The invention relates to an activated grinding aid for steel slag micropowder and a preparation method thereof, wherein the activated grinding aid comprises the following raw material components in parts by weight: 15 to 45 parts by weight of an amide compound, 3 to 35 parts by weight of an alkanolamine, 5 to 20 parts by weight of ethylenediamine or a derivative thereof, 0.1 to 0.5 part by weight of a defoaming agent, and 15 to 70 parts by weight of water. And sequentially adding 15-45 parts by weight of amide compound, 3-35 parts by weight of alkanolamine and 5-20 parts by weight of ethylenediamine or derivatives thereof into 15-70 parts by weight of water, mixing and stirring, and then adding 0.1-0.5 part by weight of defoaming agent to obtain the activating grinding aid for the steel slag micropowder. The activated grinding aid for the steel slag micropowder provided by the invention is simple in preparation process and low in dosage, has an excellent grinding aid effect, and can improve the activity index of the steel slag micropowder, especially the activity index of 28 d; and the steel slag micro powder does not contain chloride ions, so that the steel slag micro powder meets the national standard.
Description
Technical field
The invention belongs to the additive that uses in the useless admittedly application technology as the second resource field of industry, be specifically related to activated grinding aids of a kind of slag micro powder and preparation method thereof.
Background technology
Slag is the byproduct of Steel industry, and its quantity discharged accounts for 15%～20% of crude steel output, and wherein the slag more than 70% is the chemical constitution bessemer furnace slag similar to portland cement clinker, has potential gelling, and the application potential in cement concrete is bigger.China's slag burden has surpassed 100,000,000 tons at present, but reasons such as its chemical constitution fluctuation is big, hydrating capacity difference, effective rate of utilization is lower than 10%.The micronization of slag and efficient application in the cement concrete industry become present domestic slag and realize high added value, change one of the important channel of comprehensive utilization on a large scale.
In recent years, the slag activate micro powder that slag is prepared behind fine-grinding progressively has been applied in the cement concrete production.In concrete, slag micro powder is place of cement by a certain percentage, can significantly improve concrete performance on the one hand, as concrete workability and age strength far away, improves concrete permeability resistance and volume stability simultaneously, thereby is conducive to concrete weather resistance; On the other hand, can significantly reduce concrete folk prescription production cost, obtain good economic benefit.It is Dicalcium Phosphate (Feed Grade) (C that the essential mineral of bessemer furnace slag is formed
2S), tricalcium silicate (C
3S), RO reaches small-amount free calcium oxide (f-CaO), iron calcium aluminate (C mutually
4AF).Correlative study shows: its hydration heat total amount only for 10.5% of cement, can think that it is the very low Portland clinker of a kind of activity; In addition, the grindability of slag is relatively poor, and the energy consumption that independent grinding consumes is higher.Therefore, the activity that how effectively to improve the mill efficiency of slag micro powder and improve slag micro powder is the hot issue that promotes slag micro powder sizable application in the coagulating cement scholar at present.Adopt chemi-excitation can improve the slag activity to a certain extent, but cost performance is not high; And by the levigate physical excitation method that waits of slag is limited to the raising of slag activity, and the fine grinding degree that too improves slag can directly cause ton grinding pow consumption to rise, and application number is that 200810122227.8 Chinese patent literature has been reported a kind of be used to mixing concrete steel-smelting waste steel slag micro powder production technique.In actual industrial production, often by in grinding process, adding grinding aid to address this problem.
Application number is that 03121115.1 Chinese patent literature has been reported a kind of slag micro powder hardening accelerator as the concrete fine mineral admixture, its proportioning is: industrial aluminum sulphate slag 20～30%, active silica 30～50%(that natural nonmetalliferous ore is made is granularity＜1 micron wherein, account for 40～50%), cement clinker 20～30%, polyol surfactant 0.03～0.06%; Be spiked in the slag micro powder with powder body material, its consumption is 3%～6%.
Application number is that 201110326892.0 Chinese patent literature has been reported a kind of clad steel slag-grinding aid, is 15～30% tensio-active agents, 20～40% grinding aids, and 20～40% adjust agent, 5～15% carriers.Carrier is a kind of in silica flour, quartzy silica flour, the flyash, and tensio-active agent is trolamine and glycerol, and grinding aid is wooden calcium, and the adjustment agent is at least a in phosphoric acid salt, polyphosphoric acid salt or the sodium laurylsulfonate.
Application number is that the Chinese patent literature of 2011110202490.X has been reported a kind of slag grinding aid and preparation method thereof, comprise: 15～16 parts in tap water, 16.4～15.4 parts in urea, 0.4～0.6 part in sodium hydroxide, 2～4 parts of ethylene glycol, 28～20% parts of 20% poly carboxylic acid, 20～22 parts of trolamines, 20～22 parts of glycerine.Described raw material is mixed, stirs.The consumption of described slag grinding aid is 0.2% of slag quality.
Li Weifeng etc. (" concrete ", 2012,4:34-35) reported different grinding aid components to grinding and the Effect on Performance of bessemer furnace slag, modified polyalcohol, amide compound, glycerol, trolamine all have certain grinding aid ability to slag; The 1d of each slag micro powder sample, 7d and 28d determination of activity result such as table 4.By table as can be seen, mix the more blank sample increase by 8.64% and 5.93% of 7d, 28d activity index of 0.05% amide compound; The more blank sample of 7d, 28d activity index that mixes 0.02% glycerine increases by 5.7% and 1.78%; As the trolamine of the conventional grinding aid in the cement grinding and hardening accelerator the activity of slag micro powder is promoted poor effect, its 7d activity index only more blank sample increase by 2.55%, 28d activity index on the contrary more blank sample reduced by 0.59%.
Prior art and research mostly adopt traditional cement grinding aid component such as trolamine, glycerine etc. as grinding aid component and the activator of slag micro powder, DeGrain in the practical application, and 28 days activity indexs of slag micro powder do not improve and improve.
Summary of the invention
Technical problem to be solved by this invention is the activated grinding aids that a kind of slag micro powder is provided in order to improve the deficiencies in the prior art, the present invention also provides the preparation method of above-mentioned activated grinding aids, the activated grinding aids of this slag micro powder is in grinding aid, can effectively improve the activity index of slag micro powder, especially 28d activity index, make the improved performance of slag micro powder, production cost further reduces.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:
A kind of activated grinding aids of slag micro powder is characterized in that its feed composition and the shared weight part of each component are respectively: amide compound 15～45 weight parts, alkanolamine 3～35 weight parts, quadrol or derivatives thereof 5～20 weight parts, defoamer 0.1～0.5 weight part, water 15～70 weight parts.Preferred its feed composition and the shared weight part of each component are respectively: amide compound 19～40 weight parts, alkanolamine 5～30 weight parts, quadrol or derivatives thereof 8～15 weight parts, defoamer 0.1～0.3 weight part, water 20～65 weight parts.
