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.
Claims16
A hydraulic composition comprising 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 comprised between 10 and 25 μm;
- from 25 to 76 parts of a second Portland cement the particles of which have a D50 comprised between 0.5 and 6 μm;
- from 85 to 200 parts of sand;
- water;
- O the water content being such that the hydraulic composition comprises 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,
- and wherein the hydraulic composition is self-leveling.
A hydraulic binder 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 comprised between 10 and 25 μm;
- from 25 to 76 parts of a second Portland cement the particles of which have a D50 comprised between 0.5 and 6 μm;
- from 85 to 200 parts of sand;
- 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, and
- wherein the hydraulic binder does not comprise liquid admixtures,
- wherein upon being combined with water, to form a hydraulic composition, in an amount ranging from 170 to 250 kg of water per cubic metre of hydraulic composition, the hydraulic composition is self-leveling.
