Abstract
The invention relates to a dry-mixed mortar material and a preparation method thereof. The preparation method comprises the following steps of: proportioning fly ash, coal slag, manganese slag, cement clinker, gypsum, limestone and lime according to the weight percentage shown in the specification of the invention; and then, feeding in a ball mill to grind into solid powder substances, wherein the weight of screen residue of the obtained product on a 0.080mm square hole screen is smaller than 8 percent and the mortar strength ranges from M2.5 to M20. The invention has the advantages that the dry-mixed mortar material can be used for substituting cement and lime, the product is suitable for building mortar in industrial or civil buildings, can be also used as mortar in engineering, such asplastering inner walls or outer walls, decorating walls or floors, and the like. The mortar has good stability, high early strength increase, short setting time and high hardening speed, and the invention improves the mortar flexibility and has convenient construction, simple operation, light labor intensity and little environmental pollution without influence or side effect on human bodies.
Description
Technical field
The present invention relates to a kind of making method of dry-mixed mortar material, be meant place of cement, lime especially, be applicable to the masonry mortar in industry or the covil construction, also can be used as interior external wall plastering, the mortar of engineerings such as wall, ground decoration.
Background technology
In existing technology, masonry mortar that buildings is used and motar, all adopting lime (lime putty) and the general cement of 32.5 grades is agglutinate, adds medium sand again and water stirs into mortar.Other has invention " a kind of mixed mortar cementitious material and method for making thereof " (patent No. is 96115079.3) to propose: during the preparation mixed mortar; Lime putty needs in liming tank, to add water cure more than seven days with unslaked lime; Become lime putty, pull out then, just can be used for preparing mixed mortar.It is very inconvenient that this agglutination material is prepared mixed mortar at the construction field (site).
" method for making of mixed mortar cementitious material is to get above-mentioned cement clinker, flyash and gypsum to put into ball mill; grind to form particle diameter less than 70 microns pressed powder, be mixed mortar cementitious material, during grinding; the weight content that makes cement clinker is 15%-45%; the weight content of flyash is 52.75%～84.25%, the weight content of gypsum is 0.75%～2.25% " simultaneously, " mixed mortar cementitious material " that above-mentioned method for making obtains---real example for " masonry cement "; Product performance are unstable, and the scope of application is narrower.
Summary of the invention
The objective of the invention is to: provide that a kind of to select multiple industrial residue for use be the making method of the dry-mixed mortar material of main raw material.It is according to waste residue physicals and color and water cut, utilizes all characteristics of building mixed mortar and construction cement mortar, solved mortar workability, hollowing, drawback such as ftracture, come off.The even more important meaning of the present invention is; Dry other raw material moisture content of heat energy when utilizing lime as the alkaline stimulator of mortar and thickening material and lime slaking; Strictness has been controlled various materials and has been gone into the preceding quality index of mill; The quality product of gained is more stable, and the scope of application is more extensive, also is more conducive to environmental protection.
The present invention is achieved in that dry-mixed mortar material is made up of flyash, cinder, manganese mud, cement clinker, gypsum, Wingdale and lime; Wherein flyash is to collect the powder that obtains in the coal fired thermal power plant coal-powder boiler flue gas, and loss on ignition is not more than 8%, and water cut is not more than 1%, and sulphur trioxide is not more than 3%, and other technologies require to meet the GB1596 GB; Cinder belongs to calcareous addition of volcano, and all natural or artificial are with silicon oxide, and aluminum oxide is the mineral material of staple; The levigate water that adds own mixes and stirs also non-sclerous; But after air hardening lime mixed, blunge then not only can harden in air again; And can in water, continue sclerosis person, be called calcareous addition of volcano; Cinder is the residue behind the boiler coal burning, and loss on ignition must not surpass 10%, and sulfur trioxide content must not surpass 3%, and other technologies require to meet the GB/T2847-1996 standard; Cement clinker is a kind of by mainly containing silicon-dioxide; Quicklime; Aluminium sesquioxide, the raw material of red oxide of iron are worn into fine powder by suitable proportioning and are burnt to partial melting, and the Calucium Silicate powder that is able to is the hydraulicity gum material of essential mineral composition; Cement clinker strength is greater than 52.5MPa, and other technologies require to meet the JC/T853 standard; Gypsum is a plaster of paris mineral products, and sulfur trioxide content should be greater than 30%, and other technologies require to meet the GB/T4131 standard; Wingdale is to be main with lime carbonate, and its content should be greater than 85%, and aluminium sesquioxide content should be less than 2%; Lime is the product that obtains after through roasting with calcium carbonate mineral, and calcium oxide content is greater than 85%; Manganese mud is to smelt the waste residue that the manganese alloy steel fire grate goes out.Dry-mixed mortar material is an attrition process powdering solid materials; Product fineness 0.080mm square hole sieve screen over-size is less than 8%, and component material weight proportion precentagewise is counted: flyash accounts for component material content 30%-60%, cement clinker and accounts for component material content 7%-35%, cinder and account for component material content 5%-7%, gypsum and account for component material content 5%-7%, Wingdale and account for that component material content 3%-8%, lime account for component material content 5%-11%, manganese mud accounts for component material content 5%-15%; During making; Prepare burden flyash, cinder, manganese mud, cement clinker, gypsum, Wingdale and lime by foregoing weight percent; Feed grinding in ball grinder then and become solid powder substance; Products obtained therefrom fineness 0.080mm square hole sieve screen over-size is less than 8%, and mortar intensity is M2.5 to M20.
The invention has the advantages that: 1, can place of cement, lime.Product is applicable to the masonry mortar in industry or the covil construction, also can be used as interior external wall plastering, the mortar of engineerings such as wall, ground decoration.2, mortar good stability, early strength increases fast, and time of coagulation is short, and setting rate is fast, has improved the snappiness of mortar, and easy construction is simple to operate, and light labor intensity is low in the pollution of the environment, has no impact and side effect on the human body.3, meet national policy low-carbon (LC), environmental protection, energy-conservation, recycling economy development product.Practice thrift 32.5 class g cements such as grade more than 30%, practice thrift lime (lime putty) more than 50%.4, dry-mixed mortar material has been opened up new industrial residue utilization, and all radionuclide is limited the quantity of and met the requirements in the waste residue through pyrotic smelting or incendiary chilling waste residue, and silicon-dioxide and aluminium sesquioxide content all can use more than 65 percent.
