Low-cost self-leveling mortar

Abstract

The invention discloses a low-cost self-leveling mortar. The low-cost self-leveling mortar comprises the following components in proportions: 22-35% of quartz sand, 20-40% of modified fluorine gypsum, 18-25% of silicate cement, 4-18% of aluminate cement, 3-8% of zeolite powder, 4-8% of wollastonite powder, 8-18% of rapid hardening cement, 0.05-1.5% of de-foaming agent, 0.05-1% of water reducing agent, 0.05-0.3% of retarder, 0.01-2% of leveling agent, 0.1-2% of lignocelluloses, 0.1-2% of hydroxyethylcellulose, 0.1-2% of methylcellulose, 1-6% of casein and 0.02-0.06% of lithium carbonate. The low-cost self-leveling mortar has the advantages of high leveling property, wear resistance, stability, breaking strength and the like, good quality, high efficiency, low cost and helpfulness for energy saving, consumption reduction and environment improvement.

Description

technical field [0001] The invention relates to a low-cost self-leveling mortar, which belongs to building materials. Background technique [0002] With the rapid development of the national economy and the continuous improvement of people's living standards, the floors of some high-end buildings such as hospitals, gymnasiums, and museums use elastic flooring. , deeply loved by consumers, but the laying of these materials puts forward higher requirements for the leveling of the ground. In recent years, self-leveling mortar has been developed and produced successively, but its cost is high, and its bonding strength, self-leveling performance and quality stability are not ideal; in addition, my country's hi-IF industrial production capacity ranks first in the world, and a large number of them are in production every year The generated waste fluorine gypsum is harmful to the environment. At present, the development of comprehensive utilization of waste residue is unbalanced, a...

Problems solved by technology

In recent years, self-leveling mortar has been developed and produced successively, but its cost is high, and its bonding strength, self-leveling performance and quality stability are not ideal; in addition, my country's hi-IF industrial production capacity ranks first in the world, and a large number of them are in production every year The generated waste fluorine gypsum is more harmful to the environment

At present, the development of comprehensive utilization of waste residue is unbalanced, and fluorine gypsum waste residue has not been utilized; in recent years, the building materials industry has developed rapidly, but it consumes a lot of resources, and many industrial wastes have not been comprehensively utilized.
