Some manufacturers have proposed the addition of fly ash, or 10 stone furnace powder, which is cooled by water quenching and then ground into fine powder. Taking the above-mentioned furnace stone powder 15 as an example, it contains a high amount of glassy and has potential cementing ability. Therefore, after grinding into fine powder and mixing it with cement u, it will have a "bu Zuolan" effect, forming a cement clinker-like Hydrate C_s—H colloid, so it can replace part of the cement u, but it belongs to the three types of furnace stone 15 15 gas-cooled blast furnace hearth, converter hearth stone and electric arc hearth stone, which do not have this characteristic Therefore, special attention should be paid to the selection, and the exclusion of the unsuitable furnace stone powder 'is caused by the replacement of the cement 11 portion, which reduces the amount of addition. In addition to reducing the flowability of the concrete, it can easily cause fly ash or furnace stone powder 15 The impurities contained in one will float as the water floats on the surface of concrete i.

In addition, the sand 13 mixed in concrete i has been in short supply due to long-term use of natural sand. Therefore, the current industry has replaced it with imported sand (such as large sand) and machined sand. The machine sand and so on are too thick 5 10 15 20 200521100, so the water content of the concrete 1 during mixing cannot be blocked by the sand 13, which causes the continuous sealing and floating water of the mixing water 12 to be too much. Emerging in the surface layer, and the production is prone to pores due to floating water, turtles mi mi extremely condensate soil 1 words, itching, contraction and other phenomena, so there is also a problem of poor workability for mixed soil 1. [Summary of the Invention] The purpose of 纟 ^ month is to provide a method based on U gas-cooled furnace cleaning, which is to stabilize the slag to achieve the reuse of waste resources, concrete floating water, floating M, "... use quality, and improve the effectiveness of the invention: gas: 2: 7 sand and low early strength. The method, which includes concrete working aids in sequence, combines the steps produced by the steelmaking process first. The slag is collected; the other step is to blast the furnace **, person, and # ㈣, and to perform another cold step ... The following and form a block: Λ cooling treatment, the surface temperature of the slag is reduced to 5.0. Powder, and after the grinding step of tapping, the blocky furnace smash is researched and then the auxiliary is added; of course, and depending on the nature of the slag, it can be decomposed into stable ΓΓ to make a small amount of free oxidation in the slag quickly Water 1 The previous steps will help the manufacturing of Γ work aids, and at the same time, it can replace some of the sand's secondary work: Assist: When mixed with concrete, the work will help t 'straw to reach waste when it is added. In addition to resource reuse, the same, floating powder, from: = improve the pores of sand supplement Concrete floating water, floating black, and work travel, so it can improve the use of concrete quality and fluidity and other effects, the addition also has the ability to improve the density and early strength of concrete to prevent early cracking of concrete. 5 200521100 [Implementation Mode] The foregoing and other technical contents, features, and effects of the present invention will be clearly understood in the following detailed description of the preferred embodiment with reference to the drawings. $ Referring to FIG. 2, the present invention is based on an air-cooled slag A preferred embodiment of a method for making a concrete work aid includes an aggregate step 2, an air cooling step 3, a slag stabilization step 4 and a grinding step 5; Taking air-cooled slag as the main body, and for air-cooled slag, it can be classified as air-cooled blast furnace stone, air-cooled converter stone, electric furnace stone slag, and electric furnace stone to reduce spring slag. This embodiment uses converter stone steel slag as an example. , The workers first collect the slag generated in the converter steelmaking process in large slag buckets, and then pack them into a plurality of stain trays, and must apply a mold release agent before each slag tray is filled to facilitate The demoulding operation after the slag is hardened. In addition, the slag is separately packed on the slag trays. Therefore, the slag on each slag tray can be maintained with a specific size and weight. In step 4 of the air cooling, the slag in each slag tray Carry out air cooling and cooling treatment 'to reduce the temperature of the furnace wire to below 50 rc and