PROBLEM TO BE SOLVED: To provide an environment and ecosystem friendly concrete product which uses molten slug and metal as aggregate mixed in concrete, has a relatively large size and a large mass, does not look like a concrete product, and exhibits a different appearance, and to provide a method of producing the concrete product. SOLUTION: The following means for finishing the concrete product by taking the environment and ecosystem into consideration is employed. Specifically a form for a product bottom slab using the molten slug and metal as the aggregate is separately formed of an imitation stone product, a natural stone product, or a product made of the other material which constitutes a surface exposed section (irregularity section). After the separate formation, concrete 1 is placed from above an exposes surface, and an irregularity section is embedded and set. If the product is applied to a mound surface or the on-ground slope surface of a river, plant pieces are mixed into planting soil 6 or earth and sand, and irregularities are imparted thereto at the time of finishing. In some cases natural mosses or plant roots are mixed in the soil at the time of finishing, or openings for growing flowering grasses and trees are formed at strategic spots as needed at the time of finishing. If the product is applied to an area in water, local unscreened gravel or cobble stones together with gravel are laid on the bottom. COPYRIGHT: (C)2005,JPO&NCIPI
