Original Abstract

The paper deals with various testing methods for evaluating the surface layer (concrete cover) of concrete on which the durability of the whole composite depends. A key parameter for determining concrete permeability is ascertaining pore volume, size and distribution in the material and water and air permeability related to those. The aim of the experiment was to compare the results permeability measurement of the surface layer of concrete using standardized methods (depth of penetration of water under pressure, ISAT, GWT, TPT) with outputs provided by CT. Based on the measurement results CT appears as an inappropriate method for evaluating the permeability of the surface layer of concrete. Circumstances that may limit the test method are described in detail in the article.
