Definitions
- the present invention relates to a mineral binder based on phosphates.
- This type of binder used in construction products results from an acid-base reaction between a metal oxide and a salt or a phosphoric acid derivative.
- Most basic oxides which react with phosphoric acid or one of its acid derivatives form, when mixed with water, a homogeneous mass which hardens with time at room temperature.
- phosphatic cements mention may be made of phosphomagnesium cements which have been developed to compete with synthetic resins since they make it possible to obtain quick-setting concretes with an almost immediate appearance of the desired resistances. They are particularly applicable in the biomedical field and in dentistry, in the rapid repair of roads, tracks or bridges, or in the encapsulation of hazardous waste.
- a cement of this type called Cerami Crête developed at Bat s-Uni is obtained by mixing magnesium oxide or magnesia, with potassium monophosphate KH 2 PO.
- magnesia reacts with phosphate groups under acidic conditions to form an insoluble phosphate phase which hardens and has the properties of a ceramic.
- This phase is k-struvite of formula MgKPO 4 , 6H 2 0.
- Boric acid is very often used to increase the workability time of this type of cement.
- boric acid is classified as a toxic substance for reproduction. Other solutions for controlling setting time are therefore contemplated.
- Articles describe the possibility of lengthening the setting time and thus the workability by using a particular magnesium oxide, namely calcined magnesia at high temperature and by varying the particle size of the basic metal oxide used. But this does not allow to achieve setting times or workability comparable to those obtained for systems based on Portland cements.
- Another disadvantage of this type of system is related to the strong exothermicity of the reaction that takes place between magnesia and phosphate. Boric acid used as retarder does not control the thermodynamics of the reaction. The end user must therefore take into account this high exothermicity which causes a significant evaporation of the water present in the system during the preparation of the construction material.
- the present invention relates to a phosphate-based inorganic binder obtained by reaction between at least one basic component and an acid phosphate salt, in the presence of a retarding agent which is a salt X + A " whose solubility in aqueous medium measured at 25 ° C is greater than that of the acidic phosphate salt, and in which
- X " is a cation selected from alkali metals, alkaline earth metals, zinc, aluminum and ammonium ion, and A- is an acetate, formate, benzoate, tartrate, oxalate, oleate, bromide or iodide anion.
- the presence of the retarding agent as described above advantageously makes it possible to control the kinetics and the exothermicity of the acid-base reaction that takes place between the basic constituent (s) present and the acidic phosphate salt.
- the use of such a retarding agent makes it possible to avoid the use of boric acid or its derivatives.
- the basic constituent, acting as a base in the acid-base reaction for obtaining the binder according to the invention is chosen from metal oxides, metal hydroxides or sulphates.
- Oxides metal may be calcium oxide, magnesium oxide, zinc oxide, aluminum oxide, and / or iron oxide.
- the metal oxide may also be introduced in the form of a more complex inorganic compound which comprises one or more metal oxides. Mention may be made in this category of silicates, metallurgical slags (for example steelworks slags or blast furnace slags), lime, fly ash, dolomite, mica, kaolin and / or metakaolin.
- Metal hydroxides such as magnesium or calcium hydroxide can also be used as the basic component for forming the binder according to the present invention.
- Sulphates such as calcium sulphate can also be used as the basic component for forming the binder according to the present invention.

- the acidic phosphate salt thus comprises at least one proton capable of being released during the aqueous dissolution of the binder, resulting in an acid attack to dissolve the metal oxide present in solution.
- the acidic phosphate salt is chosen from potassium dihydrogen phosphate KH 2 PO (MKP), ammonium dihydrogen phosphate (NH 4 ) H 2 PO (MAP) and diammonium hydrogen phosphate (NH 4 ) 2 HPO 4.

- calcium dihydrogen phosphate Ca (H 2 PO 4 ) 2 sodium dihydrogen phosphate NaH 2 PO 4, aluminum hydrophosphate AIH 3 (PO) 2 xH 2 O, calcium metaphosphate Ca (HPO 3) 2

- a salt whose cation is identical to the cation of the acid phosphate salt involved in the binder formation reaction will be chosen as a retarding agent.
- the retarding agents whose anions are acetates or formates are preferred. These anions make it possible to obtain a longer workability time and a better control of the exothermicity of the reaction.

That of sodium pyrophosphate Na 4 P 2 O / is about 7 under the same conditions. 3 this additional phosphate compound is a base it is It is important, however, that the amounts introduced into the binder composition remain, however, low in order to maintain the acidic nature of the phosphorus-based component occurring in the acid-base reaction.
