PROBLEM TO BE SOLVED: To continuously control the production quantity per a unit time of a concrete mixture by simple constitution.;SOLUTION: A screw 20 is rotatably provided in a cylindrical screw casing 11. A small diameter spiral rotary blade 23, a large diameter spiral rotary blade 24, propeller-like blades 25 and spirally rotary blades 26 are successively provided to the rotary shaft 21 of the screw 20 along the longitudinal direction thereof in a screw feed direction. A mixing material such as rubble or the like charged from the material supply port 12 on the side of the small diameter spiral rotary blade 23 is sent toward the large diameter spiral rotary blade 24 and sent to the propeller-like blades 25 along with the cement charged from a material supply port 14. The mixing material and the cement are mixed with water charged from a material supply port 16, and the concrete mixture is discharged continuously from the side of the spiral rotary blades 26.;COPYRIGHT: (C)2004,JPO
