Abstract: The main objective of the non-destructive evaluation is to obtain information allowing the diagnosis of concrete structures or to quantify input data of durability prediction and/or recalculation models. Among the interesting information to be evaluated on site, water and chloride contents of concrete are relevant pathological features. Therefore, on-site quantification of these physical factors and the evaluation of their spatial variation are very important.

The goal of this research work is related to the application of radar technology for the physical characterization of concrete, especially on the quantitative evaluation of water and chloride contents. The problem has been resolved using statistical approach based on artificial neural network modelling. Experimental database was then implemented, which relates physical characteristics of concrete and radar features. This database has been leaded to develop neural network model of radar measurement inversion able to predict water and chloride contents of concrete made in laboratory.
