Abstract
The invention relates to a non-cement anti-crack mortar to overcome the disadvantages of the prior art. The invention on the one hand does not use cement completely, saves cement dosage and reduces energy consumption, and on the other hand can increase the utilization amount of fly ash. The non-cement anti-crack mortar is composed of a non-cement mortar masterbatch and an additive. The non-cement mortar masterbatch consists of the following components by mass percentage: 10-40% of ultra-fine fly ash, 50-87% of sand, 2-10% of lime and 0-3% of gypsum. The ultra-fine fly ash has a particle size of 5-10 micrometers, and the additive includes 2.00-4.00% of redispersible latex powder, 0.20-0.50% of a water-retaining agent, 0.10-0.50% of cellulosic fiber, and 0.20-1.00% of anti-crack fiber. The non-cement anti-crack mortar prepared by the invention has the advantages of simple operation, excellent performance and low cost, also can save cement dosage, makes heavy use of fly ash, and responds to the national call for energy conservation and emission reduction.
Description
Technical field
A kind of non-cement anticracking grout of the present invention, belongs to building material technical field.
Background technology
In recent years, reduce discharging the promotion energetically of policy at national energy-saving under, Energy Saving Technique for Buildings in Our Country is developed rapidly, and External Walls Heating Insulation occupies dominant position, and positive contribution has been made in the development for Building Energy-saving Work.At present, in external wall thermal insulation method, method the most common is sticking heat-preservation plate, and in external thermal insulation system, warming plate surface all needs to smear one deck anticracking grout, to reach the result of use of heat-insulation system weather resistance.Employ a large amount of cement in traditional anticracking grout, higher cement mixing content not only affects the weather resistance that anticracking grout uses, and there is huge energy consumption.
Summary of the invention
The present invention overcomes the deficiencies in the prior art, provides a kind of non-cement anticracking grout, does not use cement completely on the one hand, has saved the consumption of cement, reduced the consumption of the energy, can increase the utilization of flyash on the other hand.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of non-cement anticracking grout, is made up of cement-free mortar masterbatch and additive;
Described cement-free mortar masterbatch is made up of by mass percentage following component: superfined flyash 10-40%, sand 50-87%, lime 2-10% and gypsum 0-3%; The particle diameter of described superfined flyash is 5-10 μm;
Described additive comprises redispersable latex powder 2.00-4.00%, water-holding agent 0.20-0.50%, cellulosic fibre 0.10-0.50%, anti-crack fiber 0.20-1.00%; In additive the consumption of each component with the quality of cement-free mortar masterbatch for benchmark measures.
The particle diameter of above-mentioned superfined flyash is 5-10 μm, and its activity index of 28 days should be not less than 110%.
The preferred 7-9% of consumption of lime.
Above-mentioned sand can be any one in natural sand and Machine-made Sand, and should meet the regulation of national standard " construction sand " (GB/T14684-2011), the silt content of natural sand should be less than 5.0%, and clod content should be less than 2.0%, and the particle diameter of sand is less than 1mm.
The trade mark of additive is all that those skilled in the art can carry out selecting according to real economy ability and needs, different brands or the redispersable latex powder of the trade mark or ether of cellulose are due to the difference of performance, consumption may increase and decrease to some extent, generally can not exceed limited range of the present invention.
The flyash that have selected ultrafine of the invention substitutes cement completely as main raw material and prepares mortar, has broken the technology barriers that prior art adopts conventional pulverized coal ash replacing partial cement.And the dry blend preparation technology of superfined flyash mortar is very simple, only needs simple proportioning to mix.Use simple, curing condition is low, does not need the curing condition of high temperature or high pressure completely.No matter be the reutilization technology from waste resource, also or the aspect such as recruitment cost, resources conservation, technology of the present invention all tool has very great significance.
Compared with prior art the present invention has following beneficial effect.
1, cement is not used completely, functional, the technical requirements of relevant criterion can be met.
2, preparation technology is simple, and mixed by a certain percentage by desired raw material, the stirring that adds water can use.
3, flyash can be utilized in a large number, solve a large amount of flyash for a long time and pile up the problem of land occupation.
4, effectively can reduce the consumption of the energy, reduce CO
2quantity discharged, be conducive to environmental protection.
