    摘要: The above objectives are reached thanks to a binder composition comprising:
    a. between 1% and 30% in dry weight of at least one lime source;
    b. between 5% and 75% in dry weight of ground granulated blast furnace slag;
    c. between 20% and 90% in dry weight of at least one filler;
    d. between 0.1% and 5% in dry weight, relative to the total weight of components a, b and c, of SO 3 ;
    e. between 0.1% and 1% in dry weight, relative to the total weight of components a, b and c, of at least one water reducer polymer;
    f. between 0% and 2% in dry weight, relative to the total weight of components a, b and c, of at least one accelerator different from d.;
    said ground granulated blast furnace slag being a particles mixture of:
    - between 10% and 100% in weight, in respect with the total weight of the ground granulated blast furnace slag, of particles having a d 50 greater than or equal to 1µm and strictly less than 5µm,
    - between 0% and 90% in weight, in respect with the total weight of the ground granulated blast furnace slag, of particles having a d 50 greater than or equal to 5µm and preferably less than 15µm, said filler being a particles mixture of :
    - between 10% and 90% in weight, in respect with the total weight of the filler, of particles having a d 50 greater than or equal to 0,05µnn and strictly less than 8µm, and
    - between 10% and 90% in weight, in respect with the total weight of the filler, of particles having a d 50 greater than or equal to 8µm and strictly less than 200µm.
