A binder composition including: (a) between 10% and 49% in dry weight of Portland cement, lime or a mixture thereof; (b) between 10% and 49% in dry weight of at least one pozzolanic material; (c) between 21% and 80% in dry weight of at least one filler; (d) between 0.1% and 10% in dry weight, relative to the total weight of components (a), (b) and (c), of at least one activator; (e) between 0.05% and 1.5% in dry weight, relative to the total weight of components (a), (b) and (c), of at least one rheology enhancing admixture. The filler is a particles mixture of: between 10% and 100% in weight, in respect with the total weight of the filler, of particles having a d50 greater than or equal to 0.05 m and strictly less than 8 m, and between 0% and 90% in weight, in respect with the total weight of the filler, of particles having a d50 greater than or equal to 8 m and less than 200 m.
