Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for predicting dry shrinkage of centrifugal molding concrete for a long period of time.SOLUTION: The present invention relates to a method for predicting dry shrinkage of centrifugal molding concrete comprising: a step of mixing cement, fine aggregate, coarse aggregate and water to obtain a kneaded mixture; a step of centrifugally molding the kneaded mixture to obtain a molded body; a step of curing the molded body to obtain concrete; a step of predicting dry shrinkage of the concrete after a lapse of 150-360 days of dry period based on measured values of dry shrinkage and mass reduction rate after a lapse of 6-57 days of dry period.