reduce the slag: At the same time,' the surface of the slag stacked in the slag tray is cooled to form a block. In the furnace, in the stabilization step 5, The steel slag in the converter is not stable. Therefore, it is necessary to perform step 5 of money conversion, which is about to complete the air-cooling step. • The furnace collapse of 4 will be carried to the Andinghua treatment plant. Then, take out the block-shaped and naturally cooled furnace rupture from each plate, and directly put it into a hot stuffing device (not shown in the figure) to perform hot steam curing and stabilization treatment, so that the hot stuffing device is inside the hot stuffing device. Maintaining _ set temperature and power, 6 5 10 15 Food reading chart animal fart condensate 200521100 The free oxide contained in the furnace can be quickly hydrolyzed and digested into stable chlorine oxidation. Each 'makes the free oxidation content less than 3%' And achieve excellent stabilization results, then , Such as thermal effects nausea move into the collapse strength of the furnace increases, with optional free calcium oxide in the slag as calcium hydroxide hydrolysis process, arising from the ^

After the furnace has been stabilized and pulverized, it is allowed to naturally cool down to 9 generations, that is, the processed slag can be taken out of the hot stuffing device, and then the grinding step 6 is performed. Because of the slag (such as Blast furnace stone, converter stone, etc.) have excellent physical and chemical characteristics similar to natural sand stone, wear resistance, high temperature resistance and corrosion resistance. Taking the converter stone in this example as an example, the main component of the converter stone is (Oxidized coffee), stone dioxide (called free state: chemical about '〇), and iron, etc. Although solid large chunks are formed after cooling, but after the steam and health treatment as described above, the furnace ruptures freely. Oxygen can be rapidly hydrolyzed into H and oxidized to about [Ca⑽]. Finally, it can be used for stabilization and pulverization: ^ It can be used as road substrates, asphalt concrete aggregates, etc., and it can be used as a resource in 4 large furnaces. If it is further advanced-it will be ground into powder II. P: As a concrete work aid, use the components of cement 61, mixing water 62, sand ^ uncle 枓 64, etc. to increase waste resources, and then mix in a fixed proportion. When mixing, it can be added with fly ash or Nanri ^ 5 to replace the part In addition to the amount of cement 61, in addition, it also adds "work aid 66", in addition to the pore filling effect, and the composition of the work aid 20 5 10 20 200521100 66 is similar to that of cement 61 and is alkaline, so After its addition, it can make the concrete 6 appear sorrowful, and at the same time, it will help the concrete 6 accelerate its reaction to the hydration environment to improve the early strength of the concrete. That is, as shown in FIG. 4, concrete 6 is replaced with a work aid 66. After the amount of sand 63, the strength of the concrete 2 at 3 days, 7 days, and 28 days is better than that without the work aid 66. Furthermore, the work aid 66 does not contain fly ash (commonly known as fly ash). ) Substance, so no carbon particles + remain, so after adding it will not cause the phenomenon of darkening and floating powder in concrete 6, and the added amount can replace the amount of sand, so as to reduce the amount of sand 63. Imported sand or machined sand has poor working performance for concrete 6. It is possible to use working aid 66 to fill the sand ^ partial rent state, so as to show that the concrete 6 is added with working aid 66, making Float: the amount is reduced and the work As an auxiliary agent 66, it can block the contained water 62 and the state of pores formed between the sand 63 and the sand 63. Therefore, the compactness of the concrete is also relatively improved, α improves the water phenomenon of the concrete 6 #, and then: The quality of the concrete 6 is also referred to FIG. 6. After adding the concrete 6 additive: After the additive 66, it can be known from the test data that the additive of the additive 6 = soil 6 # subsidence shrinkage, which is lower than that without the addition of φ. Effective sealing; combined water 62 is lost, so concrete 6 will not be excessively dissipated due to water, and d concrete 6 is too dry, relatively, it can reduce the chance of early cracking. In particular, for low-strength concrete 6, that is to say, the addition of cement M is reduced, and in terms of fluidity, the work aid 66 is added to replace part of the sand (the concrete 6 to which the work aid 66 has been added is less Add work
