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)普通抹面砂漿

(1) Common plastering mortar

普通抹面砂漿是建筑工程中使用量的抹灰砂漿。普通抹面砂漿的功能主要是保護墻體和地面不受到風雨和有害雜質的侵蝕，提高墻體和地面的防潮性、防腐蝕性、抗風化性能，增加墻體和地面的耐久性。同時，可以使建筑達到表面平整和美觀的效果。

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)防水砂漿

(2) Waterproof mortar

防水砂漿是一種抗滲性高的砂漿。防水砂漿層又叫做剛性防水層，適用于具有一定剛度的混凝土或者是磚石砌體的表面，對于變形比較大或者是可能發生不均勻沉陷的建筑物，都不宜采用這種剛性防水層。

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)保溫砂漿

(3) Thermal insulation mortar

保溫砂漿又叫做絕熱砂漿，是采用石灰、水泥和石膏等膠凝材料和膨脹珍珠巖或者是膨脹蛭石、陶砂等輕質的多孔骨料按一定的比例配合制成的砂漿。保溫砂漿具有保溫隔熱、輕質、吸聲等等的性能，可以用于屋面保溫層、保溫墻壁和供熱管道保溫層等地方。

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)吸聲砂漿

(4) Sound absorbing mortar

一般的絕熱砂漿是由輕質的多孔骨料制作而成的，具有吸聲性能。同時，可以用石膏、水泥、砂、鋸末按體積比率配制成吸聲砂漿，或者在石灰、石膏砂漿中摻進玻璃纖維和礦棉等松軟纖維的材料制作而成。吸聲砂漿主要是用于室內的墻壁和平頂。

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)耐酸砂漿

(5) Acid resistant mortar

用硅酸鈉和氟硅酸鈉拌制成耐酸砂漿，有時候也可以摻進石英巖、花崗巖、鑄石等等粉狀的細骨料。等到水玻璃硬化之后，具有很好的耐酸性能。耐酸砂漿多用于作為襯砌的材料、耐酸地面和耐酸容器的內壁防護層。

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)裝飾砂漿

(6) Decorative mortar

裝飾砂漿是直接用于建筑物內外表面的，以增強建筑物的裝飾藝術性為主要目的抹面砂漿。裝飾砂漿是常常用到的裝飾手段之一。裝飾砂漿的底層和中層抹灰和普通抹面砂漿是基本相同的，主要是裝飾砂漿的面層。選用具有一定顏色的膠凝材料和骨料，還要采用某種特殊的操作工藝，使表面表現出不同的色彩、線條和花紋等裝飾的效果。

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.
