<P>PROBLEM TO BE SOLVED: To provide a dry shrinkage prediction method of concrete for, before performing long-term drying of the concrete, accurately predicting the dry shrinkage of the concrete after the long-term drying. <P>SOLUTION: This dry shrinkage prediction method of concrete includes: a mixing process of obtaining a mixture by mixing cement, fine aggregate, coarse aggregate, and water; a hardening process of hardening the mixture to obtain concrete; and a prediction process of predicting dry shrinkage after the lapse of a drying period ranging from 150 to 360 days from the drying shrinkage after the lapse of a drying period ranging from 6 to 57 days of concrete and a measurement value of a mass reduction rate in the hardening process. <P>COPYRIGHT: (C)2012,JPO&INPIT |
