Des pistes de recherche pour diminuer la viscosité des bétons à hautes performances

Abstract : The concrete industry has been undergoing significant change in recent years. Current trends in mix design of high strength and environmentally friendly concretes show that solid volume fraction is progressively increasing. The increase in solid volume fraction has however dramatic consequences on the workability of these new concretes. Although the mechanical performances of hardened concretes are maintained and even improved, the change in mix design is hardly compatible with a good fluidity. To work around this issue, it is possible to use polymers. The article presented here aimed at identifying some potential mechanisms of action of these molecules at the origin of a decrease in viscosity.
