    [0001] -03 049/1 BINDER BASED ON SOLID MINERAL COMPOUND RICH IN ALKALINE-EARTH OXIDE WITH PHOSPHATE ACTIVATORS. The present invention relates to a hydraulic binder rich in calcium oxide and / or magnesium oxide, activated by at least one phosphate-type compound, as well as to building materials obtained from such binders. With the aim of reducing the quantities of CO2 released into the atmosphere, we are now seeking more and more to replace some or all of the Portland cement used in the manufacture of concrete or mortar by other hydraulic binders considered as less polluting. Thus, hydraulic binders are known in which some or all of the Portland cement is substituted by waste from the steel or coal industry such as blast furnace slags or fly ash.
    [0002] Unlike Portland cement, these compounds are not hydraulic in nature and it is necessary to add an activator to dissolve them and make them reactive. It is known to use alkaline agents in large amounts, or with high alkalinity, which has the disadvantage of causing large increases in pH which make the handling of such binders difficult and may cause severe irritation. The solution proposed in the application WO 2011/055063 consists of a softer alkaline activation since very small amounts of bases are required to activate the system comprising particles of finely ground slags. However, this solution is not suitable if the slag is not sufficiently fine and is not totally amorphous. Other systems propose to use a combination of several alkaline activators. For example, EP 2 297 061 which uses as an activator an alkali metal compound and a zinc salt for a binder system containing foundry sand. The present invention provides a binder comprising at least 70% by weight of a mineral solid compound consisting of at least one mixture of silica, alumina and alkaline earth oxides, the total sum of CaO and MgO representing at least 10% by weight of the inorganic solid compound and an activation system comprising at least one phosphate-based compound. The activation system used in the present invention makes it possible to react inorganic solid compounds such as, for example, slags or fly ash irrespective of their crystallinity. Thus, such a system makes it possible to activate amorphous but also partially crystallized slags with particle sizes of up to 5MM. The term "activation system" within the meaning of the present invention, comprises a system comprising one or more compounds intended to improve and / or accelerate the setting and / or hardening of the binder, in particular by facilitating the dissolution of its components. . The binders according to the present invention advantageously have a compressive strength compatible with the desired applications and in particular can be equivalent to that obtained with conventional Portland cement. They furthermore have the advantage of being compatible with the regulations in force concerning the Environment, Health and Safety standards since, unlike slag-based binders or fly ash activated with strong bases such as sodium hydroxide, which lead to high values. higher pH values. The activation system used according to the present invention comprises at least 30% by weight of a compound which is a salt derived from phosphoric acid, the weight percentage being given relative to the total weight of the activation system. This salt is selected from alkali metal polyphosphates such as sodium, potassium or lithium and mixtures thereof. Preferably, the activator is an alkali metal diphosphate or triphosphate. Even more preferentially, the activator is sodium triphosphate of formula Na5P3010. These salts derived from phosphoric acid advantageously make it possible to improve the mechanical strengths of the binders according to the present invention, as compared with known activation systems such as alkaline activation carried out with a mixture of sodium hydroxide and silicate or such a mild activation as described in the application WO 2011/055063. For some applications, it is necessary to have good resistance very quickly at young ages, that is to say from the application of the mortar or concrete composition obtained from the binder. The activation system is further enhanced when it includes other components, in addition to the salt derived from phosphoric acid. The activation system can therefore also include, in addition to the salt derived from phosphoric acid, any constituent known as activator for slags. Mention may be made, for example, of silicates, carbonates and sulphates of metals, of alkali metals and / or of alkaline earth metals.
    [0003] Advantageously, the activation system thus comprises, in addition to the salt derived from phosphoric acid, an alkali metal silicate selected from potassium, lithium and sodium and mixtures thereof. When the silicate is present, its content by weight represents between 5 and 70% by weight relative to the total weight of the activation system.
