Abstract :
[en] This paper analyses the influence of Recycled Concrete Aggregates (RCA) on durability through a study of transfer properties of concrete, using a coupled approach consisting of experimental testing and numerical modelling. Experimental tests performed on concrete made from Natural Aggregates (NA) or RCA conclude that Recycled Aggregate Concrete (RAC) is more porous than its NA-based counterpart. Its water absorption is also superior while its intrinsic permeability is slightly lower than regular concrete. A coupled thermo-hydraulic numerical model, based on non-linear finite elements and constitutive equations, is developed. These constitutive equations rely on properties determined experimentally, on concretes made in the laboratory. The results disclose that RAC has a saturation degree constantly above the one of regular concrete.
