Abstract:This state-of-the-art report includes a short history on the early development of conveyor belts for transporting and placing concrete. The design of conveyor systems is discussed in relation to the properties of plastic concrete, the delivery rate and the job specifications. Belt widths, speeds, and angles of inclination are considered as they apply to specific site requirements. The three types of concrete conveyors are the portable, feeder, and spreadable types and their particular applications are covered. Field practices in the selection, use and maitenance of the conveyors are described. The economics of belt conveyor placement is discussed. The quality of the in-place concrete and inspection procedures are stressed.
