PROBLEM TO BE SOLVED: To provide a method for producing concrete products which can produce a concrete product excellent in load resistance in good work properties by preventing the occurrence of minute cracks caused under external pressure etc. SOLUTION: A fiber sheet is arranged in the clearance between an inner frame and an outer frame, and the inner frame is surrounded by the fiber sheet. Ready-mixed concrete is placed in the clearance, and the concrete product with the fiber sheet embedded in concrete is produced.
