International audience; Slag is increasingly used for replacing a part of clinker. The addition of slag modifies the hydration process and so the physico-chemical properties (such as porosity, transport properties) of cementitious materials. Indeed t

International audience; The physico-chemical properties of cementitious materials, such as transport properties or porosity are established during the hydration process. The latter which involves dissolution and precipitation reactions, is characteri

Cements with high slag content are currently studied as possible candidate for nuclear waste containment materials. In this context it is important to know their microstructure and the transport properties (permeability and diffusion) of the gases th

International audience; Methanogenic archaea are able to convert CO2 and H2 into CH4. This metabolic activity is of uttermost importance to understand the feasibility to store green hydrogen in gas reservoir by transforming it into more stable methan
