Therefore, it was made to contribute to global environmental protection by effectively recycling blast furnace slag.

る。[Aggregate of claim 1] In claim 1, cement is added to rock wool and mixed, and an admixture is added to water and kneaded, and the mixture is rotated in a rotary molding apparatus. Therefore, the heavy cement is located outside of each substantially spherical body due to centrifugal force, and the light rock wool is located inside each substantially spherical body due to the centrifugal force. In other words, rock wool is not exposed on the surface of each substantially spherical body (see FIG. 1). By drying the substantially spherical bodies, the substantially spherical bodies are prevented from sticking to each other. When rock wool is used as an aggregate as it is, kneading and molding of ready-mixed concrete or the like becomes difficult.

が弱くなる。図３参照。[0008] The formed aggregate is filled into concrete or the like in the same manner as the conventional aggregate. Since the aggregate according to the first aspect is a substantially spherical body, when the aggregate is filled in concrete or the like, the aggregates are preferably dispersed mutually without overlapping, and no load is applied to the aggregate itself. That is, the load is preferably dispersed inside the concrete or the like. Also, cement and the like sufficiently enter between the substantially spherical aggregates. See FIG. Incidentally, when the aggregate has a shape other than a substantially spherical body, when the aggregate is filled in concrete or the like, the aggregates may overlap with each other, and the posture of the aggregate and the positional relationship between the aggregate and the aggregate. As a result, a space where cement or the like hardly enters between the aggregates may be formed, or a load may be applied to the aggregates themselves to damage the aggregates and cause a drop inside the concrete or the like. In this case, the concrete or the like becomes weak. See FIG.

イト、モンサルフェートが生成されるものである。In the process of hardening the cement, if calcium ions are given to the aqueous phase to which unstable calcium salts such as tricalcium silicate and tricalcium aluminate, which are the main components of the cement, are added, the water becomes alkaline. It is considered that the mutual hydration reaction proceeds in the phase, and a hydrate of calcium salt is formed. Thus, hydrates produce calcium hydroxide and ettringite, but gypsum is added to the cement to control the quick-setting result, and unstable crystals are formed by the reaction between calcium hydroxide and gypsum. Monsulfate is produced. The reaction structure of the cement is such that the cement hardens into granules and ettringite and monsulfate are generated around the cement.
