Selected experiments for assessing the evolution of concrete, their mechanical safety functions and performance targets: EURAD Deliverable 16.3

Cementitious materials are used in disposal facilities for radioactive waste as a construction material to ensure a safe operation of this facility for example the lining. These materials can also be used to contribute to the containment of radionuclides in the post-closure phase. The required mechanical strength class of concrete is determined by its function. The strength of concrete is determined by the strength of millimetre sized aggregates and the attachment of these aggregates with the cementitious phase in concrete. Only samples of concrete with aggregates are therefore included in this report since Task 2 of EURAD Work Package MAGIC is dedicated to study the chemo-mechanical behaviour at the macro scale i.e. for centimetre and decimetre sized samples.
