- equivalent diameter of the particles is more particularly between 1 and 150 ⁇ m.
- equivalent diameter is meant the longest dimension of the cross section of the anisotropic particle; this dimension making it possible to define a circle in which the shape of this cross section can be introduced.
- the cross section corresponds to the section crossing substantially perpendicularly, the plane of largest surface of the particle.
- the cross section of the anisotropic particle can be circular, but also ellipsoidal, multilobed, parallelepipedic or even polyhedral.
- the geometry of the cross section depends for example on the die used in the case of shaping by spinning of said anisotropic particles.
- the anisotropic particles are in the form of fiber or ribbon.

- the filler content represents at most the same weight as the hydraulic binder.
- Another object of the invention consists of a cement paste comprising the cement described above and water.
- the water used can come from various sources. Thus, it is possible to use the water present on the drilling or construction site (so-called formation water) insofar as the content of compounds which it contains, such as essentially salts, does not interact with contrary to the other constituents of cement, cement paste or consolidated material.
- the water content it can be easily determined by a person skilled in the art. It depends inter alia on the desired characteristics of rheology and density of the cementitious paste.
- the present invention likewise relates to the preparation of cement paste. According to a first method, the cement is brought into contact with water.
- the cementitious paste is obtained by bringing the hydraulic binder, possibly the filler and optionally the additive, into contact with water, then the anisotropic particles are added.
- the particles can be introduced in dry form, that is to say, depending on the nature of the polymer, in the presence or not of associated water, or else in the form of a dispersion, more particularly aqueous . If the particles are incorporated in the form of a dispersion, the water content added before the incorporation of the particle suspension takes account of the water content in said suspension.
