Abstract

The present invention relates to a kind of aerated blocks thin layer motar; comprise by weight percentage, including following component: portland cement 30～45%, graded sand and stone 40～55%, glass bead 3～15%, inorganic bentonite 0.5%, wood fibre 0.1%, water reducer 0.05%, cellulose ether 0.02%, starch ether 0.01%；Invention not only improves the workability of mortar, and there is preferable water-retaining property, heat insulating ability and crack resistance, and the thickness of mortar can be less than 5mm, thus improve efficiency of construction, it is to avoid the hollowing of coat of plaster, crack phenomenon.

Description

A kind of aerated blocks thin layer motar

Technical field

The present invention relates to building material field, refer in particular to a kind of aerated blocks thin layer motar.

Background technology

Aerated blocks is a kind of light porous New Building Materials, has unit weight light, and high insulating efficiency is high, and sound-absorbing is good and can add The advantages such as work, general load-bearing or non bearing structure in industry with civil buildings, become an important set of New Building Materials Become part；But traditional motar application property on aerated blocks is poor, and the thickness of motar less than 5mm time, not only with add Air parcel adhesion strength is low and the most easily ftractures, and has a strong impact on construction quality.

Summary of the invention

The invention aims to overcome the deficiencies in the prior art to provide a kind of aerated blocks thin layer motar, not only Improve the workability of mortar, and there is preferable water-retaining property, heat insulating ability and crack resistance, and the thickness of mortar can be less than 5mm, thus improve efficiency of construction.

For reaching above-mentioned purpose, the technical solution used in the present invention is: a kind of aerated blocks thin layer motar, with weight Percentages, including following component: portland cement 30～45%, graded sand and stone 40～55%, glass bead 3～15%, nothing Machine bentonite 0.5%, wood fibre 0.1%, water reducer 0.05%, cellulose ether 0.02%, starch ether 0.01%.

Preferably, the one during described graded sand and stone is natural siliceous sand, dolomite sand, natural river sand, mechanism quartz sand Or several mixture, fineness is 30～120 mesh.

Preferably, described glass bead is the expanded and vitrified small ball of 30～70 mesh.

Preferably, described inorganic bentonite is sodium bentonite, lithium bentonite or calcium-base bentonite.

Preferably, described cellulose ether is that methyl cellulose ether, hydroxypropyl methyl cellulose ether or hydroxyethyl methyl are fine One in dimension element ether, viscosity 20000～200000mpa s.

Preferably, described water reducer is how series high-efficiency water-reducing agent.

Due to the utilization of technique scheme, the present invention compared with prior art has the advantage that

Aerated blocks thin layer motar of the present invention not only improves the workability of mortar, and has preferably Water-retaining property, heat insulating ability and crack resistance, and the thickness of mortar can be less than 5mm, thus improve efficiency of construction, it is to avoid coat of plaster Hollowing, crack phenomenon.

Detailed description of the invention

Below in conjunction with specific embodiment, the present invention is described in further detail.

Embodiment 1, aerated blocks thin layer motar of the present invention, comprise by weight percentage, including as follows Component: portland cement 35%, graded sand and stone 50%, glass bead 14%, inorganic bentonite 0.5%, wood fibre 0.1%, Water reducer 0.05%, cellulose ether 0.02%, starch ether 0.01%.

Embodiment 2, aerated blocks thin layer motar of the present invention, comprise by weight percentage, including as follows Component: portland cement 40%, graded sand and stone 47%, glass bead 12%, inorganic bentonite 0.5%, wood fibre 0.1%, Water reducer 0.05%, cellulose ether 0.02%, starch ether 0.01%.

Embodiment 3, aerated blocks thin layer motar of the present invention, comprise by weight percentage, including as follows Component: portland cement 45%, graded sand and stone 45%, glass bead 9%, inorganic bentonite 0.5%, wood fibre 0.1%, subtract Water preparation 0.05%, cellulose ether 0.02%, starch ether 0.01%.

Above each component is added the mortar i.e. obtaining the present invention after suitable quantity of water uniformly mixes, after testing, embodiment 1-3 gained Mortar not only improve the workability of mortar, and there is preferable water-retaining property, heat insulating ability and crack resistance, and mortar Thickness can be less than 5mm, thus improve efficiency of construction, it is to avoid the hollowing of coat of plaster, crack phenomenon.

Below it is only the concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.All employings The technical scheme that equivalents or equivalence are replaced and formed, within the scope of all falling within rights protection of the present invention.
