Description

The manufacture method of hardened slag product
Technical field
The present invention relates to slag (ス ラ グ; Slag) manufacture method of hardenite, specially refer to utilization at the powder shape hot metal pretreatment slag that is difficult to aspect the civil construction materials such as roadbed material, engineering materials, rostone, marine structure, other concrete substitute effectively utilize, improve the intensity of the hardenite after making, the technology of minimizing minute crack.
Background technology
The slag basicity height that in steel making working procedure, produces, and contain CaO in a large number with the state of a compound (below be designated as free CaO).For this reason, it absorbs moisture and expands easily, and not towards the purposes as the civil construction material resemble the blast-furnace slag, its disposal for a long time and making full use of as problem carries over.Therefore, in order to break this situation, several technological development that make full use of the steel-making slag have energetically also been attempted.The trial that particularly can see the material that contains silicon-dioxide that makes resemble the blast-furnace slag and the slag of making steel to make up and make full use of.
For example, Te Kaiping 10-152364 communique discloses a kind of hydration hardenite: promptly, contain the aggregate more than 50% and have the material that contains silicon-dioxide of latent hydraulicity and have a kind or 2 kinds of materials in the material that contains silicon-dioxide of pozzolanic reaction, and and utilize hydration reaction and hardened bonding material mixes and the hydration hardenite made with steel-making slag.Again, Te Kaiping 2-233539 communique discloses such slag bear: promptly, when making all bonding material, fine aggregate, coarse aggregate become the steel slag of pulverizing and fragmentation, use the steel slag that in above-mentioned bonding material, has mixed blast-furnace slag and steel-making slag and the slag bear of making.Further, open the spy that disclosed example is on the flat 1-126246 communique: be about to converter slag and carry out magnetic separation, drying after being ground into below the 5mm, so that reach 3000～5000cm 2/ g, use to pulverize the back with the mixed of 10～30 weight % in the blast-furnace slag fine powder converter slag and the example of the blast furnace cement made.In addition, we before once proposed in EP0994196A1: to make the particle diameter that contains more than the 50 weight % be the steel-making slag of the steel-making slag below the 5mm and contain SiO according to hydration reaction 2The one-tenth block method of the steel-making slag of the mixture solidified of the material of 〉=30 weight %.Further, open to disclose on the clear 59-169966 communique in the blast furnace water slag the spy and add, mixed roadbed material with 10～60% the converter slag powder that parches that weight ratio represents.
, the inventor uses above-mentioned prior art, and having manufactured experimently with the steel-making slag is the hardened slag product (following also only cry sometimes " hardenite ") of raw material, and the result has understood fully problem points as described below.
At first, according to the spy open flat 10-152364 communique, the spy opens the method for being put down in writing among flat 1-126246 communique and the EP0994196A1, as making steel slag when using converter slag, then during maintenance in 20 ℃ water (cure), sometimes hardenite damages, so can not meet the demands., investigated this reason in minute detail.
In recent years; in order to protect the inner lining refractory of converter; and in slag, add rhombspar and dead roasting magnesium oxide etc.; as because of; MgO concentration in the converter slag uprises. and distinguishes: when using the high converter slag of such MgO concentration; the MgO of the compound state that this converter slag is contained (below be designated as free MgO) expands because of maintenance hydration in the water, and the hardenite that make damages.
Based on this knowledge, the inventor expects using the hot metal pretreatment slag that contains free MgO hardly as the steel-making slag.So, open above-mentioned spy and to adopt this hot metal pretreatment slag in the aggregate of the steel-making slag of being put down in writing in the flat 10-152364 communique, under same condition, manufactured experimently hardenite., the not enough 20N/mm of the compressive strength of resulting hardenite 2, be not durable with this place of cement concrete.
