Abstract
The present invention discloses a kind of autoclave aerated concrete building block special masonry mortar, belongs to building material field.The present invention is obtained by the raw material of following parts by weight：0.1 part~1.5 parts of 80 parts~85 parts of sand, 12 parts~15 parts of cement, 10 parts~30 parts of flyash and additive.The present invention passes through to add and limit the granular size of flyash, and by adding and limit the grain composition structure of raw material sand, and the additive of collocation specific components, so as to have excellent water retention, shrinkage factor, adhesion strength, compression strength and delamination degree, so that when being built by laying bricks or stones to autoclave aerated concrete building block, effectively prevent masonry and the phenomenon such as crack and wall contraction sinking occur.
Description
Technical field
The invention belongs to building material field, and in particular to what a kind of autoclave aerated concrete building block was used when building by laying bricks or stones
Mortar.
Background technology
At present, the most or traditional masonry mortar of autoclave aerated concrete building block is used when building by laying bricks or stones mortar, i.e.,
The mortar being mixed by cement and sand.However, because autoclave aerated concrete building block is present, self-strength is not high, dry contraction
The problem that value is big, non-deformability is poor, porosity is high, water absorption rate is big etc., and traditional masonry mortar also generally existing water-retaining property
The not enough problem of difference, adhesion strength, so as to cause the combination of the two to easily cause bond structure crack, reduces bearing capacity of wall body, wall
Shrink, have a strong impact on construction engineering quality, hinder the popularization and application of autoclave aerated concrete building block.Therefore, in order to more preferable
Popularization autoclave aerated concrete building block application, it is necessary to seek it is a kind of match with it build dedicated mortar by laying bricks or stones.
The content of the invention
The present invention provides a kind of autoclave aerated concrete building block special masonry mortar, and the masonry mortar solves to be built by laying bricks or stones because of tradition
Mortar is mismatched with autoclave aerated concrete building block and causes bond structure crack, reduces bearing capacity of wall body, and wall shrinks asking for sinking
Topic.
In order to solve the above technical problems, the technical solution adopted in the present invention is：
It is obtained by the raw material of following parts by weight：
0.1 part~1.5 parts of 80 parts~85 parts of sand, 12 parts~15 parts of cement, 10 parts~30 parts of flyash and additive；
Wherein, the sand refers to the sand with following grain composition structure：
More than 9.5mm mesh screens： 0%；
More than 4.75mm mesh screens：10%~0%；
More than 2.36mm mesh screens：25%~5%；
More than 1.18mm mesh screens：50%~10%；
More than 600 μm of mesh screens：71%~41%；
More than 300 μm of mesh screens：92%~70%；
More than 150 μm of mesh screens：100%~80%；
The flyash refers to the remaining flyash less than 25% of 0.045mm mesh screens；
The additive refers to the mixture being made up of cellulose ether, amylase, air entraining agent, rubber powder, sodium chloride.
In above-mentioned technical proposal, more specifically technical scheme can also be：The bulk density of the additive is 400g/
cm3~450g/cm3。
By adopting the above-described technical solution, the present invention compared with prior art, has an advantageous effect in that：
1. the present invention passes through to add and limit the granular size of flyash, so as to effectively reduce the drying shrinkage of mortar, subtracts
The contraction of few wall.
2. the present invention is by adding and limits the grain composition structure of raw material sand, and the additional of specific components of arranging in pairs or groups
Agent, so as to reduce the delamination degree of mortar, improves its workability and adhesion strength, it is ensured that wall occurs without crack, the phenomenon for declining.
