Definitions
- the invention relates to a new hydraulic phosphomagnesium binder and a mortar obtained from this new binder.
- Phosphomagnesium cements are hydraulic binders, that is to say binders which, in the presence of water, solidify. They are characterized by a binder based on phosphorus and magnesium compounds.
- cements are particularly interesting for their rapid setting and their high mechanical properties. This very rapid setting is particularly advantageous in applications such as the repair of structures for which rapid return to service is desired.
- Phosphomagnesium binders like most hydraulic binders, however, exhibit a degradation of their mechanical properties after exposure to high temperatures. This degradation does not allow them to be used in applications such as sealing for chimney flues or fire panels.
- the object of the present invention is to provide a new phosphomagnesium binder which makes it possible to obtain a material which retains its mechanical properties after exposure to high temperatures.
- This object is achieved by the present invention which relates to a phosphomagnesium binder which comprises at least one magnesium compound and a mixture of phosphorus compounds, the mixture of phosphorus compounds comprising at least two compounds chosen from an aluminum phosphate, a phosphate potassium and an ammonium phosphate.
- the invention also relates to a cement matrix which comprises the phosphomagnesium binder of the invention and granular elements.
- the invention also relates to a method for preparing a mortar which comprises adding water to the cementitious matrix and, mixing the matrix added with water to obtain a homogeneous and fluid mortar, the quantity of water added being such that the ratio E / L is between 0.20 and 0.50, E representing the amount of water and L the amount of magnesium compound and phosphorus compound, the mortar thus obtained, and the articles capable of 'be obtained from phosphomagnesium mortar.
- a phosphomagnesium binder comprising a particular mixture of phosphorus compounds makes it possible to obtain articles which have good mechanical properties at room temperature and whose mechanical properties are preserved after exposure to high temperatures.
- the term "mortar” indifferently denotes mortars or grouts based on phosphomagnesium binder.
- phosphorus compound all of the phosphorus-based compounds can be used insofar as they comprise phosphorus pentoxide, available directly or in the form of a precursor.
- ammonium, aluminum and potassium salts of the following phosphorus compounds may be mentioned without intending to be limited, as ammonium phosphate, potassium phosphate and aluminum phosphate: phosphorus pentoxide, phosphoric acid or derivatives such as orthophosphoric acid, pyrophosphoric acid, polyphosphoric acid.
- the phosphomagnesium hydraulic binder can contain these phosphorus compounds alone or as a mixture provided that a mixture as defined above is obtained.
- the mixture of phosphates is a mixture which comprises an ammonium phosphate and at least one phosphorus compound chosen from a potassium phosphate and an aluminum phosphate.
- the phosphate mixture comprises an aluminum phosphate and a potassium phosphate.
- the mixture comprises an aluminum phosphate, an ammonium phosphate and a potassium phosphate.
- the ammonium salt is a phosphate or an ammonium hydrogenphosphates, alone or as a mixture. Even more preferably, the ammonium salt is ammonium dihydrogenophosphate, optionally mixed with ammonium tripolyphosphate.
- the potassium salt is a potassium phosphate.
- the aluminum salt is an aluminum phosphate or metaphosphate, alone or as a mixture. Even more preferably, the aluminum salt is aluminum metaphosphate.
- the amount of each of the phosphorus compounds in the mixture varies depending on the intended application.
- the quantity of ammonium phosphate (s) is predominant compared to the total quantity of phosphorus compounds entering into the composition of the phosphomagnesium binder.
- the phosphorus compounds can be in liquid or solid form, preferably solid.
- the phosphorus compounds are in the form of particles whose particle size is more particularly at most 300 ⁇ m. It should be noted that this value is not critical and that, if it is possible to use constituents whose particle size is greater than 300 ⁇ m, grinding before incorporation into the composition according to the invention may be desirable . This grinding can improve the kinetics of dissolution of phosphorus compounds.
- the phosphorus compounds are used in a form adsorbed on a porous support.
- a porous support mention may be made, for example, of diatomaceous earth, clay, bentonite, silica, alumina.
- the adsorption is carried out in a manner known per se.
- the phosphorus compounds, in solution or in suspension are brought into contact with the support, with stirring, then the resulting suspension is heated so as to evaporate the excess liquid.
- This operation can likewise be carried out by impregnating the support in a drum or on a rotating disc.
- the phosphomagnesium binder also comprises at least one magnesium compound.
- Any magnesium-based compound is suitable for the present invention as long as it reacts with the phosphorus compound in the presence of water.
- the following magnesium compounds magnesium oxide, magnesium hydroxide, magnesium carbonate.

It would be possible to use compounds whose particle size is outside the aforementioned range, but without this bringing any particular advantages. Thus, if the particle size is greater than 500 ⁇ m, a grinding step prior to incorporation into the composition may be necessary. Furthermore, if the particle size of said constituents was less than 10 ⁇ m, one could observe a modification of the properties of the composition brought into contact with water. One can in particular note an increase in the setting speed of the cement, except to increase the content of agent delaying the setting, which will be discussed in the following description. As a result, the mortar according to the invention could be less advantageous from the point of view of implementation or from an economic point of view.

- the amount of water to be introduced for the preparation of the mortar according to the invention is such that a homogeneous and malleable plastic paste is obtained. It depends on the subsequent application of the mortar. Indeed, if one wishes to make internal coatings of piping, the paste is in general more cohesive than a mortar intended to constitute a floor covering, or the preparation of slabs or panels.
