PROBLEM TO BE SOLVED: To provide a method for manufacturing a concrete wherein there exists neither problem on dust nor problem on cleaning water when the concrete is directly obtained by a concrete mixer vehicle. SOLUTION: Gravel and sand are directly fed into a concrete mixer vehicle (CV). Cement is fed into a continuous moistening feeding machine (30), wherein it is kneaded and moistened with a specified amount of kneading water which is a set amount necessary for obtaining a specified quality of a concrete, and then, the mixture is fed into the concrete mixer vehicle (CV). Then, the inside of the continuous moistening feeding machine (30) is cleaned with remaining kneading water used for moistening and the kneading water used for cleaning is fed into the concrete mixer vehicle (CV).
