Abstract
The invention provides autoclaved aerated concrete masonry environment-friendly mortar and a preparation method of same and belongs to the technical field of cement. The mortar is composed of, by mass, 20-24% of 32.5-grade Portland cement, 2-4% of polypropylene anti-cracking fibers, 20-30% of quartz, 6-7.4% of redispersible latex powder, 0.8-1.2% of cellulose ether, 8-10% of an inorganic cementing material, 8-12% of gypsum, and 30-38% of waste earth residue. The materials are mixed in a null gravity mixer at the mixing rate being higher than 25 r/min. By adding quantitative inorganic cementing material, the mortar is reduced in shrinkage percentage and the aerated concrete masonry mortar is improved in heat insulation. By adding quantitative redispersible latex powder, the aerated concrete masonry mortar and special plastering mortar are improved in strength. By adding quantitative polypropylene anti-cracking fibers, the mortar is improved in anti-cracking effect. The addition amount of the waste earth residue is higher than 30%, so that the mortar utilizes wastes and is environment-friendly.
Description
Technical field
The invention belongs to cement technology field, build environmental protection mortar and preparation method by laying bricks or stones particularly to only having a kind of steam pressurized mixed earth.
Background technology
In the prior art, traditional masonry mortar and decorative mortar be not because matching with materials for wall, and hollowing and cracking easily occurs in wall plastering layer, even comes off, thus affects construction engineering quality；Self-strength not, drying shrinkage value bigger than normal, elastic modelling quantity is low, non-deformability is poor, porosity is high, and water absorption rate is the most also the defect of traditional masonry mortar and plastering mortar material.The existence of these problems just, have impact on the popularization of air-entrained concrete building block.Although strict construction technology management can reduce hollowing and the probability of crack generation to a certain extent, but to be inherently eliminated this common quality defect, it is necessary to solves the material integration problem of air-entrained concrete building block and supplementary material.How to strengthen the utilization of waste material simultaneously, make environmental protection with energy-conservation parallel, be our purpose of instantly studying.
Summary of the invention
It is an object of the invention to for existing above-mentioned problem, it is provided that a kind of performance is more preferable, and the steam pressurized mixed earth that waste residue utilization rate is high builds environmental protection mortar and preparation method by laying bricks or stones.
The purpose of the present invention can be realized by following technical proposal: a kind of steam pressurized mixed earth builds environmental protection mortar by laying bricks or stones, is made up of the material of following mass percent: 32.5 grades of portland cements 20%～24%, polypropylene anti-crack fiber 2%～4%, quartz 20%～30%, can be at dispersed latex powder 6%～7.4%, cellulose ether 0.8%～1.2%, inorganic coagulation material 8%～10%, Gypsum Fibrosum 8%～12%, roach slag 30%～38%.
