<p>PROBLEM TO BE SOLVED: To provide a manufacturing method of a sample capable of displaying progression of deterioration as a model expression while being along an actual environment.SOLUTION: Concrete is solidified in a state in which a recess part 1a, having a shape according to the outer periphery of a reinforcement bar, of a spacer 1 contacts with the reinforcement bar. Consequently, a crack can be formed, where the cross-sectional shape from the surface of a sample to the reinforcement bar becomes even and a predetermined part of the reinforcement bar can contact with ambient air. As the result, a sample capable of displaying progression of deterioration as a model expression while being along an actual environment can be manufactured.</p> |
