Problems solved by technology

[0014] However, the color decorative mortar currently on the market has problems such as fading and cracking, and has strict construction requirements, especially under some special construction conditions, such as short construction time and high construction temperature, resulting in the decoration on the wall. The surface mortar loses water too quickly and is easy to crack, which affects the reinforcement effect and overall appearance of the wall

Abstract

The invention relates to a building material, and particularly relates to a basalt fiber-reinforced anti-cracking facing mortar. The basalt fiber-reinforced anti-cracking facing mortar comprises the following components in parts by weight: 19-24 parts of cement, 51-62 parts of silica sand, and 0.1-0.5 part of basalt chopped fiber, wherein the monofilament diameter of the basalt chopped fiber is 9-18mu m, and the chopping length of the basalt chopped fiber is 3-15mm. In the basalt fiber-reinforced anti-cracking facing mortar, the adopted basalt chopped fiber has good acid-base resisting performance, can be effectively mixed into Portland cement in the facing mortar; the reinforced facing mortar has the advantages of good crack resistance, good weather resistance, good ultraviolet ray resistance, uniform color and the like, is durable, can be well combined with various inorganic basement materials, is good in coating compactness, and can be applied to the building fields of interior and exterior wall decoration and the like.

Description

technical field [0001] The invention relates to a building material, in particular to a basalt fiber reinforced crack-resistant facing mortar. Background technique [0002] Finishing mortar refers to a kind of physical mixing of dried and screened aggregate (such as quartz sand), inorganic cementitious material (such as white cement), additives (such as polymer, inorganic pigment) and so on in a certain proportion. Granular or powdery, transported to the construction site in bags or in bulk, and can be used directly after mixing with water. There are many colors of facing mortar, and it is generally used on the surface of the wall for interior and exterior wall decoration. It is suitable for the exterior wall decoration of high-end real estate and villas and the final decoration layer of the entertainment place and restaurant lamp personalized wall exterior insulation system. [0003] Compared with conventional facing materials, facing mortar has the following advantages: ...
