Abstract

The invention relates to the technical field of building materials, and particularly discloses environment-friendly anti-cracking dry-mixed plastering mortar. The environment-friendly anti-cracking dry-mixed plastering mortar is prepared from the following raw materials in parts by weight: 40 to 70 parts of clinker-free ecological cementing materials, 40 to 70 parts of superfine slag powder, 50 to 90 parts of active fly ash, 5 to 20 parts of lithium silicate powder, 5 to 15 parts of anti-cracking fibers, 20 to 50 parts of hollow microspheres, 700 to 800 parts of sand, 0.2 to 0.5 part of HPMC (Hydroxy Propyl Methyl Cellulose), 0.2 to 0.8 part of thixotropic agents, 0.2 to 0.8 part of water reducing agents and 5 to 20 parts of ethylene-vinyl acetate. The plastering mortar has the advantages that slag, coal cinder and other waste solids are processed into the plastering mortar, the plastering mortar has the advantages of being high in bonding strength, good in water-retaining property, smooth in construction, free of hollowing, free of cracking and free of powder falling, the mortar material can be used after being conveyed to a construction site and stirred with water during use, and labor and materials are saved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an environment-friendly anti-cracking dry-mix plastering mortar. Background technique [0002] Among building materials, mortar is the most important building material. More than one third of the total cement produced in my country is used to configure mortar. Most traditional mortars are configured and stirred on site, but they are labor-intensive, low in construction efficiency, pollute the surrounding environment, and inaccurate on-site configuration and measurement. In response to these problems, after commercial concrete, commercial mortar (ie dry-mixed mortar) has appeared on the market. Dry-mixed plastering mortar is made up of cement, admixtures, dry sand, admixtures and modified auxiliaries evenly mixed. It has the advantages of high bonding strength, good water retention, and smooth construction. It can be constructed and is a new type of building material...
