PURPOSE:To produce an adequate agitating effect on concrete and a quick setting agent by equipping both screw runners which are rotatably supported around an axis in a casing and a tubular member connected with the opening end part of the casing. CONSTITUTION:A kneader is equipped with a tubular casing 12 whose one end is opened, screw runners 14 arranged in the casing 12, a tubular member 16 communicated with the casing 12, a supply pipe 18 of concrete and a supply pipe 20 of a quick setting agent. A mixture composed of concrete kneaded in the casing 12 and the quick setting agent is pushed away in the tubular member 16 by successively supplying concrete and the quick setting agent into the casing 12. This mixture is moved through the inside of the tubular member 16 and progressed while resisting frictional force exerted from the wall surface. Therefor transfer of the mixture sent toward the tubular member 16 therefrom is interrupted. Accordingly the number of times wherein the mixture is agitated per a unit time is increased. Adequate agitating effect can be produced on concrete and the quick setting agent without lengthening the casing and the screw runners.
