Abstract
The invention discloses an adhesive mortar for an ALC (autoclaved lightweight concrete) wallboard. The adhesive mortar comprises the components in parts by weight: 300-400 parts of common silicate cement, 50-150 parts of coal ash, 500-600 parts of quartz sand, 5-15 parts of redispersible latex powder, 0.5-1.5 parts of lignocellulose and 0-1.0 part of polystyrene amide. After the adhesive mortar disclosed by the invention is applied, the ALC wallboards are firmly adhered and are good in integrity, and the adhesive mortar is convenient and efficient to construct, the labor intensity is reduced, the operational environment is improved, and the cost is low and can be controlled.
Description
Technical field
The present invention relates to building material technical field, particularly a kind of bonding mortar for ALC wallboard.
Background technology
ALC is the abbreviation of Autoclaved lightweight concrete (AutoclavedLightweightConcrete), is the one of high-performance steam-pressing aero-concrete.ALC plate is main raw material with flyash (or silica sand), cement, lime etc., through many aerocretes sheet forming (including treated reinforcing steel bar) of autoclave curing, is the one of building light-weight batten.ALC plate has following features: plate is lightweight, and design load is little, because its quality is loose porous, is good insulation and sound-proof material; Because sheet material is thin when making wallboard, expand building usable floor area.Plate is easy for installation, and speed of application is fast.Therefore, ALC plate both can do wallboard, can do roof boarding again, was a kind of building material of superior performance.
But ALC plate is in the process of construction, when boning with adhesive mortar, because ALC plate and mortar are the materials of two kinds of character, again because ALC plate quality is loose porous, mortar-chalked joint and mend easily produce crack, also can affect its function and attractive in appearance.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the invention provides a kind of bonding mortar for ALC wallboard, solve the problem that existing ALC plate mortar-chalked joint and mend easily produce crack.
Technical scheme of the present invention is such realization:
A kind of bonding mortar for ALC wallboard, it is made up of the component of following weight parts: general purpose portland cement 300 ~ 400 weight part, flyash 50 ~ 150 weight part, quartz sand 500 ~ 600 weight part, redispersable latex powder 5 ~ 15 weight part, lignocellulose 0.5 ~ 1.5 weight part, poly-third ethernamine 0 ~ 1.0%.
Wherein, preferably, a kind of bonding mortar for ALC wallboard, it is made up of the component of following weight parts: general purpose portland cement 300 ~ 400 weight part, flyash 50 ~ 150 weight part, quartz sand 500 ~ 600 weight part, redispersable latex powder 5 ~ 15 weight part, lignocellulose 0.5 ~ 1.5 weight part.
Wherein, preferably, a kind of bonding mortar for ALC wallboard, it is made up of the component of following weight parts: general purpose portland cement 300 ~ 400 weight part, flyash 50 ~ 150 weight part, quartz sand 500 ~ 600 weight part, redispersable latex powder 5 ~ 15 weight part, lignocellulose 0.5 ~ 1.5 weight part, poly-third ethernamine 0.5 ~ 1.0%.
Wherein, preferably, described quartz sand is the dry quartz sands of 70 ~ 140 objects.
Wherein, preferably, described flyash is second class powered coal ash.
Bonding mortar preparation method of the present invention is as follows: accurately take each raw material, stir and form.For the dry powder compound of single-component.Blunge is needed during use, per ton with reference to amount of water 300kg.
Beneficial effect of the present invention:
1. the silicate cement that the present invention is used as gelling material, fast solidifying, early strength and later strength high, frost resistance, anti-carbonation properties, wear resistance is better than other cement.
2. the SiO of solubility in raw material powder coal ash of the present invention
2, Al
2o
3isoreactivity composition when there being water to exist, can with Ca (OH)
2water generation reaction Calucium Silicate powder (C-S-H) and drated calcium aluminate (C-A-H), consume Ca
2+, reduce Ca
2+separate out surface probability.In addition, fly ash form effect improves workability, the homogeneity of mortar, enhances mobility, water-retentivity simultaneously, and mixing-water requirement is reduced, and reduces the rear mortar porosity of sclerosis.And flyash of the present invention and silicate cement react the intensity that can increase cement.
3. the redispersable latex powder that the present invention is used is spray-dired polymer dry powder, it can significantly improve inorganic mineral material adhesiveproperties, improve snappiness, hydrophobic nature, the weathering resistance of polymer mortar, clear up body of wall self stress-strain, thus greatly improve and ensured polymer mortar opposing and cleared up the circulation of self drying shrinkage stress-strain and the external world hot rain and freeze-thaw cycle causes the ability of warm and humid stress-strain, avoid the cracking of mortar synthem and come off.
4. the lignocellulose that the present invention is used is that natural timber processes through chemical treatment, mechanical process the organic wadding fibrous material obtained, nontoxic, tasteless, pollution-free, "dead", there is good effect to preventing coating cracking, raising water-retentivity, the stability improving production and the workability of construction, the sticking power etc. of effects on surface of gaining in strength, strengthen.
5. poly-third ethernamine that the present invention is used has high molecular, neutral charge and efficient characteristic of condensing, therefore it can be made to keep certain water content when being added in bonding mortar, significantly reduce the velocity of evaporation of moisture, thus play Water-saving effect, make mixture have good workability.
6. act synergistically between each composition of the present invention, form stereoscopic protective system, fundamentally solve the problem that mortar-chalked joint and mend easily produce crack.
7., after using bonding mortar of the present invention, firm pasting between ALC wallboard block and block, good integrity, and convenient and quick construction, reduce labour intensity, improve operating environment, with low cost controlled.
