Evaluation of Scaling Resistance for Concrete structure by Rapid Air Permeability Test

本研究开发适用于混凝土结构的快速透气性测试装置，并探讨影响透气性指标的各种因素。结果，明确了确保实验灵活性和再现性的测试条件。此外，通过对空气渗透性指标与结垢阻力之间关系的研究，说明了空气渗透性指标作为结垢阻力评价指标的可能性。

In this study, the Rapid Air permeability test apparatus applicable to a concrete structure was developed and various factors which have on air permeability index were examined. As a result, the test condition which secures experimental flexibility and reproducibility was clarified. Moreover, a possibility that air permeability index could apply as an evaluation index of scaling resistance was shown, by investigating the relation between Air permeability indexes and scaling resistance.
