Abstract

Results of a complementary experimental study of the mechanical, thermal, and hygral behavior of a normal strength overlay concrete are presented. In particular, the evolution of the cube compressive strength, the Young's modulus, the autogenous shrinkage strain and the temperature are presented. Furthermore, the water sorption behavior and different sealing techniques of specimens are investigated. Together with the experimental results from previous studies, a comprehensive and consistent set of measurement data for a particular overlay concrete is now available. It will be used for calibrating and validating multiphase concrete models, aiming at the numerical simulation of the placement of concrete overlays.
