The present invention uses a three-dimensional metal reinforcing aggregate as an aggregate in producing a common ready-mixed concrete according to its object of use in producing the ready-mixed concrete and a mortar. Since it is the three-dimensional metal reinforcing aggregate, it is a technique to enhance the external pressure, internal pressure and tensile strength when the ready-mixed concrete is hardened and solidified. Since the three-dimensional metal reinforcing aggregate is forced into between an aggregate and an aggregate in the ready-mixed concrete, the aggregate and the aggregate are further bound, thereby enhancing the internal pressure, the external pressure and the tensile strength. For example, if split, crack and the like is generated on the concrete body near the cold joint of the placed concrete, the conventional concrete body leads to drop thereof and causes an accident. However, with the concrete body using the inventive three-dimensional metal reinforcing aggregate as the aggregate, even if the crack or the like is generated thereon, the three-dimensional metal reinforcing aggregate is coupled and connected with a variety of aggregates in the concrete body. Therefore, even if the split, crack or the like is generated thereon, it never leads to the drop. Consequently, it is a technique of high strength that can prevent the accident of concrete lump drop due to the cold joint and that also intends safety for a variety of structure of public works and buildings. It is an earthquake-resisting concrete that can construct structures such as bridges, dams, tunnels, buildings, airports, harbors and the like. It is characterized by using and mixing and kneading a three-dimensional metal reinforcing aggregate as an aggregate in manufacturing a ready-mixed concrete.
