M After the slag has been stabilized and pulverized, the natural slag will be cooled down to 90 ° C, and the processed slag will be taken out of the hot stuffing device, and then the grinding step 6 will be performed. Blast furnace stone, converter stone, etc.) have excellent physical and chemical properties 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 converter stone 2 is oxidation. Although calcium (Ca0), silicon dioxide (Si02), free calcium oxide (F-Ca0), and iron, after cooling, form a solid large block, the slag is stabilized after the above-mentioned hot steam stabilization treatment. The free oxidant in the solution can be quickly hydrolyzed into calcium hydroxide [Ca (() H) 2]. Finally, it can be used for road base course materials, asphalt concrete aggregates, etc. after stabilization and crushing.) = The application scope of slag depletion. If it is further ground into powder, it can be used as a concrete work aid to increase the reuse value of waste resources. Read more in Figure 3. When the components of cement 61, mixing water 62, and sand 64 of concrete 6 are mixed in a certain proportion, it can be added with fly ash and taxi to replace part of the amount of cement 61. The protective additive 66 can be added in due time, except that it has the effect of filling the pores, and the composition of the working additive 7 1241993 5 10 15 66 is similar to that of the cement 61 and is alkaline, so the addition of it can make the concrete 6 show a qualitative state. At the same time, the reaction to the hydration environment will help the concrete 6 accelerate the reaction to increase the early strength of the concrete, that is, as shown in FIG. 4, after the concrete 6 is replaced with the fine sand 63 by the working aid 66, the The strength of days, 7 days and 28 days is better than that without the addition of working aids. Furthermore, there is no fly ash (commonly known as fly ash) in the working aid 66, so no carbon particles remain due to the increase. After that, it will not cause the phenomenon of floating black and foreign powder in concrete 6, and the added amount can replace the amount of sand. This reduces the amount of sand 63. Therefore, the imported sand or machine sand is not enough for the work of concrete 6. Good question, available work Agent 66 fills the sand μ in a coarse state to reduce the water floating amount of concrete 6. Refer to the test data shown in FIG. 5. It can be seen that the concrete 6 has a secondary water content reduced by the addition of a work aid 66, and the work aid 66 It can block the water used for mixing = the state of pore loss formed by sand 63 and sand 63, so the concrete 1 Xinshushe and the property of the concrete are relatively improved to improve the water floating phenomenon of concrete 6 and thus to improve the quality of concrete 6. At the same time, referring to FIG. 6, after adding the auxiliary agent 66 to the concrete 6, according to the test data, it is known that the subsidence shrinkage of the added auxiliary agent 6 is lower than that without adding, that is, ^ effect seal = 62 water loss Therefore, the concrete 6 will not be excessively dissipated due to water, and the concrete 6 is too dry, which can relatively reduce the chance of early cracking. In particular, for low-strength concrete 6, which means that the addition of cement / ^ U 1 is reduced, and in terms of fluidity, after adding work aid 66 to replace part of the sand, the concrete 6 to which work aid 66 has been added Less added ^ 20 5 10 15 20 1241993 Agent 6 6 of the concrete flammable medium, the public τ broke; Shi Ye further proved that the added concrete 6 has better fluidity, and this can be seen in Figure 7㈣66 That is, it was found from the concrete test that the slump test value of concrete 6 to which ^ test data has been added has been reduced from the initial slump additive 66 hours to 12.5 cm · 5, After the centimeter-in contrast, the concrete with no work aid 66 added, its initial happiness is 7 centimeters, and after an hour has elapsed, its financial value has dropped to 8 cm and eight cents, 18 cm. Therefore, it is proved that the concrete with the work aid 66 added Two :, not added power: those who come well have better sex, and it is convenient for guarding to enter. The performance comparison is summarized in the above-mentioned 'the present invention is based on S cold slag: agent', according to the properties of air-cooled slag, suitable material is suitable; ==: after chemical conversion, and then ground into powder to form a working assistant, it should be 2 Additives in concrete will help replace some of the amount of sand ^: can improve: condensate floating water, floating black, floating powder, sand formation, and the effect of litres = soil-induced technical properties, early strength, etc., can indeed Reaching the invention ... But the above is only a preferred embodiment of the invention and can be used to limit the scope of the present invention. It is simple to make the content of the patent month description # in the present invention simple. The equivalent changes and repairs should still fall within the scope of the invention patent.
