The high performance building binding material consists of cementing powder of fly ash, meta kaolin and latex powder; alkaline solution of water glass, sodium hydroxide and water; and sand in certain weight proportion. It is prepared through mixing the raw materials inside a stirrer. It has low water absorption, high binding performance and high durability.
Description
Technical field
The invention belongs to building material technical field, be specifically related to a kind of high-performance building binding material and preparation method thereof.
Background technology
Polymer-modified cement mortar is because its high cohesive strength and high resistance to cleavage have obtained application more and more widely.Cement is a kind of Industrial products of high pollution.Along with the enhancing of environmental consciousness, people are devoted to seek the substitute of cement, and are devoted to improve patching material and old concrete agglutinating endurance quality.
Geopolymer is a kind of environmental type gelling material.Geopolymer is to excite the sal raw material with alkali, at normal temperatures a class novel inorganic gelling material that obtains by chemical reaction.The raw material sources of ground polymeric material are wide, with low cost.Wherein the sal raw material can adopt each silicon, aluminium matter mineral and industrial solid castoff, as flyash, (partially) kaolin, slag, zeolite, quartz sand, building castoff etc.; Alkali-activator mainly adopts NaOH and water glass.Therefore, geopolymer had both had the premium properties of organic polymer, pottery, cement, had the starting material wide material sources again, and technology is simple, less energy consumption, advantage such as environmental pollution is little, and is with low cost.
The present invention makes full use of geopolymer material starting material characteristics widely, utilize the compound matrix material that has high-adhesion energy and high adhesive durability simultaneously of preparing of trade waste flyash and metakaolin, thereby when reaching high bond strength, have the energy-saving and environmental protection effect concurrently, and then reduced cost relatively, improved the competitiveness of product in market.
Summary of the invention
The object of the present invention is to provide a kind of high-performance building binding material and preparation method thereof with energy-saving and environmental protection effect.
A kind of high-performance building binding material that the present invention proposes is made up of glued powder, basic solution and sand, and wherein, the mass ratio of glued powder and basic solution is 1.5: 1～2: 1, and the mass ratio of sand and glued powder is 6: 4～7: 3; Described glued powder is made up of flyash, metakaolin and latex powder, and the mass ratio of metakaolin and flyash is 2～6: 8～4, and the mass ratio of latex powder and glued powder is 0～1: 10; Described basic solution is formulated by water glass, sodium hydroxide and water, and its weight ratio is: water glass: sodium hydroxide: water=2～6: 1.4～1: 6.6～3.
Among the present invention, the modulus of described water glass is 3.3.
Among the present invention, described latex powder apparent density is 540g/L, and ash content is 11%, and its minimum film-forming temperature is 4 ℃.
The preparation method of the high-performance building binding material that the present invention proposes: its concrete steps are: water glass, sodium hydroxide and water are mixed with basic solution by weight ratio, and cool to room temperature; Glued powder and sand are put into stirrer, mix, then basic solution is joined in the stirrer, stir, promptly get required building binding material.
The present invention compares with existing similar techniques, has following major advantage:
1. the diversity selected of starting material.The used glued powder flyash of product of the present invention is trade waste, and metakaolin is a kind of less energy-consumption material, and its utilization ratio in geopolymer is reached more than 80%.And present matrix material mainly is the cement of high pollution, so product of the present invention can reduce production energy consumption, economizes on resources, and has more the market competitiveness.
2. mass-producing.Preparation method of the present invention is simple, does not need special technology, is suitable for large-scale industrial production, is easy to generate scale and benefit.
3. high adhesive durability.Compare with traditional matrix material, product of the present invention is except higher self Adhesive Tensile Performance of Young, and it and concrete adhesive property and weather resistance all obviously improve; And the bond effect uniqueness, under alternation of wetting and drying and freeze-thaw cycle interaction rugged environment, can play more permanent cohesive action.
4. low-cost.Product preparation process of the present invention is simple, and utilizes refuse in a large number, and is with low cost.
So technological method provided by the invention has more practical value than traditional similar techniques method.
In the matrix material provided by the invention, various starting material had both had not same-action, interacted again, and preparation technology's design also all differs from one another.At first, 2 kinds of functions of product of the present invention realize by 2 kinds of approach: adhesive property relies on the efficient cementation and the artificial formed interface structure closely of compaction moulding technology of water glass; Secondly, the airtight hole that adhesive durability can rely on latex powder to mix back formation greatly reduces the suction of water, and the elastic performance that itself has makes its freeze-thaw-circulation ability obtain large increase in addition.
Description of drawings
Fig. 1 is that the embodiment of the invention 3 gained building binding materials and 28 days cohesive strength of concrete slab compare.
Embodiment
Further specify the present invention below by embodiment.
Embodiment 1-embodiment 9:
According to the formulated matrix material of table 1, concrete preparation method is respectively: water glass, sodium hydroxide and water are mixed with basic solution, and cool to room temperature; Glued powder metakaolin, flyash, latex powder and sand are put into stirrer simultaneously, it is mixed, then basic solution is joined in the stirrer equably, make the geopolymer mortar.The adhesive tensile resistance intensity of test gained building binding material and concrete slab.Ultimate compression strength 〉=the 30MPa of precast slab is of a size of 250mm * 250mm * 50mm.Concrete floor is inhaled with suction cleaner before and gone surface dirt, the building binding material that will mix and stir is smeared out the coherent mass of a 50mm * 50mm * 5mm size at concrete floor then, after the sample forming, under 20 ± 3 ℃ of temperature, relative humidity is maintenance to 14 day in 50 ± 5% the curing room, each proportioning is tested 4 groups of data.
The prescription of table 1 building binding material (mass ratio)
With the long duration test that bonds of gained matrix material:
To be divided into two groups of A, B according to 10 bonding testing pieces of the moulding of embodiment 3 gained.A organizes maintenance under 20 ± 3 ℃ of temperature, 50 ± 5% relative humidity conditions.Maintenance is put into 20 ± 2 ℃ water to the B group test specimen in regulation length of time soak and took out in 18 hours, be placed in-20 ± 3 ℃ the refrigerator constant temperature 3 hours.Take out the high-temperature cabinet constant temperature 3 hours put into 50 ± 3 ℃ again.24 hours is a circulation, carries out 10 circulations altogether.Taking out test specimen left standstill in the laboratory two hours.After 10 circulations, the cohesive strength of test A group and B group.
As can be seen from Fig. 1, building binding material that the present invention obtains and 28 days cohesive strength of concrete slab have reached 3.13MPa, and through after 10 alternation of wetting and drying one freeze-thaw cycle, the trial-production material is only compared than sample with the cohesive strength of concrete floor and reduced 15%.
