PROBLEM TO BE SOLVED: To provide a method for producing an extruded cement plate in which, even in the case chip pieces and a defective extruded cement plate are generated in the production process of an extruded cement plate, deterioration in production efficiency is hardly caused without requiring disposing of them.SOLUTION: The method for producing an extruded cement plate is composed of a production process including: a step of extrusion-molding a hydraulic molding material 2 to form a molded body 4 having a hollow hole 3; and a step of feeding bubble-containing cement 5 to the hollow hole 3. The production process further includes: a step of recycling an uncured defective extruded cement plate 45 generated in the production process and mixing the same with the hydraulic molding material 2. |
