Evaluation of Durability of Concrete by Measurement of Permeability for Air and Water
Original language description
Many experts engaged in testing the durability of concrete agree on that the tests of permeability of a covercrete for the air and water can describe indirectly the state of a porous structure of tested concrete. Both from measured values of air permeability coefficient kT using Torrent's method and a value of initial surface absorption measured by ISAT method in compliance with British standard BS 1881:208, it is possible to obtain data for their comparison. As it uses indirect methods of the evaluation of a porous structure of tested concrete under measuring cellules of 10 mm in diameter, it is necessary to perform more measurements on observed section of a structure so the results could be evaluated by statistics methods. The covercrete is considered to be in a depth 50 mm from an outer surface of measured concrete. Since the porous structure contains different volume of the water or vapour, the surface mass moisture is measured simultaneously.
