Abstract
The invention discloses a tailing fine powder modifier which is characterized by comprising the following components in mass ratio: 20-40% of surface modifier, 10-22% of particle extraction agent, 5-15 parts of polar additive and 23-65% of polar solvent. When the tailing fine powder modifier is used for the tailing fine powder production process, the specific surface area of the tailing fine powder can be improved by 5-20% and the 7-day activity index of the tailing fine powder can be improved to 70-85%. When the tailing fine powder doped with the modifier provided by the invention is used for cement or concrete production, the blending amount can be improved and the clinker using amount can be reduced under the same fracture resisting and compression resisting conditions, so that the problem of low tailing fine powder utilization rate is solved and the cement and concrete production cost is saved.
Description
Technical field
The present invention relates to comprehensive utilization of tailing field, be specifically related to utilize mine tailing to act on the mine tailing fine powder of cement or concrete production, particularly a kind of mine tailing fine powder properties-correcting agent.
Background technology
Mine tailing is as a kind of bulk solid waste, and accumulating amount is huge, and utilizes it to prepare mine tailing fine powder to can be used as a kind of effective means and solve a large amount of mine tailing and pile up problem.But owing to forming the element such as main component silicon, aluminium, iron, calcium, magnesium of mine tailing, mainly exist with more SA ore deposit phase form in mine tailing, and effectively can not improve its activity by means of only the mine tailing fine powder of grinding, therefore mine tailing fine powder is can only add on a small quantity for when cement or concrete production, utilising efficiency is lower, and the unresolved fundamental issue that it is piled up.
Chinese invention patent CN 102249582 B " a kind of active bauxite dressing tailing micro-powder and preparation method thereof ", disclose a kind of activated alumina and select mine tailing fine powder and preparation method, this activate micro powder is mixed by the flyash of the mineral processing tailing of bauxite of 70 ~ 98wt% and 2 ~ 30wt%, make through grinding after calcining at 700 ~ 900 DEG C, as the raw materials of alkali-excited cement or the high activated admixture of composite Portland cement, the method is improved the activity of mineral processing tailing of bauxite fine powder, energy consumption is large, is unfavorable for environmental protection.
Chinese invention patent CN 102744211 B " method of the modification of a kind of phosphorus mine tailing and sorting enriched phosphorus and magnesium ", disclose a kind of phosphorus mine tailing through the modified method therefrom reclaiming the valuable component such as magnesium, phosphorus, wherein mentioning the modification of phosphorus mine tailing is by adding admixture, dodecylbenzene, sodium soap, trolamine, triethyl hexyl phosphoric acid and making, but the object of phosphorus mine tailing modification is for reclaiming magnesium, phosphorus in phosphorus mine tailing, but not for cement or concrete production.
Chinese invention patent CN 103601399 A " a kind of cement modifier of improvement ", disclose a kind of properties-correcting agent for improving cement performance, main component is flyash, butadiene-styrene copolymer, trolamine, magnesium hydroxide, pentaerythritol fatty ester, calcium lignin sulphonate and tetradecyl aldehyde, this properties-correcting agent main purpose strengthens its activity further on the existing greater activity basis of cement, has essential distinction with the present invention.
Summary of the invention
The object of the invention is to, a kind of properties-correcting agent being exclusively used in mine tailing fine powder is provided, mine tailing fine powder can be made to have higher activity index.When admixture, the mine tailing fine powder of properties-correcting agent of the present invention is when for cement or concrete production, under equal bending and compressive strength, its blended amount can be improved, reduce grog usage quantity, solve the problem that mine tailing fine powder utilization ratio is low, save cement and concrete production cost simultaneously.
Mine tailing fine powder properties-correcting agent of the present invention comprises following component, and surface-modifying agent, particle put forward agent alive, Polar adjuvants, the large class of polar solvent four.
Described surface-modifying agent comprises one or more in Phenylsulfonic acid, methylsulphonic acid, Witco 1298 Soft Acid, methacrylic acid, butene dioic acid, sodium lignosulfonate, calcium lignin sulphonate, magnesium lignosulfonate, calcium cyclamate, methylpropene sodium sulfonate.
