Propriétés des bétons incorporant des additions cimentaires alternatives : Durabilité vis-à-vis du risque de corrosion

Massive utilization of cement leads to high CO2 emissions rate. Supplementary cementing materials have been shown to be of great importance considering both concrete durability and sustainable development matters. Extending the list of material used to local by-products constitutes a promising way to further develop green-concretes. This paper deals with the evaluation of the performance of concretes incorporating glass powder, wastepaper fly ash, and sewage sludge ash, when they are subjected to corrosive environments (chloride and carbonation). Concretes (water/binder=0.4 and 0.5) have been cast and their transfer properties have been evaluated in terms of chloride permeability (ASTM C1202), and carbonation kinetic (4%CO2, HR=55%). Influence of the cementitious materials has been evaluated through evolution of these indicators compared to CEM I.
