Abstract: A hydraulic composition includes in relative parts by mass with respect to first Portland cement: 100 parts of a first Portland cement the particles of which have a D50 between 10 and 25 μm; from 25 to 76 parts of a second Portland cement the particles of which have a D50 between 0.5 and 6 μm; from 85 to 200 parts of sand; water; the water content being such that the hydraulic composition includes from 170 to 250 kg of water per cubic metre of hydraulic composition; the volume distribution of particle size of the first Portland cement and of the second Portland cement being further such that the ratio D50 of the first Portland cement/D50 of the second Portland cement is greater than 2.