At this, so-called " hot metal pretreatment " is meant in converter and before the refining molten iron, adds various refining agents in advance in the molten iron before converter is supplied with, carry out the processing of desiliconization, dephosphorization, desulfurization etc.In this application, the slag that will produce in this pre-treatment is called " hot metal pretreatment slag ", and it is contained in the category of steel-making slag.Below " taking off the Si slag ", " taking off the P slag " and performances such as " taking off the S slag " be meant the slag that when molten iron being taken off the Si pre-treatment respectively, take off the P pre-treatment and take off the S pre-treatment, produces.
On the other hand, opening in the method that flat 2-233539 communique put down in writing above-mentioned spy, is the hardened slag product of raw material in order to make with the converter slag, need with slag broken be fine powder., in converter slag, contain free MgO as described above more.Therefore, slag itself is hard to be difficult to become fine powder, so existence is pulverized the very big problem of cost in order to be ground into reactive high fine powder., with above-mentioned the same, use the hot metal pretreatment slag contain free MgO hardly, open raw material that flat 2-233539 communique put down in writing according to above-mentioned spy and cooperate and manufactured experimently hardened slag product.
Again, when replacing the special converter slag of opening in the flat 1-126246 communique to use the hot metal pretreatment slag, the not enough 20N/mm of the compressive strength of the hardenite of gained 2, replace cement concrete not to be durable.In addition, contain 3000cm 2During the above hot metal pretreatment slag of promptly about 0.07mm below the/g, the intensity of hardenite is also not enough or also produced many minute crack.
Further, the raw material of announcing in according to EP0994196A1 cooperates, and uses the hot metal pretreatment slag and when carrying out the manufacturing of hardened slag product, also can see most minute crack sometimes on hardenite as the steel-making slag.And distinguish: these hardenites are when particularly hardened slag product is used in the blocky construction being used to resemble desired strength and aesthetic appearance, in any case also not anti-use.
Further, will open the converter slag powder of being put down in writing in the clear 59-169966 communique the spy and be changed to the hot metal pretreatment slag, and manufacture experimently hardened slag product, slag only condenses as a result, in any case also can not get the hardenite resemble the concrete.
The objective of the invention is: in light of this situation, use also can not cause the manufacture method of hardened slag product of the generation of the undercapacity of hardenite of manufacturing and minute crack as part of raw materials even propose make steel slag.
Disclosure of an invention
The present invention in order to achieve the above object is to be the following hot metal pretreatment slag of 1.18mm with containing (a) particle diameter: 15～55 quality % and (b) particle diameter be the following blast-furnace slag of 0.1mm: the material of 5～40 quality % makes its hardened hardened slag product manufacture method mix stirring with water after.
Again, the present invention is to be the following hot metal pretreatment slag of 1.18mm with containing (a) particle diameter: 15～55 quality %, (b) particle diameter are the following blast-furnace slag of 0.1mm: 3～36 quality % and (c) cigarette ash: 1.5～30 quality %, and be that 0.1～0.75 material mixes the invention that makes its hardened hardened slag product manufacture method after the stirring with water with respect to the mass ratio of the cigarette ash of the total amount of this blast-furnace slag and cigarette ash.
Moreover, in two kinds of above-mentioned manufacture method, ideal situation is: with respect to (a) particle diameter is that 1.18mm following hot metal pretreatment slag, (b) particle diameter are the following blast-furnace slag of 0.1mm and (c) the total amount of cigarette ash, and the mass ratio of this hot metal pretreatment slag surpasses 0.2.
Again, even also be that ideal situation is in above-mentioned arbitrary manufacture method:, further add at least a kind of material in the group that oxide compound, oxyhydroxide, vitriol and muriate by alkali-metal oxide compound, oxyhydroxide, vitriol and muriate and alkaline-earth metal constitute of being selected from of 0.2～20 quality % to containing in the thing of record with respect to the total amount of this blast-furnace slag and cigarette ash.
