Abstract:
Basic principles of movement of plastic concrete through pipe and hose distribution system discussed. Laminar and plug flow described, with limiting velocities under various conditions. Describes relation between rate of concrete delivery, pipe size, and velocity. Provides extensive theory and data for constructor and engineer.
