PROBLEM TO BE SOLVED: To provide a method that is a production method of a concrete product by centrifugal molding, and in which a solid content amount included in sludge water can be reduced, and a concrete product in which an inner surface state is favorable can be provided.SOLUTION: Provided is a production method of a concrete product by centrifugal molding. The production method of a concrete product is characterized in that during a medium speed centrifugal molding process, after an objective revolution speed of the process is attained, preferably after a medium time between when an objective revolution speed of a medium speed centrifugal molding process is attained and when a medium speed centrifugal molding process is completed, an aqueous liquid including potassium carbonate is input to a concrete inside face during centrifugal molding, and is enforced. |
