METHOD FOR PRODUCING CONCRETE SEGMENT

摘要

PROBLEM TO BE SOLVED: To efficiently produce a concrete segment having a specific property. SOLUTION: A method for producing the concrete segment includes a process for installing a cylindrical segment form concentrically in the centrifugal drum of a centrifugal molding apparatus and a packing process for packing concrete in the segment form while the centrifugal drum is rotated in which a plurality of different kinds of concrete are packed one after another in the segment form so that the concrete to be molded centrifugally has a plurality of layers.
