Approximation of the bridge deck diffusion coefficient and surface chloride concentration from field data

Original language description

The aim of this work is to analyse the data from in-situ measurements performed on 5 reinforced concrete bridges built between 1937 and 1986, that are a part of the road network in the Czech Republic. The bridges were subjected to the field measurements in order to evaluate the ability of the concrete to protect the steel reinforcement from corrosion, namely the pH and the amount of water-soluble chlorides were evaluated on drilled core samples of concrete. Based on the actual chloride content, the diffusion coefficient and surface chloride concentration were determined. All the data were statistically summarized and the correlations among them were provided. The main focus of this study is to evaluate the non-proportional effect of the amount of chlorides per mass of concrete on the risk of corrosion initiation and to determine the unknown parameters of concrete-diffusion coefficient and surface chloride concentration, based on the numerical model of diffusion.
