Abstract
The invention discloses masonry mortar special for aerated building blocks. The masonry mortar is prepared from, by mass, 25% of cement, 5% of coal ash, 44.3-54.3% of yellow sand, 15.0-25.0% of tailings and 0.7% of admixture, wherein the admixture is composed of a modifying agent and a thickening agent, and the modifying agent is one or a mixture of cellulose ether, an entraining agent and a water reducing agent. According to the masonry mortar, a large amount of coal ash is effectively utilized, so that the problem of environment pollution is solved, and the manufacturing cost is reduced; in addition, environment-friendly pollution-free composition proportions are achieved, the using amount of natural yellow sand is reduced, and meanwhile the bonding performance of the masonry mortar special for the aerated building blocks is improved through one or the mixture of the cellulose ether, the entraining agent and the water reducing agent.
Description
Technical field
The present invention relates to a kind of masonry mortar, refers to a kind of aerated-block special masonry mortar particularly.
Background technology
Aerated-block is for main raw material with siliceous material and calcareous material (lime, cement), admixture foaming agent (aluminium powder), through the stirring that adds water, hole is formed, the porous silicate goods made by technological processs such as casting, precuring cutting, steam press maintenances by chemical reaction.Aerated-block is widely used due to many good characteristics such as its high-strength light, impervious waterproof, fire protection flame retardings.The mortar used in aerating stripping and slicing building process at present requires that good cohesiveness and resistance to air loss are to adapt to the vesicular structure of aerating stripping and slicing.
Flyash, be receive to catch the thin ash got off from the flue gas after coal combustion, flyash is the primary solids refuse that coal-burning power plant discharges.The main oxides of power plants flyash consists of: SiO2, Al2O3, FeO, Fe2O3, CaO, TiO2 etc.Flyash is one of industrial residue that the current discharge capacity of China is larger, and along with the development of power industry, the flyash quantity discharged of coal-burning power plant increases year by year.A large amount of flyash does not add process, will produce airborne dust, atmosphere pollution; River can be caused to silt up if enter water system, and toxic chemical substance wherein also can work the mischief to human body and biology, how effectively processing these objectionable impuritiess is objects that those skilled in the art urgently study.
Summary of the invention
The invention provides one and not only make full use of flyash solution problem of environmental pollution, and form a large amount of intensive stable, micro-bubble, increase the aerated-block special masonry mortar of adhesive property.
A kind of aerated-block special masonry mortar, composed of the following components by mass percentage:
Described admixture is properties-correcting agent and viscosifying agent, and described properties-correcting agent is one or more mixtures of ether of cellulose, air entrapment agent, water reducer.This kind of aerated-block special masonry mortar effectively make use of a large amount of flyash and solves problem of environmental pollution, reduce manufacturing cost, and achieving the composition proportion of green non-pollution, the usage quantity decreasing natural yellow sand increases aerated-block special masonry mortar adhesive property by one or more mixtures of ether of cellulose, air entrapment agent, water reducer simultaneously.Described CHARACTERISTICS OF TAILINGS SAND is iron tailings sand.
Described admixture is ether of cellulose, air entrapment agent, water reducer, viscosifying agent, wherein each composition by weight percent 3: 2: 9: 80.
Described viscosifying agent is the mixture of sepiolite powder, montmorillonite powder, wilkinite powder, wherein each composition by weight percent 3: 2: 4.Sepiolite powder be a kind of tool layer chain-like structure containing Shuifu County's magnesium silicate clay mineral.Rhombic system or oblique system are general in bulk, earthy or fibrous agrregate.Sepiolite is a kind of fibrous hydrous magnesium silicate, usually in white, light gray, the color such as pale yellow, opaque also lackluster.The shape that they have as soil block, the strange cot shape of some one-tenth one or nodular.Can see that they are got together by countless filament to line up sheet under an electron microscope.Montmorillonite is the layer mineral be made up of the hydrous alumino silicates that particle is superfine, and it is important clay mineral that montmorillonite subtribe belongs to one of smectite race mineral, is generally bulk or earthy.Molecular formula (Al, Mg) 2 [Si4O10] (OH) 2nH2O, centre is alumina octahedral, the clay mineral of the three-layer tablet shape structure formed for silicon-oxy tetrahedron up and down, moisture and some exchange cations at crystal structure interlayer, there is higher loading capacity, there is higher water-swelling ability.Wilkinite powder has the thickening property that good water-swelling property and dispersion and suspension and pulping performance greatly improve viscosifying agent.Sepiolite powder, montmorillonite powder, wilkinite powder be combined with each other when utilizing sepiolite to run into water and can absorb a lot of water thus become softness, and once dry just hardening, under soft condition, adsorb large quantity of moisture under montmorillonite powder, the effect of wilkinite powder, form denseness and the viscosity that good thickening property improves aerated-block special masonry mortar.
Described air entrapment agent is Chinese honey locust powder, Rhizophora stylosa stilit root powder, autumn eggplant stilit root powder, dodecyl dimethylamine oxide mix formation according to weight percent 15: 2: 2: 1.Chinese honey locust is also referred to as Chinese honey locust, and the extract containing a kind of pungent in Chinese honey locust, main component is triterpenoid saponin.It has and good causes performance, and triterpenoid saponin is elementary composition by monosaccharide groups, glycosides base and glycosides.Aglycon have two joining aglycons compositions, and next aglycon of generalized case can connect the monose of more than 3 or 3, forms a larger pentacyclic triterpene space structure.Monose in monosaccharide groups has a lot of hydroxyl can form hydrogen bond with water molecules, thus has stronger wetting ability, and the aglycon in aglycon base has lipophilicity is hydrophobic group.Triterpenoid saponin belongs to nonionic surface active agent.After triterpenoid saponin is water-soluble, macromole is attracted on liquid-gas interface, forms the aligning of two kinds of groups, thus reduces the tension force at bubble interface, make the generation at new interface become easy, if mechanically stirred solution, will produce bubble.And due to triterpene soap molecular structure comparatively large, the molecular film of formation is thicker, and elasticity and the intensity of walls are higher, and bubble can keep relative stability.By the sea, it has flourishing ventilating tissue and fine and close molecular structure can help Chinese honey locust powder to form fine and close bubble for Rhizophora stylosa stilit root primary growth.Autumn this kind of plant of eggplant stilit root is Fujian frequent species in mangrove forest, is also the kind that can resist cold, can be distributed to neighbouring province Zhejiang northwards, except except Fujian in Hainan, Guangxi, Guangdong, Taiwan, Hong Kong bay have distribution.In the region on interior beach, having distribution from outbeach, on the more smooth mud bank in mouth of the river bay, it has flourishing ventilating tissue and fine and close molecular structure can help Chinese honey locust powder to form fine and close bubble in many growths.The bubble of these densifications fully coordinates aerating stripping and slicing to build the powerful viscous force of space on interface, the stiff rear formation of pore by laying bricks or stones, and impervious water resistance is not that common masonry mortar can be compared.
Aerated-block special masonry mortar of the present invention effectively make use of a large amount of flyash and solves problem of environmental pollution, reduce manufacturing cost, and achieving the composition proportion of green non-pollution, the usage quantity decreasing natural yellow sand increases aerated-block special masonry mortar adhesive property by one or more mixtures of ether of cellulose, air entrapment agent, water reducer simultaneously.