Again, even also be that ideal situation is: with respect to this blast-furnace slag, cigarette ash and particle diameter is the total amount of the hot metal pretreatment slag below the 0.1mm, add at least a kind of material in the group that constitutes by naphthene sulfonic acid class and multi-carboxylic acid of being selected from of 0.1～2.0 quality % in the thing further to containing of record in above-mentioned arbitrary manufacture method.
The preferred plan that carries out an invention
Below describe embodiment of the present invention in detail.
At first, in the present invention, use the hot metal pretreatment slag according to following reason as the steel-making slag. promptly:
(1) in hot metal pretreatment, because refining agent does not add MgO, so the original MgO concentration of slag that produces is low, and CaO/SiO 2Low. again, a little contained MgO is also almost with as Ca 2MgSi 2O 7Such high order compound form exists, and free MgO exists hardly.In contrast, the contained MgO of converter slag almost exists with the form of free MgO.Free MgO is different with free CaO, is difficult to generate stable oxyhydroxide by ageing treatment.So, have and can eliminate in the past because the possibility of problems such as the crackle of the hardenite due to the hydration expansion of the free MgO that when converter slag is used as raw material, produces, efflorescence, distortion, intensity reduction.
(2) the hot metal pretreatment slag as described above because CaO/SiO 2Low, and P 2O 5The concentration height is so CaO is mostly with 2CaOSiO 2, 3CaOP 2O 5The form Deng the high order compound exists. thereby free CaO concentration is low.Therefore, because the hydration swelling property due to the free CaO is also low, and has and to eliminate the possibility that is expanded to the problems such as crackle, efflorescence, distortion, intensity reduction of the hardenite of cause with the hydration of the free CaO of steel-making in the slag.
(3) owing to many, the hydration reaction height of fine powder, so itself can replace cooperating the blast-furnace slag fine powder and the cigarette ash of material as other.
(4) because free MgO exists hardly,, pulverize easily more than converter slag so slag itself is soft.
(5) when the hot metal pretreatment slag is fine powder, this carries out hydration reaction each other easily at hot metal pretreatment slag, above-mentioned blast-furnace slag fine powder and cigarette ash, can seek higher intensity.
, the result of trial-production hardenite is: if only adopt the hot metal pretreatment slag, then also insufficient at the effect of the intensity of hardenite and minute crack.
Therefore, inventor's probe to help very much the material of sclerous reaction in the hot metal pretreatment slag be the material of what particle diameter.Found that: particle diameter is that the following substance reaction of 1.18mm is good, the intensity height of the hardenite of gained, and also the generation of minute crack significantly diminishes.Therefore, in the present invention, in the total title complex except water, particularly will limit the contained particle diameter of hot metal pretreatment slag is the content of the following material of 1.18mm.Wherein, better particle diameter is below the 0.425mm, and special ideal particle diameter is below 0.1～0.425mm.Again, this situation does not hinder in the hot metal pretreatment slag that cooperates and contains the size hot metal pretreatment slag also bigger than particle diameter 1.18mm.The hot metal pretreatment slag that granularity is big only illustrates difficult pulverizing the in the process of pulverizing, so because the intensity that itself has to a certain degree is useful as the increment material, so again because active height also is useful as the bonding material.
In addition, said in this application particle diameter is the numerical value of obtaining by size analysis, and methods such as available JIS A1102, JIS A1103 are measured.
In the present invention, in the steel-making slag, there is the steel-making slag of free MgO phase hardly owing to use, and its usage quantity will be limited in suitable scope, do not expand so free MgO does not cause hydration during maintenance in water.The hardened slag product of manufacturing intensity height not only consequently, and minute crack does not exist yet.Further, because also existence hardly of the minute crack due to the dry shrinkage of hardened slag product.
