ABSTRACT:
A method of mixing cementitious material, liquid, and aggregate uses a cementitious material/liquid premixer to form concrete. The method of mixing includes: dispensing cementitious material through a material outlet; receiving the cementitious material into an enclosed screw conveyor assembly and moving the cementitious material with said screw conveyor toward a conveyor outlet; introducing liquid into the screw conveyor so as to deposit a quantity of the liquid into the cementitious material as the cementitious material is moving toward the conveyor outlet; agitating and mixing the liquid and the cementitious material together by movement of the screw conveyor, thereby forming a flowable slurry; and discharging the flowable slurry from the conveyor outlet into a final product mixing chamber where aggregate material will be introduced.
