Three NDT Methods for the Assessment of the Concrete Permeability as a Measure of Durability

摘要

This contribution deals with the extensive measurements of the air permeability using TPT (Torrent Permeability Tester), of the water permeability by GWT (German Water Tester) and ISAT (Initial Surface Absorption Test) methods. The measurements were complemented with the determination of compressive strength. By the combination of these methods and their evaluations, it is possible to obtain the data enabling an assessment of the concrete cover quality from the viewpoint of durability on the high level of relevance.
