Plastering mortar is mainly used for the anti crack protective layer outside the thermal insulation layer of benzene thin plastering insulation system. Therefore, it is also called polymer plastering anti cracking mortar. Plastering mortar is applied on the surface of buildings to protect the base and meet the requirements of use. The main classification of plastering mortar is as follows.

(1)普通抹面砂浆

(1) Common plastering mortar

普通抹面砂浆是建筑工程中使用量的抹灰砂浆。普通抹面砂浆的功能主要是保护墙体和地面不受到风雨和有害杂质的侵蚀，提高墙体和地面的防潮性、防腐蚀性、抗风化性能，增加墙体和地面的耐久性。同时，可以使建筑达到表面平整和美观的效果。

Ordinary plastering mortar is the most widely used plastering mortar in construction engineering. The main function of common plastering mortar is to protect the wall and ground from the erosion of wind and rain and harmful impurities, improve the moisture resistance, corrosion resistance and weathering resistance of walls and floors, and increase the durability of walls and floors. At the same time, it can make the building surface smooth and beautiful.

(2)防水砂浆

(2) Waterproof mortar

防水砂浆是一种抗渗性高的砂浆。防水砂浆层又叫做刚性防水层，适用于具有一定刚度的混凝土或者是砖石砌体的表面，对于变形比较大或者是可能发生不均匀沉陷的建筑物，都不宜采用这种刚性防水层。

Waterproof mortar is a kind of mortar with high impermeability. Waterproof mortar layer is also called rigid waterproof layer, which is suitable for the surface of concrete or masonry with certain rigidity. It is not suitable to use this kind of rigid waterproof layer for buildings with large deformation or uneven settlement.

(3)保温砂浆

(3) Thermal insulation mortar

保温砂浆又叫做绝热砂浆，是采用石灰、水泥和石膏等胶凝材料和膨胀珍珠岩或者是膨胀蛭石、陶砂等轻质的多孔骨料按一定的比例配合制成的砂浆。保温砂浆具有保温隔热、轻质、吸声等等的性能，可以用于屋面保温层、保温墙壁和供热管道保温层等地方。

Thermal insulation mortar, also known as thermal insulation mortar, is made of lime, cement, gypsum and other cementitious materials and expanded perlite or expanded vermiculite, pottery sand and other lightweight porous aggregate in a certain proportion. Thermal insulation mortar has the properties of heat insulation, light weight, sound absorption and so on. It can be used in roof insulation layer, thermal insulation wall and heat supply pipeline insulation layer.

(4)吸声砂浆

(4) Sound absorbing mortar

一般的绝热砂浆是由轻质的多孔骨料制作而成的，具有吸声性能。同时，可以用石膏、水泥、砂、锯末按体积比率配制成吸声砂浆，或者在石灰、石膏砂浆中掺进玻璃纤维和矿棉等松软纤维的材料制作而成。吸声砂浆主要是用于室内的墙壁和平顶。

General thermal insulation mortar is made of lightweight porous aggregate and has sound absorption performance. At the same time, it can be made of gypsum, cement, sand and sawdust according to the volume ratio, or mixed with glass fiber and mineral wool and other soft fiber materials in lime and gypsum mortar. Sound absorbing mortar is mainly used for interior walls and flat roofs.

(5)耐酸砂浆

(5) Acid resistant mortar

用硅酸钠和氟硅酸钠拌制成耐酸砂浆，有时候也可以掺进石英岩、花岗岩、铸石等等粉状的细骨料。等到水玻璃硬化之后，具有很好的耐酸性能。耐酸砂浆多用于作为衬砌的材料、耐酸地面和耐酸容器的内壁防护层。

Acid resistant mortar is made by mixing sodium silicate and sodium fluorosilicate. Sometimes it can be mixed with fine powder aggregate such as quartzite, granite and cast stone. After the water glass hardens, it has good acid resistance. Acid resistant mortar is usually used as lining material, acid resistant floor and inner wall protective layer of acid resistant container.

(6)装饰砂浆

(6) Decorative mortar

装饰砂浆是直接用于建筑物内外表面的，以增强建筑物的装饰艺术性为主要目的抹面砂浆。装饰砂浆是常常用到的装饰手段之一。装饰砂浆的底层和中层抹灰和普通抹面砂浆是基本相同的，主要是装饰砂浆的面层。选用具有一定颜色的胶凝材料和骨料，还要采用某种特殊的操作工艺，使表面表现出不同的色彩、线条和花纹等装饰的效果。

Decorative mortar is directly used for the internal and external surface of buildings, to enhance the decorative art of buildings as the main purpose of plastering mortar. Decorative mortar is one of the decorative means often used. The bottom and middle layers of decorative mortar are basically the same as ordinary plastering mortar, mainly the surface layer of decorative mortar. The selection of cementitious materials and aggregates with a certain color, as well as some special operation technology, can make the surface show different decorative effects such as colors, lines and patterns.
