摘要： The invention concerns a binder composition comprising:
a. between 1% and 30% in dry weight of Portland cement, lime or a mixture thereof;
b. between 1% and 40% in dry weight of ground granulated blast furnace slag ;
c. between 20% and 50% in dry weight of at least one pozzolanic material;
d. between 20% and 65% in dry weight of at least one filler;
e. between 0.5% and 10% in dry weight, relative to the total weight of components a, b c and d, of at least one activator;
f. between 0.05% and 1.5% in dry weight, relative to the total weight of components a, b, c and d, of at least one water reducer polymer;
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 0,05µm 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.

摘要： The invention concerns a hydraulic binder composition comprising:
A) a mixture of:
A-1) between 20 dry wt% and 95 dry wt % of at least one steel making slag,
A-2) between 4 dry wt % and 79 dry wt % of at least a slag different from A-1, and/or at least one pozzolanic material and/or at least one inert filler,
A-3) between 1 dry wt % and 25 dry wt % of at least one co-binder, preferably a clinker source and/or a lime source different from A-1 and A-2,

B) between 0.01 dry wt % and 10 dry wt %, relative to the total dry weight of A, of at least one steel making slag accelerator,
C) between 0.1 dry wt% and 5 dry wt%, relative to the total dry weight of A, of at least one alkali activator for reacting A-1, A-2 and/or A-3 with water, C being different from B and chosen among alkali mineral salts and mixtures thereof,
D) between 0.1 dry wt% and 2 dry wt%, relative to the total dry weight of A, of at least one fluidification agent.
