Abstract
The invention belongs to the field of building materials, and particularly relates to masonry mortar for autoclaved aerated concrete. The masonry mortar is composed of cement, pulverized fuel ash, a thickening time control agent, silica sand and a thickening agent, wherein the sum of the weight percentage of the cement, the pulverized fuel ash, the thickening time control agent and the silica sand is 100% by including 8-12% of cement, 6-8% of pulverized fuel ash, 2-3% of the thickening time control agent and the balance of silica sand; the weight of the thickening agent is 0.015-0.035% of the sum of the weight of the four raw materials. The masonry mortar has good water retention performance, can prevent water in a mortar layer from being absorbed too quickly by autoclaved aerated concrete, guarantees the effective hydration of mortar, and facilitates solid bonding of the mortar layer with a base layer, so that the masonry mortar has good bonding performance, and effectively avoids the quality problems of wall cracking and the like.
Description
technical field
The invention belongs to building material field, be specifically related to a kind of steam-pressing aero-concrete special masonry mortar with high-moisture-retention.
Background technology
Steam-pressing aero-concrete is a kind of novel wall material, have the advantages such as lightweight, sound insulation, insulation, and it can utilize flyash in a large number, because of and there is environment-friendly function, be used widely in the last few years.But while steam-pressing aero-concrete is widelyd popularize, also there are more quality problems in the body of wall of building by laying bricks or stones with steam-pressing aero-concrete, there is the problems such as metope cracking, seepage in a lot of construction wall, have a strong impact on the insulation of body of wall, defening effect, also bring structural safety hidden danger to a certain degree simultaneously.The major cause of this result is caused to be that autoclave aerated concrete building block employs traditional cement mortar when building by laying bricks or stones.
The less use admixture of traditional cement mortar, main component is cement and sand, and water retention is poor, and shrinking percentage is also higher.And autoclave aerated concrete building block belongs to vesicular structure, there is very strong water-absorbent, be easy to from masonry mortar, water be siphoned away, masonry mortar layer water ratio is caused to decline, cement cannot carry out effective aquation, causes the cohesive force between itself and autoclave aerated concrete building block lower, under the acting in conjunction that screed self and autoclave aerated concrete building block shrink, very easily cause between screed and autoclave aerated concrete building block and ftracture, thus make masonry panel produce the quality problems such as crack.Therefore, be necessary to develop steam-pressing aero-concrete special masonry mortar, to prevent the generation of above-mentioned situation.
Summary of the invention
The object of the invention is to provide a kind of steam-pressing aero-concrete masonry mortar had compared with high-water performance, and it can effectively avoid body of wall to occur the quality problems such as cracking.
For achieving the above object, the present invention adopts following technical scheme:
A kind of steam-pressing aero-concrete masonry mortar, this masonry mortar is made up of cement, flyash, adjustable solidification agent, quartz sand and thickening material; Wherein, cement, flyash, adjustable solidification agent and quartz sand in weight percent sum for 100%: cement 8-12%, flyash 6-8%, adjustable solidification agent 2-3%, surplus is quartz sand; Thickening material is the 0.015-0.035% of aforementioned four kinds of raw material weight sums.
Concrete, described cement is preferably ordinary Portland cement.
Described adjustable solidification agent is preferably quick hardening sulphoaluminate cement.
Described thickening material is preferably cellulose ethers thickening material, as methyl cellulose ether, hydroxypropyl methyl cellulose ether, ethoxyl methyl cellulose ether, hydroxyethyl ether cellulose etc.
Masonry mortar of the present invention can effectively prevent moisture in mortar from being absorbed by autoclave aerated concrete building block, also there is the characteristics such as low heat conduction, lower shrinkage, high bonding, itself and autoclave aerated concrete building block are with the use of splitting resistance and the heat-insulating property that effectively can improve masonry structure entirety, there are energy-conserving and environment-protective, easy construction, the advantage such as with low cost.
Compared with prior art, the beneficial effect of masonry mortar of the present invention:
The present invention develops the steam-pressing aero-concrete special masonry mortar with good water retention property mainly for the strong absorptive of steam-pressing aero-concrete, to make screed moisture can not by the too fast absorption of steam-pressing aero-concrete, ensure that mortar can carry out effective aquation, thus be beneficial to and bond firmly with basic unit, make it have good cohesiveness, effectively avoid the quality problems such as wall crazing.Meanwhile, the present invention make use of the waste coal ash of power plant emission in a large number, not only has good economic benefit, also has good environmental benefit and social benefit.
Embodiment
Below in conjunction with embodiment, technical scheme of the present invention is described further, but protection scope of the present invention is not limited thereto.
embodiment 1-3
A kind of steam-pressing aero-concrete masonry mortar, this masonry mortar is made up of cement, flyash, adjustable solidification agent, quartz sand and thickening material; The weight of each raw material is in table 1; Wherein, described cement is ordinary Portland cement; Described adjustable solidification agent is quick hardening sulphoaluminate cement; Described thickening material is hydroxypropyl methyl cellulose ether.
Described in each embodiment, the preparation method of steam-pressing aero-concrete masonry mortar is specially: get above-mentioned each raw material in proportion, join in mortar mixer, mix, to obtain final product.During construction usage, according to masonry mortar and water weight ratio 6:1, water mixing is stirred 3-5min and can be used.
Embodiment 1 to 3 gained steam-pressing aero-concrete masonry mortar is carried out performance test with reference to " steam-pressing aero-concrete masonry mortar and plastering mortar " (JC 890-2001), and test result is in table 2.
The parts by weight of raw materials composition of masonry mortar described in table 1, embodiment 1-3
The performance test results of masonry mortar described in table 2, embodiment 1-3
As can be seen from Table 2: the properties detected result of masonry mortar of the present invention meets the relevant regulations of industry standard to steam-pressing aero-concrete masonry mortar, and the water retention property of its excellence ensure that the moisture in screed can not be absorbed in a large number by autoclave aerated concrete building block, thus ensure that the carrying out of hydrated cementitious in mortar, effectively prevent the quality problems such as screed hollowing, cracking.In addition, because the overall proportion of gelling material is less, employ flyash in a large number again simultaneously, make the present invention also have the advantages such as with low cost, economy, environmental protection.
