Measurements of the effective diffusion coefficient, De, of 222Rn in concrete are important for accurate determination of transport mechanisms and computer modeling of radon entry into structures. A method for in-situ determination of De as well as the emanation fraction, F, is described. It is ...
Coefficient of VariationCarbonic Gas CO_2Reinforced concrete is the construction material widely used in civil engineering. However, knowledge of its long-term performance and the uncertain impact of the environment on his behaviour make it difficult to accurate assessment of the durability of ...

Generally, concrete with high resistance to the marine environment should have high compressive strength, a low chloride diffusion coefficient ( D C ), and a high acceptable chloride level (Ac). Considering all parameters simultaneously, this study evaluated the degree of fly ash concrete durability...
of diffusion. An overview is given e.g. by[54]. Generally, the water vapor diffusion coefficient depends on the actual concrete mix composition, microstructure and boundary conditions (mainly humidity and temperature).Bazant and Najjar[55]found that the water diffusion coefficient decreased by 10 ...