    [0004] In order to further improve the resistance to young ages, it is also possible to add to the activation system a source of alkaline earth metal and in particular a source of calcium or magnesium. This compound may be chosen from lime, calcium carbonate, portland cement, calcium aluminate cement, calcium sulfoaluminate cement, dolomite and magnesium hydroxide, and mixtures thereof. Lime is particularly preferred. The source of alkaline earth metal, when present, represents between 5 and 70% by weight relative to the total weight of the activation system. On the other hand, to control the reactivity and exothermicity of salts derived from phosphoric acid, the activation system may also comprise a setting retarding agent which is a salt of formula X ± A- in which the X + cation is selected from alkali metals, alkaline earth metals, aluminum and ammonium ion, and the anion A- is selected from acetate, citrate, formate, benzoate, tartrate, oleate, bromide or iodide anions. Preferably, the anion of the retarding agent is an acetate and the cation is chosen from lithium, sodium, potassium, magnesium or calcium. The amount of retarding agent may represent between 0.1 and 10% by weight of the activation system. For certain applications, it is indeed desirable to be able to increase the workability time of the systems. The presence of a retarding agent chosen from the compounds mentioned above makes it possible in particular to modify the rheology of the binder. In one embodiment, the binder according to the present invention comprises an activation system which consists of a mixture of a salt derived from phosphoric acid and an alkali metal silicate. In another embodiment, the binder according to the present invention comprises an activation system which consists of a mixture of a salt derived from phosphoric acid and an alkaline earth metal source. In another embodiment, the binder according to the present invention comprises an activation system which consists of a mixture of a salt derived from phosphoric acid, an alkali metal silicate and a source of phosphoric acid. an alkaline earth metal. Preferentially, the activation system consists of a salt derived from phosphoric acid, an alkali metal silicate and a calcium source.
    [0005] The activation system is added to the binder according to the present invention in an amount ranging between 3 and 30% by weight, preferably between 5 and 25% by weight, relative to the total weight of binder. The binder according to the present invention is essentially based on a mineral solid compound consisting of at least one mixture of silica, alumina and alkaline earth oxides, the total sum of CaO and MgO representing at least 10% by weight. weight of the inorganic solid compound. Preferably, the sum total of CaO and MgO represents at least 20% of the weight of the solid mineral compound. Preferably, said solid mineral compound is a slag, amorphous or crystallized, fly ash and! or glass powders. Slags can be steelmaking slags or blast furnace slags. The fly ash is preferably class C fly ash. The binder according to the invention may also comprise other types of binders, such as, for example, Portland cement, aluminous cement, sulphoaluminous cement, belitic cement, pozzolanic mixture optionally comprising fly ash, silica fumes, calcined shale, natural or calcined pozzolans, a source of calcium sulphate, such as plaster or hemihydrate, gypsum and / or anhydrite. When present, these binders represent less than 27% by weight relative to the total weight of binder. The binder according to the invention is advantageously used in combination with fillers, fillers, sand such as quartz, limestone, wollastonite, metakaolin, crushed glass, rockwool, glass wool or dolomite, or sands and aggregates from concrete deconstruction. It can also be used with low density fillers such as expanded clay, expanded perlite, aerogels, vermiculite, expanded polystyrene, expanded glass aggregates, aggregates from used tire recycling.
    [0006] Other additives conferring particular properties may also be added and enter into the binder composition. The content of each of the additives represents less than 1% by weight of the binder. For example, rheological agents, water-retaining agents, air-entraining agents, thickening agents, foaming agents, microorganism and / or bacterial growth protection agents, dispersing agents may be mentioned. , pigments, retarders, accelerators, as well as other agents to improve the setting, the hardening, the stability of the products after application and in particular to adjust the color, the workability, the implementation or the impermeability.
    [0007] The binder according to the present invention may also comprise adjuvants such as plasticizers, for example products based on polycarboxylic acids and preferably polycarboxylic ethers, lignosulphonates, polynaphthalenesulfonates, superplasticizers based on melamines, polyacrylates. and / or vinyl copolymers, typically in contents of less than or equal to 10% by total weight of binder. It may also include polymers such as cellulose ethers. Similarly, it may comprise adjuvants such as polymers in liquid form and / or in the form of redispersible powder, typically in contents of less than or equal to 10% by total weight of binder. Likewise, it may comprise anti-foaming agents or surfactants, hydrophobic agents, surfactants or surfactants and / or corrosion inhibitors, typically in contents for each of these agents less than or equal to 1% by weight. total binder.
    [0008] The present invention also relates to a concrete composition or a mortar, comprising at least one hydraulic binder as described above. Such a composition is obtained by mixing the binder described above with aggregates, sands and / or aggregates in the presence of water. The aggregates or sands added to the binder depend in particular on the nature of the material that it is desired to obtain. It is most often gravel, sand, dolomite and / or limestone of different granulometries. Another subject of the invention relates to the products of construction obtained after hydration and hardening of said mortar composition. These construction products may be pre-manufactured elements, bricks, plates, blocks, coatings comprising at least one hydraulic binder as described above. These materials have a very satisfactory hardening and mechanical strength. The activation system contained in the binder makes it possible in particular to improve the curing in the short term.
