Problems solved by technology

[0005] With the improvement of people's living standards, the requirements for building quality are getting higher and higher. The existing mortar has poor anti-seismic effect, large shrinkage, low cohesion, poor durability, easy cracking and dust explosion, which leads to poor project quality. The stability and strength cannot meet the requirements, which will have an adverse effect on the service life of the building and even bring safety hazards

Abstract

The invention discloses a composite mortar with an anti-seismic function, which is prepared from, by weight, 50-65 parts of Portland cement, 35-45 parts of gypsum powder, 30-45 parts of slag powder, 25-35 parts of quartz sand, 25-30 parts of latex powder, 18-25 parts of slag powder, 15-25 parts of sepiolite, 6-10 parts of perlite, 5-10 parts of ceramic microbeads, 6-10 parts of wood fibers, 8-10 parts of PP fibers, 4-7 parts of polypropylene fiber, 5-10 parts of lithium bentonite, 7-10 parts of a water reducer, 8-12 parts of a binder, 3-5 parts of an expander, 2-4 parts of a defoamer, and 2-4parts of polyacrylamide. The composite mortar has excellent anti-seismic performance, saves resources, reduces the production cost, has the advantages of high strength, good uniformity, good bonding effect and good anti-cracking performance, and is beneficial to improving the quality of buildings.

Description

technical field [0001] The invention relates to the technical field of mortar, in particular to a composite mortar with anti-seismic function. Background technique [0002] Mortar refers to the bonding substance used in building bricks. It is composed of a certain proportion of sand and cementing materials (cement, lime paste, clay, etc.) and water. It is also called mortar or mortar. As an important building material, mortar is very useful extensive; [0003] According to the composition materials, ordinary mortar can be divided into lime mortar, cement mortar and mixed mortar. Lime mortar is made of lime paste, sand and water in a certain proportion. It is generally used for masonry and plastering that do not require high strength and are not subject to moisture. Ash layer, cement mortar is made of cement, sand and water according to a certain ratio, generally used for masonry, wall or ground in wet environment or water, etc. The mixed mortar is properly blended in cement...
