Abstract
The invention relates to a modified superfine mineral slag micropowder with cement setting retarding effect, which is prepared from the following raw materials in parts by weight: 950-960 parts of mineral slag, 38-45 parts of electrolytic manganese slag, 0.2-0.4 part of triethanolamine, 0.1-0.3 part of triisopropanolamine, 0.2-0.3 part of polyether glycol, 0.2-0.4 part of 1,4-cyclohexanedimethanol, 0.5-0.8 part of nano polytetrafluoroethylene, 60-70 parts of desulfurized gypsum, 0.1-0.3 part of sodium hypophosphite and 0.3-0.5 part of sulfurized olefin cotton oil. By using the triethanolamine, triisopropanolamine and the like as the raw materials, the residual charge on the micropowder surface can be shielded, the Si-O bond rupture in the mineral slag can be promoted, and the micropowder agglomeration can be prevented, thereby saving the energy consumption. The nano polytetrafluoroethylene is utilized to lower the surface energy, prevent the particles from aggregation and enhance the dispersity of the micropowder. By using the electrolytic manganese slag, the modified superfine mineral slag micropowder has the cement setting retarding effect, and reduces the gypsum consumption.
Description
Technical field
The present invention relates to slag micropowder preparation field, particularly relate to a kind of modified superfine slag micropowder with cement retardative effect and preparation method thereof.
Background technology
At present, China's iron and steel output is at about 3.5 hundred million tons, and produce 1 ton of pig iron with domestic mean level (ML) and produce 0.50 ton of slag calculating, China's slag output is at about 1.75 hundred million tons.Therefore, how utilizing slag solid waste, is the problem that Chinese metallargist studies for many years always, is also to develop a circular economy, build a conservation-minded society and a realistic problem that friendly environment society should solve emphatically.Slag great majority use as cement mixture for a long time, with cement clinker intergrinding, the fineness of slag weighs general below 250m2/kg by specific surface area, this does not make its potential hydraulically active be not fully exerted, from the energy and resource view, can say that it is huge waste to a kind of precious resources that slag is used as the adulterant of conventional cement.(generally at more than 400m2/kg) after slag separate grinding to certain fineness, then be incorporated in cement and concrete, the workability of fresh concrete and the weather resistance of maturing can be improved significantly.But in order to obtain the breeze of larger fineness, often need the time that grinding is longer, and this can increase energy consumption.Meanwhile along with the prolongation of grinding time, material specific surface area increases gradually, and its specific surface area can also increase, and thus, subparticle is assembled mutually, the trend of conglomeration strengthens.Through after a period of time, the homeostasis process of " grinding reunion " can be in mill, reach so-called " the grinding limit ".In this state, even if extend grinding time again, material also difficult grinding obtains thinner, sometimes even makes particle thicker.This phenomenon is not obvious when common grinding, but often occurs in the middle of fine-grinding and superfine pulverizing.Adopt vertical grinder, control in 400 ~ 440m2/kg scope according to the specific surface area of national standard general S95 level slag micropowder.Horizontal ball mill slag micropowder specific surface area generally can only control at 350 ~ 370m2/kg.These slag micropowders, because three days activity indexs are generally lower than 65%, the weakness that early strength is obviously on the low side, its lateral reactivity is not in full use, and use properties is also subject to significant limitation.The specific surface area of fine powder can be improved at present by adding grinding aid, thus reach the object of energy efficient, reduction mechanical wear.Utilize ethylene glycol, trolamine and some inorganic salt as grinding aid, improve mill efficiency, reach energy efficient, reduce the object of mechanical wear, but or can not meet the needs of production, but also need the composition improving slag micropowder, improve the performance of cement.
Summary of the invention
The object of the present invention is to provide a kind of modified superfine slag micropowder with cement retardative effect, the good dispersity of this slag micropowder, has cement retardative effect, decreases the consumption of gypsum.
