To reduce the environmental impact of cement production and to save energy, one solution is to replace clinker by supplementary cementitious materials (SCM) to design binary or ternary binder. However, the reaction kinetics of SCM are slower than clinker, leading to a delay in the development of the microstructure. Therefore, this study assesses the impact of drying impact at early age for concretes containing this kind of binder. Concretes with a W/B = 0.35 and ternary binder content of 350 kg/m3 were assessed. The binders were composed of: 20% Ordinary Portland cement (OPC)/ 30% GGBS1/50% Limestone filler, 20% OPC/30% GGBS2/50% Limestone filler and 25% OPC/25% GGBS2/50% Limestone filler. The comparison was made with a reference concrete containing 300 kg/m3 CEM III/A and a W/B = 0.50 (XC4 according to EN 206 + A2/CN:2022). The concrete specimens were cured for 1, 3, 7 and 91 days. Then they were carbonated in accelerated conditions ([CO2] = 3%), according to NF XP P18–458. In addition to the carbonation kinetics, mercury intrusion porosimetry was performed before and after carbonation. The results showed that for a similar compressive strength class, concretes cured 91 days and containing ternary binders had a better resistance against the carbonation than the reference. For the concrete containing the ternary binder (20% OPC/ 30% GGBS1/50% Limestone filler), the effect of drying at early age on the carbonation kinetics was similar to the reference concrete.
