Problems solved by technology

Now the traditional cement mortar can no longer meet the needs of use, because when the traditional cement mortar is used as an exterior wall building, it will be more prone to problems such as hollowing, cracking, fluffing, and creases, and it is heavy as a wall surface building material, which increases The overall weight of the building is likely to affect the overall stability of the building

Abstract

The invention discloses cement mortar. The cement mortar is prepared from the following raw materials in parts by weight: 12 to 25 parts of perlite, 20 to 35 parts of portland cement, 4 to 8 parts of expanded vermiculite, 5 to 7 parts of latex powder, 1 to 1.5 parts of sulfomethylated phenolic resin, 2 to 4 parts of sodium sulfate, 6 to 9 parts of coke, 8 to 16 parts of tricalcium aluminate, 12 to 22 parts of lysine, 18 to 32 parts of vitrified microspheres, 10 to 17 parts of polyacrylonitrile fibers, 4 to 6 parts of sodium tripolyphosphate, 7 to 9 parts of magnesium oxide, 2 to 4 parts of barium metaborate and 3 to 7 parts of bentonite. The cement mortar disclosed by the invention has the beneficial effects of excellent dimensional stability, low elongation, improved strength, lower construction cost, and no deformation, damage or crack.

Description

technical field [0001] The invention relates to a cement mortar. Background technique [0002] China is the country with the largest amount of housing construction in the world, and the total amount of building materials required is also the largest in the world. China's construction mortar has the fastest development and is also the country with the largest application volume, so its requirements are becoming more and more stringent. Now the traditional cement mortar can no longer meet the needs of use, because when the traditional cement mortar is used as an exterior wall building, it will be more prone to problems such as hollowing, cracking, fluffing, and creases, and it is heavy as a wall surface building material, which increases The overall weight of the building is likely to affect the overall stability of the building. Contents of the invention [0003] In view of the deficiencies of the prior art, the problem to be solved by the present invention is to provide ...
