative plastering. According to the different functions of plastering mortar, plastering mortar is divided into ordinary plastering mortar, decorative plastering mortar and special plastering mortar.

　　通常对抹灰砂浆的强度请求并不很高，普通采用中等强度等级的水泥就可以满足请求。抹灰砂浆强度不宜超越基体资料强度两个强度等级。粘贴饰面砖的内外墙，中层抹灰砂浆的强度不低于M15，且优先选用水泥抹灰砂浆。

　　Usually, the strength requirement of plastering mortar is not very high, and the requirement can be met by using medium strength cement. The strength of plastering mortar should not exceed two strength grades of matrix material strength. The strength of plastering mortar in the middle layer is not less than M15, and the cement plastering mortar is preferred.

　　所以，预拌砂浆和抹灰砂浆到底哪个好用些呢，这个也没有固定的答案，还是要依据客户的需求，各有各的益处，只需是对本人有利的，都是好的。后，给大家引荐高新开发区巨野河福华建材厂，一家济南抹面砂浆公司。本文来源：https://www.jnfhjc.com
