Abstract
The invention belongs to the field of building materials and in particular relates to adhesive mortar for a lautoclaved lightweight concrete panel. The adhesive mortar is prepared from cement, pulverized fuel ash, an adjusting admixture, quartz sand, a thickening agent and rubber powder, wherein the sum of the weight percentages of the cement, the pulverized fuel ash, the adjusting admixture and the quartz sand is 100%, namely 10-20% of the cement, 8-18% of the pulverized fuel ash, 2.5-4.5% of the adjusting admixture and the quartz sand as balance; the thickening agent accounts for 0.03-0.05% of the sum of the weight percentages of the cement, the pulverized fuel ash, the adjusting admixture and the quartz sand, and the rubber powder accounts for 0.5-0.7% of the sum of the weight percentages of the cement, the pulverized fuel ash, the adjusting admixture and the quartz sand. The dry-blended adhesive mortar has relatively high water retention property, high caking property, and relatively low shrinking percentage, is matched with the lautoclaved lightweight concrete panel to effectively improve the cracking resistance of a wall body, can ensure the stability of the wall structure and can effectively prevent the wall from cracking and avoid other quality problems.
Description
technical field
The invention belongs to building material field, be specifically related to a kind of autoclaved lightweight concrete board (ALC plate) adhesive mortar, this adhesive mortar has the feature such as high water conservation, high bonding, lower shrinkage.
Background technology
Autoclaved lightweight concrete board is a kind of novel wall material, there is the advantages such as lightweight, sound insulation, insulation, both can do the materials for wall such as interior wall and exterior wall of building body, roof boarding and floor plates can be done again, be a kind of New Building Materials of superior performance, be used widely in the last few years.But while autoclaved lightweight concrete board is widelyd popularize, also there are more quality problems in the body of wall of building by laying bricks or stones with autoclaved lightweight concrete board, as: all there is the problems such as metope cracking, hollowing, seepage in a lot of construction wall, cause sound insulation of wall, heat-insulating capability to decline, also have a strong impact on overall appearance and structural stability.The major cause of this result is caused to be the water retention of traditional cement mortar used between autoclaved lightweight concrete board and cohesive strength is lower and shrinking percentage is larger.
Compared with special adhesive mortar, common sand-cement slurry water retention is poor, and autoclaved lightweight concrete board has vesicular structure due to it, is easy to be siphoned away by water from adhesive mortar, cause screed water ratio to decline, cement cannot carry out effective aquation and cause cohesive strength to decline; Simultaneously the shrinking percentage of ordinary mortar is also higher and cohesive strength is relatively low, in use, cohesive force between mortar and sheet material is not enough to resist the contraction of mortar self and sheet material and causes body of wall to occur crack, and causes the appearance of a series of disadvantage of masonry panel.
For preventing autoclaved lightweight concrete board from use occurring the quality problems such as cracking, be necessary the special adhesive mortar of research and development autoclaved lightweight concrete board.
Summary of the invention
The object of the invention is to provide a kind of autoclaved lightweight concrete board (ALC plate) adhesive mortar, and this adhesive mortar has the feature such as high water conservation, high bonding, lower shrinkage, 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 autoclaved lightweight concrete board adhesive mortar, this adhesive mortar is made up of cement, flyash, adjustable solidification agent, quartz sand, thickening material and rubber powder; Wherein, cement, flyash, adjustable solidification agent and quartz sand in weight percent sum for 100%: cement 10-20%, flyash 8-18%, adjustable solidification agent 2.5-4.5%, surplus is quartz sand; Thickening material is the 0.03-0.05% of aforementioned four kinds of raw material weight sums, and rubber powder is the 0.5-0.7% 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.
Described rubber powder is preferably vinyl acetate and ethylene copolymer redispersable latex powder.
The invention discloses a kind of autoclaved lightweight concrete board adhesive mortar to fill a prescription, this dry-mixed mortar has higher water conservation, adhesive property, also there is lower shrinking percentage simultaneously, with autoclaved lightweight concrete board with the use of the resistance to cleavage that effectively can improve body of wall, ensure the stability of wall body structure, effectively avoid body of wall to occur the quality problems such as cracking.In addition, adhesive mortar of the present invention also has energy-conserving and environment-protective, easy construction, the advantage such as with low cost.
Compared with prior art, the beneficial effect of adhesive mortar of the present invention:
The special adhesive mortar of ALC plate that the present invention develops mainly for the handling characteristics of autoclaved lightweight concrete board, it has good water retention property and higher cohesive strength, and its lower shrinking percentage also ensure that masonry structure is avoided occurring the quality problems such as cracking simultaneously.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 autoclaved lightweight concrete board adhesive mortar, this adhesive mortar is made up of cement, flyash, adjustable solidification agent, quartz sand, thickening material and rubber powder; 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 rubber powder is vinyl acetate and ethylene copolymer redispersable latex powder.
Described in each embodiment, the preparation method of autoclaved lightweight concrete board adhesive 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 adhesive mortar and water weight ratio 6:1, water mixing is stirred 3-5min and can be used.
The autoclaved lightweight concrete board adhesive mortar formula of embodiment 1 to 3 and the performance test results as shown in table 1.
