EURAD - D16.5 - Initial synthesis of experimental data for calibration and validation of macroscopic models in Task 4

This report provides an initial synthesis of experimental data obtained in Task 3, which are devoted to calibration and validation of multiscale models developed in Task 4.

The major achievements of the Task 3 in the WP-MAGIC described in the report include:

• The microstructure evolution of cement paste due to chemical degradation is characterized.
• Development of a new experimental device in view of conducting uniaxial and triaxial compression tests with micro-tomography monitoring.
• Realisation of uniaxial and compression tests with micro-tomographic imaging on mortar samples subjected to three different states of carbonation.
• Non-uniform distributions of strains in the tested samples are determined by using a digital voxel correlation method (DVC). 
• The basic mechanical behaviour of mortar and impacts of carbonation processes are analysed.
• The evolution of mechanical properties is estimated for HCP and concrete by micro-indentation measurements.

The presented work is a collective effort of the several research groups, in particular CNRS/LaMcube, IRSN and PSI.
