PERMEABILITY OF CONCRETE AS A METHOD FOR CALCULATING THE LIFE EXPECTANCY OF REINFORCED CONCRETE COMPONENTS . PROTECTION OF CONCRETE. PROCEEDINGS OF THE INTERNATIONAL CONFERENCE HELD AT THE UNIVERSITY OF DUNDEE, SEPTEMBER 11-13, 1990

The close relationship between the specific permeability coefficient and the specific diffusion coefficient simplifies the assessment of the structure of concrete and its ability to resist various external agressive agents. Carbonation is presupposed to act as a factor harmful to reinforced concrete and this period of the life expectancy can be theoretically calculated in dependance of the permeability coefficient. Permeability of concrete determines also the transportation of oxygen required for corrosion after the initiation of corrosion. The design problem is to ensure that the time from construction to the occurrence of unacceptable corrosion damage is greater than or equal to the design life of the structure. Laboratory results are reported in order to evaluate the influence of different surface coatings. (Author/TRRL)
