Abstract
A novel cement composition for 3D printing including has 90% to 99.5% by weight of one or more cements selected from a Portland cement, an aluminous cement, a sulphoaluminous cement and a prompt natural cement; and has 0.5% to 10% by weight of a silicoaluminous filler having a specific surface area of at least 5 m2/g, as well as a method for implementing the composition.
Claims10
A cement composition comprising:
- from 95% to 99.5% by weight of a Portland cement and a sulphoaluminous cement;
- and
- from 0.5% to 5% by weight of a filler selected from the group consisting of a silicoaluminous filler, silica fume, and a combination of a silicoaluminous filler and silica fume, wherein the filler has a specific surface area of at least 5 m2/g,
- wherein the cement composition is adapted for 3D printing,