    [0009] The binders according to the invention can be incorporated into all types of pre-mixed mortar such as, for example, adhesive mortars, jointing mortars, tile joints, adhesives. They can also be used to make mortars or concretes for floor (screed and floor plaster), or for interior or exterior wall mortars or wall plasters, or mineral paints such as leveling mortars, sub-plaster monolayers, waterproofing mortars, as well as any type of interior or exterior coating. The following examples illustrate the invention without limiting its scope.
    [0010] Examples Various standard mortar formulations have been prepared. These formulations comprise 1350 g of standardized sand, 450 g of binder, and an activation system. Different binders and activation systems have been tested. The results obtained are presented in the form of a curve, giving the compressive strength in MPa of the samples obtained as a function of time, expressed in days. The amount of activator is indicated in your legends and corresponds to the amount, by weight percent, which is added to blast furnace slags and / or fly ash. The amount of water introduced to prepare the mortar is 225g, which corresponds to a water / binder ratio of 0.5. For each of the formulations, specimens of 4x4x16 cm3 are manufactured according to the protocol below: - Premixing of the slag powders and / or fly ash and pulverulent components constituting the activation system with the sand for 1 min at speed low (600rpm) - adding water and mixing at low speed (-600rpm) for 30sec then mixing at high speed (-1500rpm) for 2mi n3Os - pouring the resulting mortar into a mold and - after hardening, unmolded and measuring the mechanical strength (3-point bending then compression), according to standard NF EN 196-1 (August 1995).
    [0011] Measurements of compressive strengths are made for all samples at different times during the hardening phase to follow the evolution as a function of time. By way of comparison, identical measurements were made on formulations comprising: - 100% Portland cement CEM I 52.5 (which comprises 95% clinker) - 100% CEM III 32.5 cement which is a cement of mixture consisting of 70% blast furnace slag and 30% clinker, - 100% quasi-amorphous blast furnace slag (Ecocem) or 100% class C fly ash with activation type activation system alkaline consisting of a mixture of sodium hydroxide NaOH (VVVR) and sodium silicate Na2SO3 (Metso 510 PQ corporation), pre-dissolved in water to ensure the complete dissolution of this mixture and therefore its total effectiveness as activator. 100% of an activated Ecocem slag by a mild activation system as described in patent application WO 2011/055063 and comprising slag microparticles and a small amount of base (composition described in Table 1 of the present invention). 'example). Different slags or fly ash were tested in the examples below. Their respective composition and the level of amorphous compounds contained in each of the products are given in the table below. Note that the Carmeuse slag is a highly crystallized slag.

The binder 1.5 corresponds to the comparative. Binder 1.1: 93% weight of slag Ecocem and 7% weight of NaTPP Binder 1.2: 90% weight of slag Ecocem and 10% weight of NaTPP Binder 1.3: 88% weight of slag Ecocem and 12% weight of NaTPP Binder 1.4: 75% weight of slag Ecocem and 25% weight of NaTPP Binder 1.5 comparative: 78% weight of slag Ecocem, 11% by weight of NaOH and 11% by weight of Na2SO3, sodium hydroxide and sodium silicate being dissolved beforehand in water before be mixed with the slag with a water / binder ratio = 0.5. Figure 1 shows the evolution of the compressive strength as a function of time for these different binders.
    [0013] All binders according to the present invention exhibit significantly improved strength after 7 to 14 days, compared to the performance achieved with an alkaline activation system. It is thus possible to obtain resistances greater than 40 MPa after 28 days. Example 2 Two binder formulations according to the invention comprising Carmeuse slag, thus highly crystallized and known to be difficult to activate, were prepared as described above, by varying the amount of sodium tripolyphosphate (NaTPP, VWR) used as an activator. The binder 2.3 corresponds to the comparative.
    [0014] Binder 2.1: 75% by weight of Carmeuse slag and 25% by weight of NaTPP Binder 2.2: 88% by weight of Carmeuse slag and 12% by weight of NaTPP Binder 2.3 comparative: 78% by weight of Carmeuse slag, 11% by weight of NaOH and 11% by weight Na2SO3, the sodium hydroxide and sodium silicate being dissolved beforehand in water before being mixed with the slag with a water / binder ratio = 0.5. Figure 2 shows the evolution of the compressive strength as a function of time for these different binders. The binder 2.3 comprising the Carmeuse slag and the conventional alkaline activation system does not take at short times and no resistance is observed before 7 days. The binder according to the invention makes it possible to improve the resistance from an early age (more than 6 MPa at 3 days for a binder comprising 25% by weight of sodium tripolyphosphate).
    [0015] Example 3 A binder formulation according to the present invention with another type of slag was prepared.
