Description
Technical field
The invention belongs to the technology of producing cement field, be specifically related to a kind of black composite Portland cement and production method thereof.
Background technology
Cement is a kind of powdery hydraulicity inorganic coagulation material, is divided into general cement and cement special according to purposes and performance.General cement mainly refers to: six large class cement, i.e. silicate cement, ordinary Portland cement, Portland blastfurnaceslag cement, Portland pozzolana cement, Portland fly ash cement and composite Portland cements of GB175-2007 regulation; Cement special refers to the cement of special purpose, mainly comprises:
(1) white portland cement (abbreviation white cement): take Calucium Silicate powder as main component, the poor grog of irony adds an amount of gypsum, the levigate white hydraulic cementing materials of making.
The starting material of silicate cement generally are divided into calcareous raw material, clayey raw material and correction material (ferric oxide or silicon oxide).The calcareous raw material of white cement is generally pure Wingdale, chalk, clayey raw material adopts the lower sandy clay of iron content (purer quartz sand), pure kaolin usually, the silicon rate of white cement clinker and aluminium rate are all very high, and therefore, white cement is higher than silicate cement to the requirement of raw material.Because irony requires lowlyer in the white cement raw material, be called and avoid iron cement, lectotype selection will be less with or without ironware equipment; Because the requirement of white cement whiteness, the control of raw material calcining temperature, demanded fuel also are higher than silicate cement.
(2) colored portland cement: with white portland cement clinker and high quality white colored stone cream, mix pigment, common levigate the forming of admixture.
Composite Portland cement (be called for short complex cement, PC cement claims again mixed cement) is by the levigate hydraulic cementing materials of making of mixing material, the proper amount of gypsum of Portland clinker, two or more regulation.Mixing material has the nonactive mixing materials such as granulated blast-furnace slag, volcanic ash, flyash, iron-tion slag, Refining Chromium Iron slag isoreactivity mixing material and Wingdale, sandstone, titanium slag.Composite Portland cement density 2.8～3.0g/m
3, tap density 1000～1200kg/m
2Composite Portland cement can be made rational use of resources by utilizing solid waste as compound, alleviates again the environmental burden of the whole society, can also reduce production costs, and continues its production method of further investigation and kind and has great economy and social value.
The annual solid waste that produces several hundred million tons of China, special quantity is all very huge for being industry coal-boiler waste residue, Metal smelting waste residue and production of construction materials waste residue, both wastes natural resources, and environment is produced pollute again.At present, the cement that utilizes industrial residue to produce based on the rational Match of various waste residue micro mist adulterants, can improve concrete compactness, forms the concrete structure of low densification, high-density, low defective, greatly improves concrete work-ing life.The in recent years comprehensive utilization of resources of China's Cement industry obtains important breakthrough, and the waste of cement industry utilization utilizes in the total amount in national solid waste and surpasses 80%.Particularly composite Portland cement is by adopting few grog, many micro mists, low cost cement production technology, utilize various industrial residue waste materials as blended material, such as blast-furnace slag, flyash, volcanic ash, ettle (waste material of quartz sand, mine tailing, lead skim etc.), coal gangue, grind soil, burn shale etc., mix in the cement clinker, powder mix is worn into the composite Portland cement of corresponding kind, to greatest extent flyash, slag, coal gangue, smelted furnace cinder and other industrial residues of power consumption, metallurgy, coal-mining industry production.
The method of producing at present black cement is levigate and make with white portland cement clinker, high quality white colored stone cream and carbon black, but owing to having relatively high expectations of white cement raw material, fuel, and the production difficulty of grog is larger, need specialized factory to produce, complex process, yield poorly, cost is high, is unfavorable for applying of black cement.
If can develop a kind of take composite Portland cement as the basis, prepare black cementitious composite silicate cement by adjusting other industrial solid castoff of interpolation, because it is take the composite Portland cement grog as the basis, therefore its batching requires low and obtains easily, the cement unit weight for preparing is light, colour stable.If further can also provide the production method that this kind black composite Portland cement technique is simple, cost is low, and the recycle that can also solve industrial solid castoff, wide market outlook and social value will be had.
Summary of the invention
The first purpose of the present invention be to provide a kind of prepare burden require low and obtain easily, unit weight is light, the black silicon acid salt cement of colour stable; The second purpose is to provide that a kind of production technique is simple, output is high, environmental protection and energy saving, black method for producing Portland cement that production cost is low.
The technical scheme that solves the first purpose of the present invention is: a kind of black composite Portland cement, comprise that mass percent is 60～75% Portland clinker, 10～20% boiler slag, 3～5% antimony slag, 5～8% watt slag, 3～5% gypsum, each composition quality per-cent sum is not more than 100%.
The technical scheme that solves the second purpose of the present invention is: a kind of black composite Portland cement production method is to be that 60～75% Portland clinker, 10～20% boiler slag, 3～5% antimony slag, 5～8% watt slag, 3～5% gypsum make by levigate homogenizing with mass percent.
Black composite Portland cement of the present invention take Portland clinker as the basis, consists of mixing material by adding boiler slag, antimony slag, watt slag, adds levigate making behind the gypsum again.Coal firing boiler waste residue wherein has the chemical ingredients similar to active addition flyash, can play the effect that substitutes flyash in the common composite Portland cement; The color of regulating cement by adding nonactive mixing material antimony slag and watt slag plays again filling effect.Because it is less demanding to consist of the composition quality of black composite Portland cement, and major part be the industrial solid waste residue, therefore having batching and requiring low and easy acquisition; Because wherein mixing material mostly is greatly industrial residue, therefore also have the light characteristics of composition silicate unit weight, and because of the characteristics of food ingredient, further also light by 5～8% than common composite Portland cement unit weight; Because black is by forming after antimony slag, watt slag physics the is levigate rear adding homogenizing, the black cement that therefore forms has colour stable, the dark characteristics of black.Production method of the present invention, the technique of employing are the ripe production method of common composite Portland cement, compare with common black manufacture of cement that production technique is simple, output is high, and all manufacture of cement producers all can produce; Make because employing take Portland clinker as the basis, is added the industrial solid waste residue as mixing material and the part gypsum is levigate, so the raw materials for production environmental protection, the mixing material of interpolation does not need calcination process, has energy-conservation characteristics; In addition, utilize the industrial solid waste residue as mixing material, it is low also to have a raw materials for production cost, and production cost and composite Portland cement are suitable, favourable promoting the use of.
