PROBLEM TO BE SOLVED: To suppress cracks of concrete without using a shrinkage reducing agent of concrete.;SOLUTION: The cracks which are formed due to the relationship between reinforcing bars for bar arrangement and the concrete are suppressed by controlling the expression of a tensile strength of the concrete related to self-shrinkage of the concrete to be higher than the generation intensity of the tensile stress based on a binding force applied to the reinforcing bars, by applying a crack suppression agent to the reinforcing bars arranged inside the concrete structure. The timing of generation of the tensile stress is delayed so that a curve (a) showing a temporal development of the tensile stress of the concrete related to the self-shrinkage of the concrete may always be positioned higher than a curve b showing the temporal development of the generation intensity of the tensile stress based on the binding force applied to the reinforcing bar.;COPYRIGHT: (C)2006,JPO&NCIPI
