Aging of cementitious materials

Start date 01/01/2010
End date The project is closed: 31/12/2014

Deposition of low and intermediate level radioactive waste (LILW), involves processes with duration of up to 100000 years. This research project deals with ageing process of cementitious materials in a perspective of hundreds and thousands years. As it is risky to use empirical models for extrapolation of performance data from relatively short term experiments, a mechanism-based (chemo-mechanical coupled) model for safer prediction of longevity of concrete in storage facilities for nuclear waste is needed.

The project work involves thermodynamic modeling, development of accelerated aging tests, physical, chemical and mineralogical characterization of young and aged cementitious materials, including mechanical, transport (diffusivity) properties, binding (adsorption) capacities and surface complexation (charging) behavior.

The project is carried out by the Divison of Building Technology, research goup Building Materials.
