Disclosed is a concrete composition capable of forming a hardened concrete body that is superior in strength to a conventional product despite using solid waste as an aggregate. The concrete composition of the present invention comprises one or more of cement, shells, waste plastics, rubber scraps, metal scraps, glass scraps, concrete scraps, ceramic scraps, and rubbles. Crude aggregate made of crushed material and fine ash that has been made harmless by any one or more of coal ash, by-product gypsum, incinerated ash, cinder, dust, dust, sludge, waste soil, and waste sand It includes aggregate, one or more admixtures of blast furnace slag fine powder, fly ash, clinker ash, and silica fume, and glass fiber or carbon fiber reinforced fibers. If the reef block 10 is manufactured from such a concrete composition, the strength of the reef block 10 is improved by the reinforcing fibers in the concrete composition. [Selection] Figure 2 |
