PURPOSE: To form a concrete structure which is excellent in strength and quality by small friction and a small load on a motor by a method wherein ready-mixed concrete is kneaded to be used for placing with a shuttering or the like, and kneading operation and feed operation with a stirring vane can be smoothly lightly carried out without irregularities to improve operating efficiency. CONSTITUTION: A rotor 8 is rotatably provided in a kneading container 1 by centering a rotary shaft 4 driven with motors M2 , M3 . A plurality of pieces of a stirring vane 11 wherein a front surface forms almost an triangle having an inclined part, and a spiral is formed by a specific pitch P and a specific torsion angleβ, are formed on a peripheral surface of the rotor. Thereby, ready- mixed concrete is stirred, and discharged.
