PURPOSE: To obtain a concrete charging method, which is excellent in productivity and suitable for the mass-production of concrete product.

CONSTITUTION: A plurality of forms 12 for molding concrete product are successively and intermittently conveyed to and arranged at a plurality of the predetermined positions P1 and P2. At the predetermined positions P1 and P2, concrete charging devices 23a and 23b are respectively arranged. At the first predetermined position P1, the required amount, which is less than the necessary amount, of ready-mixed concrete is charged in the form 12. Next, at the second predetermined position P2, ready-mixed concrete is additionally charged in the form 12 by the amount, which satisfies the necessary amount in total with the previously charged amount. Further, at the predetermined positions P1 and P2, the charging action times of the concrete charging devices 23a and 23b are overlapped so as to simultaneously charge ready-mixed concrete in the respective forms 12.
