Anti-cracking plastering mortar

Abstract

The invention belongs to the technical field of building materials and construction, and particularly relates to anti-cracking plastering mortar.The anti-cracking plastering mortar is prepared from, by weight, 200-220 parts of ordinary Portland cement, 780-800 parts of engineering sand, 1-1.5 parts of polypropylene fibers and 0.5-0.6 part of ordinary mortar additive.The anti-cracking plastering mortar has a good application property and water-retaining property, and can be widely applied to building walls.Compared with traditional products or existing products, a three-dimensional disordered distribution net bearing function can be formed in concrete, and microcracks formed at the preliminary hardening stage of a cement product are blocked in the development process and can hardly further develop.Therefore, the breaking tenacity of the cement product can be improved, the anti-cracking and anti-seepage performance of the cement product is improved, and the anti-cracking plastering mortar is a novel ideal anti-cracking, anti-seepage, abrasion resisting and heat preserving material in the mortar and concrete work.

Description

technical field [0001] The invention belongs to the technical field of building materials and construction, and in particular relates to a crack-resistant plastering mortar. Background technique [0002] With the continuous advancement of the reform of building wall materials in my country, a large number of new wall materials have been widely used, and a wall material structure system dominated by wall blocks has been formed. The wall block has strong water absorption and large shrinkage, and the mixing water in the mortar is quickly absorbed by the wall material, while the traditional plastering mortar has poor construction performance, water retention, low bonding strength, cracking, and powder loss. Such problems will seriously affect the quality of the building, so the traditional plastering mortar can no longer meet the existing wall plastering construction requirements. With the rapid development of the market economy and the continuous improvement of people's materia...

AI Technical Summary

Problems solved by technology

The wall block has strong water absorption and large shrinkage, and the mixing water in the mortar is quickly absorbed by the wall material, while the traditional plastering mortar has poor construction performance, water retention, low bonding strength, cracking, and powder loss. And other problems will seriously affect the quality of the building, so the traditional plastering mortar can no longer meet the existing wall plastering construction requirements. With the rapid development of the market economy and the continuous improvement of people's material living standards, residential construction has maintained a rapid development. At the same time, people are more and more advocating the comfort, upscale and elegance of the living environment, and the majority of residents have to carry out different degrees of decoration before moving into their new homes to create a beautiful and comfortable living environment. Driven the upsurge of decoration and modernization of indoor facilities

[0003] Because the traditional plastering mortar has poor workability on various blocks, has low bonding strength with the blocks and is easy to crack after drying, which seriously affects the building quality. Therefore, there is an urgent need for a mechanically constructable, crack-resistant Plastering mortar with good bonding strength and low drying shrinkage can improve the crack resistance of the overall wall surface and avoid various degrees of cracking
