Abstract
The invention discloses dry-process desulphurized fly ash dry-mixed mortar, which belongs to the field of pre-agitated dry-mixed mortar materials for buildings. The mortar is formed by mixing the following materials in a ratio by weight: 8-12 parts of cement, 15-20 parts of dry-process desulphurized fly ash, 68-77 parts of aggregate, 0.25-0.4 part of composite excitant, 0.07-0.1 part of composite water retaining agent, 0.2-0.3 part of composite anti-cracking agent and 0-0.3 part of water repellent agent. Compared with the prior art, the dry-process desulphurized fly ash dry-mixed mortar adopts extremely fine ash formed by a dry-process desulfurizing technology as a main material and has the characteristics of energy saving, environment friendliness, low material cost and the like.
Description
Technical field
The present invention relates to a kind of premixing dry-mixed mortar material for building, specifically a kind of dry desulfurization ash dry-mixed mortar.
Background technology
The gas desulfurization technology of the present coal firing boiler of China mainly contains three kinds of forms: wet desulfurizing process, semi-dry desulfurizing process, dry desulfurizing process.Only Baosteel will produce 170,000 tons desulfurized ash every year, and in the prior art, the terra alba that wet desulfurizing process is produced has some more sophisticated approach that utilize, and desulfurized ash is not also had the sophisticated approach that utilizes basically.
On the other hand, 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.How desulfurized ash being applied to the dry-mixed mortar production field, is that those skilled in the art thirst for the technical barrier that solves always.
In order to address the above problem, publication number is to disclose a kind of " microdilatancy inorganic heat insulation mortar preparation method " in the patent documentation of CN102010166A.The hydraulicity of this techniques make use desulfurized ash and micro-expansibility have just utilized the hydraulicity material in the desulfurized ash, like chainotte matter mineral, free calcium oxide, success be applied to the dry-mixed mortar production field.But the consumption of desulfurized ash is very little in the mortar, and is very limited in the contribution of making aspect waste application, the environmental protection and energy saving.
Summary of the invention
Technical assignment of the present invention is the deficiency to above-mentioned prior art, and a kind of energy-conserving and environment-protective are provided, the dry desulfurization ash dry-mixed mortar that the cost of material is low.
Technical assignment of the present invention is realized by following mode: dry desulfurization ash dry-mixed mortar, process by the batch mixes of following weight proportion:
Said cement is common 425# cement.
Formed superfine dust when said dry desulfurization ash adopts dry desulfurizing process for coal-fired flue-gas, its staple is calcium sulfite, calcium sulfate, quicklime, flyash, lime carbonate.
Said 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.
Can utilize general exciting agent of the prior art; Like sodium sulfate, water glass, yellow soda ash, Sulfothiorine etc.; Excite calcium sulfite in the desulfurized ash, calcium sulfate, quicklime, flyash etc. that hydration reaction takes place as soon as possible, but preferably use following compound activator.Said compound activator by alum, Tai-Ace S 150 is composite forms the weight ratio of alum, Tai-Ace S 150 1: 1.
In order to slow down moisture evaporation, can use known water-holding agents such as hydroxyethylmethyl-cellulose, methylcellulose gum, SEPIGEL 305, but the following compound water retaining agent of preferred use.Said compound water retaining agent by Vltra tears, CMC 99.5 is composite forms, the weight ratio of Vltra tears, CMC 99.5 is 4: 3.
In order further to reduce dry shrinkage and cracking, can use general anti-fissuring agents such as quicklime, calcium sulfate, microcrystalline wax, polypropylene fibre, but compound anti-fissuring agent below preferred the use.Said compound anti-fissuring agent is by perlite and X 2073 is composite forms, and the weight ratio of perlite and X 2073 is 3: 1.
Said perlitic fineness is 30～60 orders.
Said hydrophobizing agent is polymkeric substance redispersible powder, StNa or Zinic stearas.
Staple in the dry desulfurization ash is calcium sulfite, calcium sulfate, quicklime, flyash, lime carbonate etc.; Wherein the content of former three is more than 70%; The all non-constant of volume stability, in use, because chemical reaction velocity is different; Cause condensing and the expansible asynchronism(-nization), thereby cause cracking; In the dry-mixed mortar of the present invention after adding compound activator; Excite calcium sulfite, calcium sulfate, quicklime, flyash etc. that hydration reaction takes place as soon as possible, improved intensity, thereby resisted dry shrinkage and cracking; Also reduced the volatilization of moisture, the hydration reaction that exists for of water provides pacing items; After adding water-holding agent,,, further resisted dry shrinkage and cracking for hydration reaction provides further assurance because moisture evaporation is slower; Distinctive compound anti-fissuring agent in the present technique (uses perlite very common, but all is used as aglite or lagging material in the mortar; X 2073 is also very common, but mainly as air entrapment agent to improve workability) adding, utilized the telescopic action of anti-fissuring agent, further reduced dry shrinkage and cracking.
Dry desulfurization ash dry-mixed mortar of the present invention compared with prior art has following outstanding beneficial effect:
(1) can the mass consumption dry desulfurization ash, opened up a ripe new way of utilizing of desulfurized ash;
(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.
