Abstract
The invention discloses dry-mixed masonry mortar for industrial dust, belonging to a premixed dry-mixed masonry mortar material for a building. The dry-mixed masonry mortar is prepared from the following ingredients in parts by weight: 8-12 parts of cement, 10-20 parts of industrial dust, 0-3 parts of coal ash, 65-82 parts of aggregate, 0.3-0.5 part of compound activator, 0.08-0.1 part of compound water-retaining agent, 0.1-0.2 part of crack-resisting agent and 0-0.3 part of water repellent agent. Compared with the prior art, the dry-mixed masonry mortar can be additionally added with 10-20 percent fine powder with granularity of less than 200mu without causing cracking, therefore, the traditional provision that the addition amount of the fine powder with the granularity of less than 200mu is not more than 4 percent is thoroughly broken, and a bran-new path for utilization of industrial dust is developed.
Description
Technical field
The present invention relates to a kind of premixing dry-mixed mortar material for building, specifically a kind of industrial dust dry-mixed mortar.
Background technology
Along with the development of society, people improve constantly the requirement of construction quality, environmental requirement and civilized construction, do the favor that the advantage of mixing mortar obtains more and more people.
All form and be narrower than the superfine dust of 200 purposes in a large number every year such as mining, sandstone pulverizing, piece material grinding, plant produced, particularly forms the mine tailing fine powder about 400 orders in the exploitation of gold deposit process especially in a large number, occupies cultivated land the severe contamination air in a large number.
In the prior art, the used aggregate of mortar is narrower than 200 purpose fine powders can not be greater than 4%, otherwise mortar can very fast cracking in drying process.So,, also can't be applied at the dry-mixed mortar production field although contain a large amount of benefit materials in the industrial dust.
Summary of the invention
Technical assignment of the present invention is at above-mentioned the deficiencies in the prior art, and a kind of energy-conserving and environment-protective are provided, the industrial dust dry-mixed mortar that the cost of material is low.
Technical assignment of the present invention is realized in the following manner: the industrial dust dry-mixed mortar, make by the batch mixes of following weight proportion:
When being used for plastering on inner walls, above-mentioned industrial dust dry-mixed mortar need not use hydrophobizing agent.
Described cement is common 425# cement.
Described industrial dust is that mining, sandstone are pulverized, the formed superfine dust of 200 purposes that is narrower than of piece material grinding.
Described flyash is the above flyash of I and II.
Described aggregate is the mixture of one or more materials in the pulverized particles of machine-processed sand, river sand or building waste, and its fineness is less than 4 millimeters.
Described compound activator by trolamine, tri-isopropanolamine, polycarboxylate dehydragent is composite forms the weight ratio of trolamine, tri-isopropanolamine, polycarboxylate dehydragent 1: 1: 1.Described water-holding agent is that Vltra tears, polyacrylamide are composite by weight 3: 5.
Described anti-fissuring agent is that fineness is 30～60 purpose perlite or microcrystalline waxes.
Described hydrophobizing agent is polymkeric substance redispersible powder, sodium stearate or Zinic stearas.
The present invention is narrower than 200 purpose fine powders and can not surpasses 4% difficulty by adding exciting agent, water-holding agent and anti-fissuring agent etc., having overcome in the mortar aggregate.Gel material contents such as cement in the present technique dry-mixed mortar seldom, when the fine powder in the mortar surpasses relevant regulations, a large amount of fine powders and a spot of gelling material thorough mixing, coat mutually, make gelling material can not draw close mutually, connect, thereby lost pectisation, thereby caused phenomenons such as strength degradation, dry shrinkage and cracking.After adding exciting agent, excite the calcium ion in the fine powder to participate in hydration reaction, improve intensity, thereby resisted dry shrinkage and cracking, also reduced the volatilization of moisture, the hydration reaction that exists for of water provides primary condition; After adding water-holding agent,,, further resisted dry shrinkage and cracking for hydration reaction provides further assurance because moisture evaporation is slower; Distinctive anticracking agent in the present technique (uses perlite very common in the mortar, but all be used as aglite or lagging material, microcrystalline wax is usefulness seldom, and is main as insulation, waterproof) adding, utilize the telescopic action of anticracking agent, further reduced dry shrinkage and cracking.
Industrial dust dry-mixed mortar of the present invention compared with prior art has following outstanding beneficial effect:
(1) volume uses in dry-mixed mortar and is narrower than 200 purpose industrial dust greatly, overcome and be narrower than 200 purpose fine powder contents in the prior art mortar aggregate above 4% o'clock, mortar can Large Area Cracking deficiency, thoroughly overturned be narrower than 200 purpose fine powders in the aggregate can not be greater than 4% tradition regulation (being narrower than additionally admixture 10%-20% of 200 purpose fine powder addition contents), opened up a brand-new approach that industrial dust utilizes, and every technical indicator of product meets the every index request in the national sector standard fully, has energy-conservation, reduce discharging, characteristics such as cost is low;
(2) all raw materials are environment-friendly materials, really accomplish nontoxicly, adapt to people to environmental protection requirement;
(3) various raw materials are commercially available common product, are easy to realize.