Again, in the present invention, limiting this particle diameter is the amount of the following hot metal pretreatment slag of 1.18mm, on the other hand, and also will be with the SiO that contains of appropriate amount cooperation with its reaction 2Material. this SiO that contains 2Material have latent hydraulicity or pozzolanic reaction is advisable. specifically, use the fine powder of blast-furnace slag singlely or use the mixture of blast-furnace slag fine powder and cigarette ash to be advisable.Below the fine powder of said blast-furnace slag is that particle diameter is the following pulverized slag of 0.1mm in this application, and ideal situation is below the 0.07mm, i.e. the specific surface area of being measured by the Brian method: 3000～5000cm 2It is suitable that/g. makes the broken blast-furnace slag of water as such blast-furnace slag fine powder.The particle diameter that makes blast-furnace slag below the 0.1mm is being owing to make steel the reactive step-down of slag and cigarette ash when surpassing 0.1mm. in addition, the cigarette ash of saying in this application is the same with the blast-furnace slag fine powder to be the SiO that contains latent hydraulicity or pozzolanic reaction 2Material, it generates by burning of coal. in addition, the particle diameter of cigarette ash is unqualified in this application, is below the 0.2mm but general situation is a particle diameter, promptly is equivalent to the specific surface area of being measured by the Brian method: 1500cm 2More than/the g, itself be impalpable powder.When it being replaced particle diameter is the part of the blast-furnace slag below the 0.1mm when using, and improves more with the reactivity of hot metal pretreatment slag, and the intensity after inhibition that the minute crack of hardenite produces and the long-time maintenance improves and becomes possibility.Moreover when using particle diameter as the blast-furnace slag below the 0.1mm separately, its appropriate level is 5～40 quality %.
In the present invention, limit the reasons are as follows of content of hot metal pretreatment slag and blast-furnace slag fine powder as described above:
Be that one of reason is: particle diameter is the containing ratio less than 15 quality % of the following hot metal pretreatment slag of 1.18mm or containing ratio that particle diameter is the following blast-furnace slag of 0.1mm when surpassing 40 quality %, relatively, makes and SiO 2The alkalimetal ion or the balance between supply and demand of alkaline-earth metal ionic of reaction depart from, and the intensity of resulting hardenite reduces; Another reason is: when particle diameter be the containing ratio of the hot metal pretreatment slag below the 1.18mm surpass 55 quality % or particle diameter be below the 0.1mm blast-furnace slag contain quantity not sufficient 5 quality % the time because the SiO that fixedly has composition such as the expansile CaO of hydration in the hot metal pretreatment slag 2Often not enough, so the expansion and the efflorescence of hardenite take place in the resulting hardenite process of maintenance in water, its intensity reduces significantly.
The 1st invention that is the application is to be the following hot metal pretreatment slag of 1.18mm with containing (a) particle diameter: 15～55 quality % and (b) particle diameter be the following blast-furnace slag of 0.1mm: the material of 5～40 quality % mixes the manufacture method that makes its hardened hardened slag product after the stirring with water.
Moreover in mixing stirring operation above-mentioned and water, the water yield and mixer means do not limit especially.But in order to promote the hydration reaction between slag, make muddy and be advisable, when becoming muddy, owing to give flowability, so that forming operation also becomes is easy.Slag class raw material of the present invention all is a fine powder, and water makes mud and pours moulding into and make it with casting mold that hydration hardened method is best suited for.But do not get rid of pie reshaping or the situation of not moulding made from regard to using. in order to make title complex of the present invention become muddy is that the slump is as more than the 3cm, the suitable water yield of using is to account for more than the 6 weight % of title complex, and more suitably the water yield is 8～13 weight %.4～8 weight % left and right sides Shi Qi that account for title complex when the water yield are the pie of the not enough 3cm of the slump.Moreover, because they are according to using the different and different of raw material and cooperation, so determine that according to slump consistancy test the suitable water yield is advisable.
