Technical field

The present invention be a kind of with flyash, slag, phosphorus slag, coal gangue, slag, zeolite, the calcining metakaolin is independent or compound be main raw material, admixture silicon ash, concrete chemical admixture, exciting agent carry out modification, add entry, levigate in water, become the concrete mineral admixture and the manufacture method thereof of pulpous state.The present invention relates to the concrete material field of building material industry.

Background technology

Product related to the present invention and technology have following:

(1) concrete dry powder flyash fusion material is the dust that the fuel-burning power plant flue is discharged, and receives and sorting through dust-precipitator, obtains the dry powder subparticle.National standard is stipulated the quality index that is used for cement and concrete flyash, and it is divided into Three Estate, and the flyash that is lower than three grades can not use.National standard is to being used for cement and concrete flyash institute water content, loss on ignition, sulphur content, regulation all having been made in the influence of cement and concrete flowability and intensity.The flyash that concrete flyash fusion material only limits to the dry method discharging just can be used as concrete admixture, and the flyash of wet method discharging can't utilize.The effect of flyash fusion material in concrete mainly is the workability of improving fresh concrete, and the first level flour coal ash can reduce concrete water requirement, for improving concrete later strength better effects arranged, and flyash also has to add at inside concrete uses usefulness as.But because the flyash early activity is lower, competence exertion after flyash fusion material will arrive 28 days to the contribution of concrete strength reduces concrete early strength.

(2) concrete slag powders adulterant is that the waste residue that ironmaking is discharged directly enters chilling in the water, obtains the above particle of vitreum content 90% (weight), and the oven dry back is levigate, becomes the slag powders adulterant, and specific surface area is at 350m ²More than/the kg.The slag powders adulterant is the highest concrete dry powdery adulterant of activity that obtains by grinding up to now, mill thin more, and activity is high more.The slag powders adulterant just began performance to the contribution of concrete strength at 7 days.But, the very difficult mill of slag, the production energy consumption of slag powders adulterant is very high, makes its production cost very high.The specific surface area of general business-like product is at 400m ²About/kg, specific surface area improves again, and the grinding energy consumption will increase by a larger margin, and manufacturer and with bearing per family is uneconomical on economic benefit.The minority occasion dry grinds slag to specific surface area 800m ²About/kg, be used for special concrete, concrete strength property contribution is improved greatly, but the grinding pow consumption of such dry powder ultrafine slag powder be very high, make its production cost far above cement, in general concrete, can't accept during actual the use.

(7) concrete levigate metakaolin adulterant, be with natural kaolin mineral through 600 ℃～900 ℃ calcinings, slough crystal water, become the metakaolin structure, the dry powder adulterant that obtains through grinding.

(8) concrete flyash, slag powders composite blend are the dry powder powders that is mixed and made into mutually by flyash and slag powders.

(9) concrete steel-making slag powder, slag powders composite blend are the dry powder powders that is mixed and made into mutually by steel-making slag powder and slag powders.

(10) concrete steel-making slag powder, slag powders, flyash composite blending material are the dry powder powders that is mixed and made into mutually by steel-making slag powder, slag powders and flyash.

(11) in actual engineering, when preparation high strength or high performance concrete, the normal and slag powders of silicon ash, the compound use of flyash.

These adulterant majorities have all obtained using in concrete, and wherein the technology of flyash fusion material, slag powders adulterant, zeolite powder adulterant, silicon ash adulterant is very ripe, has all formulated national standard in a lot of countries.Steelslag powder as additive, colliery powder adulterant and composite blend have also become commodity production, sale and use, and have formulated the product standard of enterprise-level or local level.

Outside the silica removal mortar, all these available coagulation soil adulterants all are the powdered products, and their manufacture method all is to carry out under drying regime, mainly adopts oven dry, grinding, selective separation process, product all is the exsiccant pressed powder, require water content according to weight ratio below 1%.Owing under drying regime, solid is carried out grinding, need very high energy, the power loss that equipment causes is also very big, therefore production cost was just very high when the particle of the powdery concrete admixture made of dry process was meticulous, can't satisfy concrete cost requirement, perhaps the fineness ratio of adulterant product is thicker, and active performance is slow.Unique moisture pulpous state adulterant is exactly the silicon mortar, and it is that nature becomes superfine particle, and transportation just adds entry for convenience becomes jelly, is not to pass through levigate and product that obtain.

Up to now, find the concrete admixture of the pulpous state that the process grinding obtains.
