。(Problem B to be Solved by the Invention) As mentioned above, concrete, which is the main raw material for concrete blocks, is made up of fine aggregates, coarse aggregates, and in some cases admixtures and reinforcing materials that are bonded to each other firmly. Cement is blended as a material, and this cement mainly uses raw materials such as limestone and clay, and is produced through multiple processes such as mining, firing, crushing, and classifying the raw materials. Therefore, in producing ordinary Boltland cement, not only is a large amount of limited resources that exist in nature consumed, but there is a risk that they will eventually become depleted.
Since it is produced through multiple steps, there is a problem in that it consumes a large amount of energy such as oil, coal, and electricity.
さらに、普通ボルトランドセメントは、上述したように

云う問題がある。Furthermore, since ordinary Boltland cement is produced through multiple steps as described above, there is a problem in that the cost is high.

て硬化する特性がある。An object of the present invention is to provide a slag block that can be formed into blocks using steel slag as the main raw material, which can save resources and energy. (Means for Solving the Problems) In order to achieve the above-mentioned objects, the slag block of the present invention is obtained by kneading and molding predetermined amounts of a binder, fine aggregate, coarse aggregate, and kneading water. The block is a steel slag obtained by crushing and crushing all of the binding material, fine aggregate, and coarse aggregate, and the steel slag as the binding material is a steel slag that is a mixture of blast furnace slag and steelmaking slag. It is configured using (Function) If the rapidly cooled blast furnace slag as the blast furnace slag which is the binder of the present invention is made fine by spraying pressure water or high pressure air on the flowing high temperature molten blast furnace slag, the cooling rate will increase due to radiation and heat transfer. It is then rapidly cooled and obtained as slag with a high vitrification rate. Second in this glass award, cold slag is highly active and has the property of forming hydrates and hardening in the presence of an alkaline aqueous solution.

得られる。On the other hand, steelmaking slag, which is also used as a binder, contains a large amount of soluble calcium, which becomes an alkaline aqueous solution when dissolved. Therefore, these properties are used as a binding material for slag blocks. Then, steel slag that has been crushed and sized to a predetermined size as fine aggregate and coarse aggregate, and pulverized quenched blast furnace slag and steelmaking slag as binders are added, and when mixed with mixing water, it becomes fluid. A concrete-like slag fluid is obtained.

ｃｊ／ｇ以上とすることが好ましい。The quenched blast furnace slag can be obtained by various methods, one of which is generally known as granulated blast furnace slag, which is obtained by simultaneously refining and cooling high-temperature blast furnace molten slag with pressure water. The typical steelmaking slag is the slag generated in converters, electric furnaces, etc. In addition, the ratio of slag as a binder is 20 to 90% granulated blast furnace slag and 1% steelmaking slag.
It is desirable that it be between 0 and 80%. CaO in the liquid phase existing in the incoming lag fluid is dissolved from SiOt,8l,0, which is dissolved from the granulated blast furnace slag.
, etc. to form a hydrate and solidify and harden, so the amount of steelmaking slag to be used should be set so as to ensure the amount necessary for this reaction. Furthermore, the granulated blast furnace slag contains C
It has a so-called latent hydraulic property that hydrates and solidifies when stimulated by an alkaline aqueous solution such as an aO solution. Utilizing this latent hydraulic property, it plays the role of a binder as a substitute for cement, but in order to greatly express the latent hydraulic property, the specific surface area of granulated blast furnace slag particles is 3000.
It is preferable to set it as cj/g or more.

る。Steelmaking slag such as converter slag and electric furnace slag is used as the alkaline stimulant necessary to stimulate the above-mentioned tidal hydraulic properties. Since this steelmaking slag contains a large amount of soluble calcium, when this steelmaking slag and kneading water are kneaded, a highly concentrated alkaline aqueous solution of Ca (OH) z can be obtained. Therefore, when pulverized granulated blast furnace slag and milled slag are used as a binder, and fine aggregate made from steel slag, coarse aggregate, and kneading water are kneaded together, it is possible to mix the fine aggregate, coarse aggregate, and kneading water together in an alkaline aqueous solution with a pH of 12 or higher. The binding material reacts to form a hydrate, which provides approximately the same strength as when cement is used.

に使用することができる。Further, in order to promote dissolution of the steelmaking slag, the specific surface area of the steelmaking slag particles is preferably 3000 cj/g or more. Furthermore, if steelmaking slag contains harmful amounts of free lime, it will absorb water and produce Ca (OH).
! The volumetric expansion that occurs when the product changes to slag may cause the product to expand and collapse. Therefore, this type of converter furnace slag and electric furnace slag must be aged beforehand to eliminate harmful amounts of free lime (Ca(OH)). t). Although the steel slag as a binding material has been described above, other fine aggregates, coarse aggregates, etc. that constitute the slag block will be described below. As raw materials for these fine aggregates and coarse aggregates, blast furnace slag or steelmaking slag that has been crushed and sized to a predetermined size, or a mixture of both can be used.

る。Among blast furnace slag, fine aggregate made by adjusting the particle size of granulated slag is
As mentioned above, it has increased hydraulic properties, so it has excellent adhesion to binding materials, and hardens over a long period of time due to its own binding strength.
It has properties that increase the strength of the product. In particular, when applying the product block to underground objects, etc., if the product block can maintain an appropriate level of humidity, this characteristic is utilized to the maximum.

行っている。Also, is the slowly cooled blast furnace slag fine bones? This slow-cooled blast furnace slag can be used as both coarse aggregate and has many irregularities on the particle surface and a large bonding area with the binder.
In particular, it has the advantage of increased bending strength. Incidentally, the products obtained by adding and kneading the above-mentioned binder, fine aggregate, coarse aggregate, and kneading water, followed by molding and curing may have different product weights even if they have the same shape. In order to adjust the weight of these products, we have traditionally

(Hereinafter, blank space) Next, the test results of the slag concrete of the present invention containing steel slag and conventional concrete are shown in Table 3 below. (Hereinafter, blank space) The unit of the above compressive strength is kgf/ca.
In addition, the above test results are 10cm in diameter and 20C1m in height.
The test beads were cured in water at 20°C, and the above values are the average values of the three test pieces. As is clear from Table 3, even when comparing the slag concrete of the present invention formed laterally with steel slag and the conventional concrete using cement as a binder, there is no difference in compressive strength etc. (invention According to the present invention, a slag block obtained by using steel slag, which is a mixture of blast furnace slag having latent hydraulic properties and steelmaking slag containing a large amount of soluble calcium, as a binder, This is a high-quality product with the same compressive strength and bulk specific gravity compared to the concrete block used as a binding material. In addition, since steel slag generated in the steel industry is used as a binder and aggregate, resource and energy savings can be achieved, and an inexpensive slag block can be obtained.