    [0016] Binder 3.1: 88% by weight of slag Ment and 12% by weight of NaTPP Binder 3.2 comparative: 78% by weight of Merit slag, 11% by weight of NaOH and 11% by weight of Na 2 SO 3, sodium hydroxide and sodium silicate being dissolved beforehand before being mixed with the slag with a water / binder ratio = 0.5.
    [0017] Figure 3 shows the evolution of the compressive strength as a function of time for these different binders. The binder according to the present invention has improved strengths over those obtained with an alkaline activation system. Example 4 Two Class C fly ash binder formulations according to the present invention were prepared.
    [0018] Binder 4.1: 75% weight of fly ash class This 25% weight of NaTPP Binder 4.2: 88% weight of fly ash class This 12% weight of NaTPP Binder 4.3 comparative: 78% weight of Merit slag, 11% weight of NaOH and 11% by weight of Na 2 SO 3, the sodium hydroxide and sodium silicate being dissolved beforehand in water before being mixed with the slag with a water / binder ratio = 0.5. Figure 4 shows the evolution of the compressive strength as a function of time for these different binders. The binders according to the present invention still have significantly improved strengths over those obtained with an alkaline activation system. Example 5 Two binder formulations according to the present invention were prepared with different activation systems. Binder 5.1: 86% by weight of Ecocem slag, 10% by weight of NaTPP and 4% by weight of sodium silicate (Mets ° 510, PQ corporation) Binder 5.2: 84% by weight of Ecocem slag, 10% by weight of NaTPP, 4% by weight of sodium silicate and 2% by weight of lime (VVVR). These binders are compared with a CEM I 52.5 binder (Comparative Binder 5.3) and a CEM III 32.5 binder containing at least 70% blast furnace slag (Comparative Binder 5.4). Figure 5 shows the evolution of the compressive strength as a function of time for these different binders.
    [0019] The compressive strengths obtained with the binders according to the present invention are quite comparable to those obtained with a CEM I type binder and are higher after 7 days for the binder 5.2.
    [0020] Example 6 Two binder formulations according to the present invention were prepared and compared to a binder formulation in which the activation system is of the "soft alkaline" type as described in WO2011 / 055063.
    [0021] Binder 6.1: 84% by weight of Ecocem slag, 10% by weight of NaTPP, 4% by weight of sodium silicate and 2% by weight of lime (VVVR). Binder 6.2: 89% by weight of Ecocem slag, 4.5% NaTPP, 4.5% by weight of sodium silicate and 2% by weight of lime. Comparative Binder 6.3: 80% by weight of Ecocem slag and 20% by weight of a mixture of activators which notably includes slag microparticles, as described in WO 2011/055063. FIG. 6 represents the evolution of the resistance in compression as a function of time for these different binders.
    [0022] The compressive strengths of the binders according to the present invention are significantly improved with respect to a binder for which the activation is obtained with microparticles of slags, in the presence of a small amount of base. It is also noted, by comparing the strengths of the binders 6.1, 6.2 and 6.3 that the activation system comprising lime improves the mechanical properties at a young age. Comparing the strengths of the binders 6.2 and 6.3, it is noted that, even at a reduced level of activator, the mechanical properties remain higher than the mild activation system which includes a mixture of activators including microparticles slag.
    [0023] Example 7 The following formulations were prepared: Binder 6.1: 84% by weight of Ecocem slag, 10% by weight of NaTPP, 4% by weight of sodium silicate and 2% by weight of lime (VVVR).
    [0024] Binder 7.1: 83% by weight of Ecocem slag, 10% by weight of NaTPP, 4% by weight of sodium silicate, 2% by weight of lime (VVVR) and 1% of potassium acetate. Binder 7.2: 82% by weight of Ecocem slag, 10% by weight of NaTPP, 4% by weight of sodium silicate, 2% by weight of lime (VVVR) and 2% of potassium acetate. Tapping time tests are performed from the insertion of a Vicat needle in the mortar according to standard NF EN 196-3. The measurement of the evolution of the sink rate is characteristic of the evolution of hardening and setting of the material. Figure 7 shows the rate of insertion of the Vicat needle as a function of time. The different curves shown in this figure show that the addition of potassium acetate delays the setting of the binder. The more delaying agent is added, the greater the setting delay. Spreading tests consisting in spreading the mortar under its own weight after lifting a metal cone containing the mortar were carried out in accordance with EN1015-3 which describes the determination of the consistency of a fresh paste of mortar with a shaking table. The results obtained are shown in Figure 8 which shows that the addition of potassium acetate increases the spreading of the mortar, especially since the amount of retarding agent is important in the formulation. 25 30
