The cement is the main cementing material of the masonry mortar, but the traditional cement mortar for masonry has poor bonding performance between mortar and blocks, so that more masonry cracking and leakage conditions occur in the engineering, and the service life is shortened.
In patent document CN106186910A, a cement mortar for masonry is disclosed, which is made from the following raw materials in parts by weight: 8-24 parts of zinc sulfide, 20-25 parts of calcium carbonate, 12-18 parts of china clay powder, 11-17 parts of hydroxymethyl cellulose, 4-8 parts of 2-hydroxypropyl amine, 3-6 parts of sodium sulfate, 9-14 parts of gypsum, 0.3-0.9 part of methyl acrylate, 40-55 parts of silicate cement, 15-22 parts of quartz sand, 4-7 parts of water reducing agent, 1.2-2.3 parts of methyl cellulose, 1-2 parts of sodium acetate, 0.5-2.5 parts of gamma-mercaptopropyl trimethoxy silane, 2.5-4.5 parts of silicon dioxide, 1-4 parts of rosin and 2-5 parts of alum. The beneficial effects of the invention are: the cement mortar for building disclosed by the invention has the advantages of improving the water retention property of the mortar, stronger freeze-thaw resistance and strong binding power, greatly improves the engineering quality and is simple in preparation process.
However, the above cement mortar is insufficient in impact strength after setting, is liable to deform after a long time, and is insufficient in water resistance.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides the cement mortar for the decoration engineering construction and the preparation method thereof, which have the advantages of high strength, fire resistance, high temperature resistance, long service time and better waterproof effect.
The invention provides cement mortar for decorative engineering construction, which comprises the following raw materials in parts by weight:
200 parts of cement 180-grade sand 320 parts, 40-50 parts of steel fiber, 20-30 parts of titanium fiber, 35-40 parts of polyethylene terephthalate fiber, 10-14 parts of silicon carbide, 15-20 parts of calcium carbonate, 60-70 parts of fly ash, 3-5 parts of hydroxypropyl methyl cellulose, 8-10 parts of redispersible latex powder, 2-4 parts of early strength admixture, 1-3 parts of retarder, 2-3 parts of defoaming agent, 1-2 parts of antirust agent, 2-4 parts of organic silicon waterproof agent, 1-2 parts of magnesium aluminum silicate thixotropic lubricant and 150 parts of water 130-grade sand.
