Determination of the quality of the surface layer of concrete using the TPT method and specification of the impact of humidity on the value of the air permeability coefficient

Original language description

The paper deals with the quality/durability of concrete cove layers and presents results of the experimental works. The work of the team focuses on one of the methods that specify the permeability - and therefore the quality - of the concrete structure cover layers, the TPT (Torrent Permeability Tester) method. The experiments deal especially with the one of the main problems concerned with the air permeability measurement namely with the question - how to take into account the actual humidity of the measured surface during the measurement evaluation. The main aim of performed experiments was to suggest the conversion relation in order to convert the results obtained by the measurement of the permeability using TPT equipment on the material surface with the current humidity into the results determined for the same material with the referential humidity of 3%. The characteristics of pore structure were not taken into account during the data evaluation.
