Abstract

The invention relates to a cement mortar used for masonry. The cement mortar comprises the following raw materials in parts by weight: 8-24 parts of zinc sulfide, 20-25 parts of calcium carbonate, 12-18 parts of porcelain clay powder, 11-17 parts of hydroxymethyl cellulose, 4-8 parts of 2-hydroxy propylamine, 3-6 parts of sodium sulfate, 9-14 parts of gypsum, 0.3-0.9 parts of methyl acrylate, 40-55 parts of Portland cement, 15-22 parts of quartz sand, 4-7 parts of a water reducer, 1.2-2.3 parts of methyl cellulose, 1-2 parts of sodium acetate, 0.5-2.5 parts of gamma-trimethoxysilylpropanethiol, 2.5-4.5 parts of silicon dioxide, 1-4 parts of rosin, and 2-5 parts of alum. The cement mortar has the beneficial effects that the mortar water retention is increased, freeze thaw capability is strong, adhesion stress is strong, engineering quality is greatly increased, and the preparation technology is simple.

Description

technical field [0001] The invention relates to a cement mortar for masonry. Background technique [0002] In home decoration, cement mortar is used in the paste of floor tiles, wall tiles and masonry. It can not only enhance the adsorption capacity of the surface material and the base layer, but also protect the internal structure. At the same time, it can be used as a leveling layer for the rough surface of the building. Therefore, in the decoration project, cement mortar is an indispensable material. Cement is the main cementing material of masonry mortar, but the traditional cement mortar used for masonry has poor bonding performance between mortar and block, which leads to more cracking and leakage of masonry in the project, shortening the use of life. Contents of the invention [0003] In view of the deficiencies in the prior art, the problem to be solved by the present invention is to provide a cement mortar for masonry, which improves the water retention of the...
