Tiivistelmä
The corrosion of steel reinforcement (rebars) in concrete structures is a severe durability and safety problem. One of the most aggressive chemical species which induces such corrosion is the chloride ion via the general mechanism of depassivation of the rebar surface. Chloride ions can diffuse through the solution of pore system in concrete to reach the rebar, thus the assessment of the diffusion coefficient of chloride in concrete is of paramount importance. This paper is the second part of a series of three papers which are meant to provide an overview of experimental methods and theoretical models which are used to predict a concrete materials resistivity to chloride ingress. Part 2 deals with migration methods which major attribute is shortening of experimental time necessary to determine diffusion coefficients.
