Definitions
- the present invention concerns the field of compositions with hydraulic binder bases, containing at least one mineral matter which is a calcium carbonate obtained by dry grinding.
- This grinding which leads to a reduction in the size of the individual particles of calcium carbonate by mechanical action, is assisted by grinding agents which can be classified into the following 3 categories.
- the first comprises the weak acids (formic, acetic, lactic, adipic as mentioned in document FR 2 863 914, or stearic as indicated in document EP 0 510 890), and their salts (sodium lignin sulfonate, sodium acetate, etc.).
- the second includes the weak bases, and notably the amines (see document GB 2 179 268).
- the third and the most commonly used, since it is the most effective, includes the glycol-based alcohols, including notably diethylene glycol illustrated in documents WO 2002/081 573 and US 2003/019 399.
- a first object of the invention consists in the use, in a composition with a hydraulic binder base, of a calcium carbonate characterised in that the said carbonate is dry-ground in the presence of a grinding aid agent, firstly, and in that the grinding aid agent is, secondly, a copolymer, consisting:
- This grinding aid agent may be designated using the expression of a copolymer of methacrylic acid with a monomer containing an alcoxy or hydroxy polyalkyleneglycol group.
- a calcium carbonate according to the invention enables a composition to be obtained with a hydraulic binder base such as a mortar with a much higher degree of spreading.
- the said copolymer is obtained in the acidic form and possibly distilled, and is possibly partially or totally neutralised by one or more neutralisation agents having a monovalent or polyvalent cation, where the said agents are chosen preferentially from among ammonia or from among calcium, magnesium hydroxides and/or oxides, or from among sodium, potassium or lithium hydroxides, or from among the aliphatic and/or cyclic primary, secondary or tertiary amines, such as preferentially stearylamine, the ethanolamines (mono-, di- and triethanolamine), mono- and diethylamine, cyclohexylamine, methylcyclohexylamine, amino methyl propanol, morpholine, and preferentially in that the neutralisation agent is chosen from among triethanolamine and sodium hydroxide.
- the neutralisation agent is chosen from among triethanolamine and sodium hydroxide.
- copolymer is obtained by processes of radical polymerisation in solution, in a direct or reverse emulsion, in suspension or precipitation in solvents, in the presence of catalytic systems and chain transfer agents, or again by processes of controlled radical polymerisation, and preferentially by nitroxide mediated polymerisation (NMP) or by cobaloximes, by atom transfer radical polymerisation (ATRP), by controlled radical polymerisation by sulphurated derivatives, chosen from among carbamates, dithioesters or trithiocarbonates (RAFT) or xanthates.
- NMP nitroxide mediated polymerisation
- ATRP atom transfer radical polymerisation
- sulphurated derivatives chosen from among carbamates, dithioesters or trithiocarbonates (RAFT) or xanthates.
- the said copolymer may possibly, before or after the total or partial neutralisation reaction, be treated and separated into several phases, according to static or dynamic processes known to the skilled man in the art, by one or more polar solvents belonging preferentially to the group constituted by water, methanol, ethanol, propanol, isopropanol, the butanols, acetone and tetrahydrofuran or their blends.
- polar solvents belonging preferentially to the group constituted by water, methanol, ethanol, propanol, isopropanol, the butanols, acetone and tetrahydrofuran or their blends.
- One of the phases then corresponds to the polymer used according to the invention.
- This use is also characterised in that 0.05% to 5%, preferentially 0.1% to 3%, and very preferentially 0.1% to 1%, by dry weight of the said copolymer relative to the dry weight of calcium carbonate is used during the dry grinding of the said carbonate.
- composition with a hydraulic binder is a cement, a concrete or a mortar.
- a second purpose of the invention consists of the compositions with a hydraulic binder base obtained by the use of dry-ground calcium carbonate according to the invention.
- This preparation is used to fill an Abrams mini-cone (minimum weight: 4 kg, upper diameter: 50 mm, lower diameter: 100 mm, height: 150 mm).
- the cone is positioned on a PVC plate dampened using a sponge.
- the cone is then raised when it is filled; its contents are spread on the PVC plate. After 30 seconds the spreading is determined by measuring the length in mm of two perpendicular diameters of the round cake obtained, and by taking the average of the two.
- This test illustrates the prior art and uses a calcium carbonate obtained by dry grinding in the presence of 3000 ppm (relative to the dry weight of calcium carbonate) of a grinding agent of the prior art, which is diethylene glycol.
- This test illustrates the prior art and uses a calcium carbonate obtained by dry grinding in the presence of 3000 ppm (relative to the dry weight of calcium carbonate) of a grinding agent of the invention which is a polymer consisting, by weight percentage, 81.5% of methoxy polyethylene glycol methacrylate of molecular weight 2000, 4.9% of methacrylic acid, and 13.6% of acrylic acid.
- a grinding agent of the invention which is a polymer consisting, by weight percentage, 81.5% of methoxy polyethylene glycol methacrylate of molecular weight 2000, 4.9% of methacrylic acid, and 13.6% of acrylic acid.
- This test illustrates the prior art and uses a calcium carbonate obtained by dry grinding in the presence of 1400 ppm (relative to the dry weight of calcium carbonate) of a grinding agent of the prior art, which is diethylene glycol.
- This test illustrates the prior art and uses a calcium carbonate obtained by dry grinding in the presence of 1400 ppm (relative to the dry weight of calcium carbonate) of a grinding agent of the invention which is a polymer consisting, by weight percentage, 81.5% of methoxy polyethylene glycol methacrylate of molecular weight 2000, 4.9% of methacrylic acid, and 13.6% of acrylic acid.
- a grinding agent of the invention which is a polymer consisting, by weight percentage, 81.5% of methoxy polyethylene glycol methacrylate of molecular weight 2000, 4.9% of methacrylic acid, and 13.6% of acrylic acid.
- n o 2 and 4 The polymer used in tests n o 2 and 4 is obtained by polymerisation techniques well known to the skilled man in the art.
- the temperature is then raised and 604.78 g is distilled.
- the temperature is brought down to between 50 and 60° C., and 69.34 g of sodium hydroxide at 50% mass in water is added to the reactive medium.
- the medium is diluted with 20.85 g of water. It is cooled again before obtaining the polymer of the invention.
- compositions of each mortar and the spreading values are given in table 1.
