Zusammenfassung:PURPOSE: An extrusion-molding concrete panel is provided to use a waste stone powder is provided to have excellent flexural strength and compressive strength. CONSTITUTION: An extrusion-molding concrete panel comprises 60-80 weight% of a reaction raw material comprising waste stone powder, 10-20 weight% of a filler raw material, 5-15 weight% of a reinforcing fiber, and 0.7-5.0 weight% of a methylcellulose(MC) based on the total weight of the composition. The reaction raw material comprises 40-65 weight% of a silica powder, 15-25 weight% of a waste stone dust, 1-10 weight5 of a silica fume, and 5-20 weight% of a blast furnace slag. The filler raw material comprises 50-75 weight% of silica sand, and 25-50 weight% of a regenerable powder. The fiber reinforcing material comprises 45-65 weight% of wollastonite, 20-40 weight% of a pulp, and 10-20 weight% of a polypropylene fiber.
