Abstract: A micro-mechanical scheme has been coupled to a hydration model in [1] so as to investigate the instantaneous mechanical properties of a concrete. That scheme is extended to aging linear viscoelasticity so as to estimate… read more here.

DOI: 10.1080/19648189.2017.1280417
Abstract: The prestressed concrete confinement vessel is the third and last barrier in French Nuclear Power Plants (NPP). In case of a severe accident (loss of cooling agent of the reactor for instance), pressure and temperature… read more here.