Further, in the present invention, contain SiO in conduct 2Material when using the mixture of blast-furnace slag fine powder and cigarette ash, make that to contain (a) particle diameter be the following hot metal pretreatment slag of 1.18mm: 15～55 quality %, (b) particle diameter are the following blast-furnace slag of 0.1mm: 3～36 quality % and (c) cigarette ash: 1.5～30 quality %, and be 0.1～0.75 material with respect to the mass ratio of the cigarette ash of the total amount of this blast-furnace slag and cigarette ash. being mixed stirring with water after, this title complex make its sclerosis make hardened slag product.
What limit in this wise the reasons are as follows:
At first, be that the containing ratio of the following hot metal pretreatment slag of 1.18mm is that the reason of 15～55 quality % and the particle diameter that makes blast-furnace slag are that reason below the 0.1mm is identical with the reason of having narrated owing to make particle diameter, so repeat no more.Making particle diameter is that the following blast-furnace slag fine powder content of 0.1mm is that 3～36 quality % are because when can obtain high-intensity hardenite when 3 quality % are above; Also then the intensity increase is saturated because its content is if surpass 36 quality % on the other hand, can not get higher effect, and uneconomical. its content of cigarette ash more than 1.5 quality % and with respect to particle diameter be the content of cigarette ash of total amount of blast-furnace slag below the 0.1mm and cigarette ash than being expressed as 0.1 with mass ratio when above, its effect is remarkable.But cigarette ash has tendency than blast-furnace slag fine powder deterioration in the hardening of normal temperature, when the containing ratio of cigarette ash surpass 30 quality % or with respect to particle diameter be blast-furnace slag below the 0.1mm and cigarette ash the total amount cigarette ash content than surpass with mass ratio represent 0.75 the time, then make sclerosis postponement as the integral body of hardened slag product, so at this moment be unfavorable. therefore, the containing ratio of regulation cigarette ash is 1.5～30 quality %, and is that the content of cigarette ash of total amount of blast-furnace slag below the 0.1mm and cigarette ash is than being expressed as 0.1～0.75 with mass ratio with respect to particle diameter.
Further, better in the present invention situation is: with respect to particle diameter is that blast-furnace slag, cigarette ash, particle diameter below the 0.1mm is the total content of the hot metal pretreatment slag below the 1.18mm, the content that makes the hot metal pretreatment slag than surpass the 0.2. that represents with mass ratio this be because: if so, the amount of the amount of the alkalimetal ion of supplying with by the hot metal pretreatment slag and/or alkaline-earth metal ions and contain SiO then 2Material in reactive SiO 2The balance of amount more suitable, the minute crack of hardenite prevents that effect from improving.
The present invention is by resembling cooperation as described above, and the intensity of the hardenite of manufacturing improves and significantly reduces minute crack and takes place.Even more ideal situation is: with respect to particle diameter is the blast-furnace slag below the 0.1mm and the total content of cigarette ash, adds at least a kind of material in the group that oxide compound, oxyhydroxide, vitriol and muriate by alkali-metal oxide compound, oxyhydroxide, vitriol and muriate and alkaline-earth metal constitute of being selected from of 0.2～20 quality %.
Again, with respect to particle diameter is that blast-furnace slag, cigarette ash and particle diameter below the 0.1mm is the total content of the hot metal pretreatment slag below the 0.1mm, and at least a kind of material that is selected from the group that is made of naphthene sulfonic acid class and multi-carboxylic acid that adds 0.1～2.0 quality % also is an ideal.
Promote the sclerosis of hardened slag product to become possibility by at least a kind of material that is selected from the group that oxide compound, oxyhydroxide, vitriol and muriate by alkali-metal oxide compound, oxyhydroxide, vitriol and muriate and alkaline-earth metal constitute that adds more than the 0.2 quality %, because can shorten the needed time of maintenance.Even but addition surpasses 20 quality %, its effect is also saturated, so the upper limit is defined as 20 quality % and is advisable.As this compound, the ideal material can be enumerated Ca (OH) 2, NaOH, CaO, CaSO 42H 2O, CaCl 2Deng.
