PROBLEM TO BE SOLVED: To provide a dry shrinkage reducing method of centrifugal molding concrete capable of amply reducing dry shrinkage of the centrifugal molding concrete without using an expansive material or a shrinkage reducing agent.SOLUTION: The dry shrinkage reducing method of centrifugal molding concrete has a centrifugal process to obtain a molded body by centrifugally molding a fresh concrete and a curing process to obtain the centrifugal molding concrete by curing the molded body, wherein the dry shrinkage reducing method of centrifugal molding reduces a dry shrinkage S of the centrifugal molding concrete in a curing process, by changing at least one of a slump value α of fresh concrete, a centrifugal molding acceleration β of centrifugal molding and a centrifugal molding period t in the centrifugal molding process. |
