Plastering material for building wall body

Abstract

The invention discloses a plastering material for a building wall body. The plastering material comprises the following components in percentage by mass: 30 to 40 percent of cement, 40 to 50 percent of aggregates, 0.1 to 0.3 percent of water-retaining agent, 5 to 15 percent of gypsum, 0.3 to 0.5 percent of anti-cracking fibers, 3 to 7 percent of sierozem and 3 to 7 percent of coal ash, wherein the water-retaining agent is hydroxypropyl methyl cellulose or methylcellulose; and the anti-cracking fibers are polypropylene fibers or polyacrylonitrile fibers. When the plastering material for the building wall body is used for plastering, the plastering quality is stable, a plastering layer is bonded with a base layer firmly, and cracking and hollowing are avoided. The plastering material for the building wall body is convenient to construct, the labor productivity is improved, and the comprehensive cost is reduced; and when the plastering material is used, dry powder premix bags of a plant area are transported to construction sites, and the powder is stirred slightly by adding water, so that noise pollution and dust pollution which are caused by a large-scale stirring machine are avoided, and the plastering material achieves a positive effect on on-site civilized construction and environment friendliness.

Description

technical field [0001] The invention relates to a building material, in particular to a building wall plastering material. Background technique [0002] With the rapid development of my country's economy, the construction industry is also ushering in the peak of development. In the construction industry, the rough brick wall or cement wall formed by the building has a rough and inconsistent color, which seriously affects the practicality and appearance of the wall. In order to make the body of wall more practical and attractive in appearance, it is necessary to plaster the surface and apply putty on the body of wall to make the body of wall smooth and beautiful. Moreover, a layer of protection can be formed after the plastering of the building wall, so that the steel bars and concrete are not exposed, which can increase the service life of the building. [0003] In the above-mentioned plastering process, the traditional wall plastering material is made of cement and fine s...

Problems solved by technology

In the above-mentioned cement plastering mortar, an expansion agent is added to use the expansion effect to reduce the shrinkage of the plastering mortar during hardening, thereby effectively preventing the wall from cracking and bulging. However, the wall will become loose after adding the expansion agent. , resulting in low strength of the wall plastered with this cement plastering mortar

Due to the alkalinity of the internal curing agent, it will cause the alkalinity of the wall to increase. After the alkalinity of the wall increases, it will corrode the steel bars in the concrete structure, thereby affecting the quality and life of the building; and, in the follow-up In the process of scraping putty, it is necessary to neutralize the wall surface

If the alkalinity of the wall surface is high, it will increase the labor load and quality hidden dangers of the follow-up process
