Analysis of irradiated concrete

| 2016:239 | Jan Erik Lindqvist, Mathias Flansbjer, Erik Hansson
Irradiation effects on concrete is a subject that has drawn more and more attention, as the possible life time extension, beyond original design life, of nuclear power plants is discussed.

The overall conclusion of the analysis made on drilled concrete cores is that the tests carried out do not indicate any degradation of the mechanical properties. The recorded changes in concrete properties are comparable with what would be expected in a non-concrete aggressive indoor environment. No degradation due to radiation, such as volume changes or alkali silica reactions, could be identified.
