Abstract

This report provides a summary of the results and protocol development for the Task 2 and Task 3 experimental studies. It consists of a set of ongoing (started before EURAD) and new experiments with a selection of mortar/concrete samples in contact with various solutions and atmospheres (CO2), which are representative of different host rocks, with or without microbial activity. Results show the chemical/textural changes (mineralogical evolutions, chemical changes, porosity, transport properties) and their impact on the mechanical properties (Young modulus, compressive/tensile strengths, etc). WP leader and EURAD coordinator decided to merge the D16-6 (Subtask 3-3) and the D16-4 (final deliverable of Task 2) to group all microbiology work. This would facilitate interpreting the microbiology experiments.
