Description
Technical field
The present invention relates to a kind of gelling material, particularly relate to a kind of gelling material that contains calcium silicate slag and preparation method thereof.
Background technology
Calcium silicate slag is remaining residue from aluminous fly-ash extracts aluminum oxide.At present, it is domestic that what aluminous fly-ash had been realized to industrial applications is pre-desiliconizing-alkali-lime sinter process (patent publication No.: CN 102249253A) that Inner Mongolia Datang International Renewable Resources Development Co., Ltd. develops, first it utilize alkali to carry out pre-desiliconizing processing to flyash, obtains desiliconization liquid and flyash; Then in desiliconization liquid, add milk of lime reaction to generate after Calucium Silicate powder, obtain active calcium silicate through dealkalize, in flyash, add sodium carbonate, Wingdale etc., after roasting forms grog, more generate aluminum oxide through a series of subsequent disposal simultaneously.The method is being produced 1 ton of Al
2o
3time, being accompanied by and producing 2.2～2.5 tons of main components is beta-dicalcium silicate (β-Ca
2siO
4, be called for short β-C
2s) calcium silicate slag.
In the calcium silicate slag that pre-desiliconizing-alkali-lime sinter process forms, conventionally remain 2～4.5% water soluble alkali (Na
2o), it has very strong contaminative, particularly extremely serious to the pollution of soil and groundwater, and must carry out antiseepage processing to stockyard in the time storing up in a large number, thereby how effectively to process a large amount of calcium silicate slags and become aluminous fly-ash and put forward aluminium industry and need badly the problem of solution.
Calcium silicate slag and cement clinker composition approach, and therefore it can be used as cement additive use.But because alkali content in calcium silicate slag is too high, directly use can cause the generation of alkali-aggregate reaction, thereby cause concrete cracking and later strength to reduce.At present, there is the calcium silicate slag after a small amount of research and utilization dealkalize to prepare cement clinker, for example publication number is in the Chinese invention patent application of CN 101591150A, to disclose a kind of method of utilizing calcium silicate slag and carbide slag to produce silicate cement, it utilizes carbide slag to carry out de-alkali reaction to calcium silicate slag, and raw material are carried out obtaining cement clinker after high-temperature calcination, again itself and desulfurated plaster are carried out to grinding, make silicate cement.The method technique relative complex and cost are high, and particularly high-temperature calcination meeting reduces the activity of calcium silicate slag, and it is not fully used.
Publication number is that the Chinese invention patent of CN 103145357 A discloses a kind of calcium silicate slag complex cement and blended material thereof, this blended material is grinding after calcium silicate slag, zeolite powder and flyash are mixed, be cooled to lower than after 20 DEG C, then mix and make with calcium lignin sulphonate; This calcium silicate slag complex cement comprises cement and accounts for the blended material of complex cement total amount 30～40%.In use, the zeolite powder generation hydration reaction in complex cement, absorbs, solidifies the alkalimetal ion of calcium silicate slag inside.But this complex cement only adds calcium silicate slag on a small quantity, it is not to the β-C in calcium silicate slag
2s and alkali rationally utilize.
Summary of the invention
The invention provides a kind of gelling material that contains calcium silicate slag and preparation method thereof, for solving prior art silicon-calcium slag cement complicated process of preparation, cost is high, calcium silicate slag addition is few, not to the β-C in calcium silicate slag
2s and alkali carry out the technological deficiencies such as rationally utilization.
The invention provides a kind of gelling material that contains calcium silicate slag, comprise following component according to weight percentage: calcium silicate slag 30～65%, flyash 5～40%, cement clinker 10～30%, granulated blast-furnace slag 5～30%, gypsum 3～10%, additive 0.5～3%.

Flyash of the present invention is the main solid waste that coal-burning power plant discharges, and for example it can be the flyash that the international Togtoh of Datang generating limited-liability company forms; The residue that when described granulated blast-furnace slag (being designated hereinafter simply as slag) is the blast-furnace smelting pig iron, the melts that is main component with silicate and silico-aluminate of gained is formed after quenching granulating; Described cement clinker, gypsum are the conventional raw material of this area.
Gelling material provided by the present invention is taking calcium silicate slag as main raw material, be equipped with in right amount flyash, slag and cement clinker, and add on a small quantity gypsum and additive, this gelling material has good early strength and later strength, may be due to except forming traditional Ca-Si based cementitious material, thereby the alkali in calcium silicate slag can also form Si-Al based cementitious material by activated slag, that is to say, what the present invention formed is a kind of composite gelled material that simultaneously comprises Ca-Si base and Si-Al base, wherein Si-Al based cementitious material has good early strength, and β-C in Ca-Si based cementitious material
2s has certain aquation gelling, and its aquation gelation rate is relatively slow, therefore can bring into play good intensity in the later stage, in addition,, because the alkali in calcium silicate slag is fully utilized in activated slag, therefore can not cause the generation of alkali-aggregate reaction.This gelling material is by making full use of the β-C in calcium silicate slag
2two kinds of components of S and alkali, not only without calcium silicate slag is carried out to dealkalize processing, and can add calcium silicate slag in a large number, have therefore greatly reduced production cost.
Further, moisture content≤2% of described calcium silicate slag.In the time that in raw material calcium silicate slag, moisture content is higher, can its moisture content be down to below 2% by drying and processing, the calcium silicate slag of moisture content below 2% be prevented from caking in the time storing, and is conducive to practical application.
Gypsum of the present invention can be for desulfurated plaster (being the industry by-product gypsum that coal-fired or oily industrial enterprise obtains after the sulfurous gas of administering in flue gas), dihydrate gypsum, dehydrated gyp-, contain CaSO
4trade waste etc.Additive of the present invention can comprise an alkali metal salt (such as sodium salt, sylvite etc.) and/or other conventional additives (such as retardant, hardening accelerator etc.), and an alkali metal salt can form Si-Al based cementitious material by auxiliary spark excitation slag; Particularly, described additive can be selected from potassium sulfate, sodium carbonate, salt of wormwood, sodium-chlor, Repone K, sodium aluminate, sodium sulfate, sodium polyphosphate, borate, sulfonated lignin and phosphatic one or more.
Further, the granularity of described gelling material is 300～500m
2/ kg, this size range can make the each component in gelling material fully contact, and then brings into play preferably the interaction between each component.
The present invention also provides a kind of preparation method of above-mentioned gelling material, comprises the steps:
Described calcium silicate slag, flyash, cement clinker, granulated blast-furnace slag, gypsum and additive are mixed and make compound;
Described compound is carried out to grinding, make gelling material.
Preparation method of the present invention, the not strict restriction of the sequencing that each raw material is added, and can mix according to this area ordinary method.Particularly, carrying out before described mixing, can first be dried described calcium silicate slag, make to store for future use after its moisture content≤2%.
Further, described grinding is that to make the granularity of the gelling material making be 300～500m
2/ kg, it can adopt cement tube mill to carry out, and the size of tuber grinder can be Φ 3.2 × 13m.
Enforcement of the present invention, at least has following advantage:
