Definitions
- the present invention relates to the technical field of composite materials intended for construction, in the general sense, and it relates more specifically, materials with a hydraulic mineral matrix, of the cement, lime or plaster type, inside which lightening charges are incorporated.
- the invention also relates to techniques for developing these new materials.
- the invention finds a particularly advantageous application for constituting a building or facing material in the form of panels or plates or a mixture to be sprayed.
- the object of the invention therefore aims to remedy the drawbacks stated above by proposing a lightweight microcellular composite material produced from a hydraulic binder, offering acoustic soundproofing properties in the audible spectrum and having a low density, as well as a high specific resistance.
- the composite material according to the invention also contains:
- Fig. 1 illustrates the variation curves of the mechanical loss factor ⁇ as a function of the frequency f for two types of materials.
- Fig. 2 is a variation curve of the force F applied to a test piece as a function of its shortening ⁇ l.
- the hydraulic binder used as a constituent for the composite material according to the invention, relates to those commonly used in the construction industry and known to those skilled in the art.
- the hydraulic binder is formed by:
- the material according to the invention comprises, as lightening fillers, hollow microspheres of organic or mineral nature.
- the mineral fillers are white spherical elements based on glass, in particular borosilicate glass with a high proportion of silica.
- These mineral microspheres the thickness of which varies approximately between 0.5 and 3 ⁇ m, have an average diameter of between 30 and 100 ⁇ m for relative specific densities of between 0.12 and 0.6 g / cm 3 .
- the specific surface that is to say the ratio of the developed surface to the volume, is between 0.7 and 1.5 m 2 / g approximately, depending on the density.
- Microspheres have resistance O 95/26323 PC17FR95 / 00385
- the hollow microspheres can also consist of organic fillers in the form of white microstructures, with an average diameter between 20 and 60 ⁇ m and an average wall thickness of the order of 0.1 ⁇ m. Their relative specific density is between 0.03 and 0.07 g / cm 3 .
- the microspheres can be obtained from a thermoplastic of the copolymer (acrylonitrile, vinylidene chloride) or copolymer (acrylonitrile, methacrylonitrile) type.
- the main properties of the hollow microspheres are listed in the attached Table 1. It should be noted that the microspheres used have a total water tightness and a white color making it possible not to harm the aesthetic effect of the material produced.
- the composite material according to the invention also comprises a polymer in a proportion of 3 to 15% by volume and, preferably, from 5 to 8% by volume.
- the polymer is a compound belonging to the acrylic and vinyl groups, such as:
- EVA Ethyl vinyl acetate
- polyvinyl acetates such as the homopolymer in aqueous dispersion sold under the name RHODOPAS A 016 p by the company RHONE-POULENC, - poly (acrylamides),

- MPMC Hydroxypropylmethylcellulose
- the polymer can also be produced from synthetic latex in aqueous dispersion of the type:
- Fig. 1 makes it possible to highlight this function by showing, for a given reference temperature, the phenomenon of mechanical relaxation characterized by the loss factor ⁇ , observed as a function of the excitation frequency, for an uncharged hydraulic mineral matrix (curve A) and loaded with microspheres (curve B). As shown more precisely in fig.
- the insertion into the hydraulic matrix of microspheres of high specific surface, to which is added a small volume fraction of polymer, advantageously between 5 and 8% by volume of dry extracts of thermoplastic material, makes it possible to obtain, at a given reference temperature, a frequency shift of the main mechanical relaxation peak which characterizes the vibratory damping capacity of the solid considered.
- the material also comprises natural or synthetic pozzolans in a proportion of 5 to 50% by weight of cement making it possible to avoid, in over time, surface corrosion of the microspheres resulting from an attack by the lime released during the hydration of the cement.
- the pozzolans which are components known to those skilled in the art, can be of natural origin coming, for example from volcanic ash (pozzolans from Salone in Italy), from high purity clay soils based on montmorillonite (Fuller's earth) .
- Pozzolans can also be synthetic and made from: - fly ash (Cf. Patent n ° 2 149 998),
- compositions, the pozzolanic properties and the methods of selection of these metakaolins are described, in particular, in patents No. 2,575,744, 2,601,356 and 2,634,558.
- very reactive synthetic pozzolans of the metakaolin type will be used in accordance with the criteria defined in the previously cited patents.
- the hydraulic binder is of the fatty lime type
- constituents known to those skilled in the art can be added, such as organic or mineral pigments (decorative applications for example), sands of all kinds, adjuvants capable to improve the viscosity of the elaborate pasty mixtures (fluidizers, water-reducing plasticizers, anti-foaming agents), accelerating or delay-setting adjuvants, or fibrous reinforcements.
- organic or mineral pigments decorative applications for example
- sands of all kinds adjuvants capable to improve the viscosity of the elaborate pasty mixtures (fluidizers, water-reducing plasticizers, anti-foaming agents), accelerating or delay-setting adjuvants, or fibrous reinforcements.
- fibrous reinforcements of an inorganic nature carbon or glass of type E, R or alkali-resistant AR.
- the composition of these alkali-resistant glasses appears in particular in document FR 2 601 356.
- the fibrous reinforcements of an organic nature can be polyester, polyamide, polyethylene, polypropylene, acrylic
- the composite according to the invention may also include metal reinforcements (standard or stainless steel, cast iron) but their advantage is limited due to their high density.
- Reading Tables 2 and 3 which give examples of compositions, will allow a better understanding of the invention.
- Table No. 2 thus shows the composition of different Portland cement mortars numbered from 1 to 9 and three light plaster compositions numbered from 10 to 12. The conditions for curing the samples of light mortar are as follows:
- the lightened plaster samples are kept for 24 hours in a closed mold at 20 ° C, then kept at 20 ° C and 50% Relative Humidity until testing.
- microspheres are for their part, expressed as a percentage of total volume of wet mortar and the glass reinforcements in percentage by weight of wet mortar.
- the mechanical loss factor ⁇ is measured in tension-compression at variable frequency on prismatic samples excited outside the resonance and for a reference temperature of 20 ° C.
- the compressive strength tests are carried out on cylinders with a height / diameter ratio equal to 2.
- the bending measurements correspond to standardized tests in 4-point bending, on plates 10 mm thick.
- the mortars tested were immersed in water at 50 ° C, after 28 days' curing (mechanical control at 40 and 80 days of immersion).
- the speed of sound C L corresponds to a longitudinal wave speed determined at 50 KHz.
- the plasticizer used is of the naphthalene sulfonate or melamine sulfonate type. Examination of table 3 shows that the light cement mortar no 2 and containing no polymer has a low loss factor ⁇ at acoustic frequencies comparable to a dense mortar, ie ⁇ equivalent to 0.4%. In the cement mortar treated this time with an aqueous dispersion of polymer, the incorporation of the microspheres with respect to the same non-lightened mortar (n ° 1) makes it possible to act significantly on the loss factor ⁇ . Between samples 1 and 3, the value of ⁇ is multiplied by a factor greater than 4.
- samples no. 3, 4, 5 and 6 see their loss factor ⁇ vary with the concentration of the polymer and according to its nature. Depending on the frequency band targeted, the choice of polymer, the proportion and the characteristics of the microspheres used therefore influence the loss coefficient ⁇ .
- sample n ° 7 of mortar lightened by an organic load shows, with respect to sample n ° 3 of the same density and the same stoichiometry, a frequency behavior different from the loss factor, more attractive at high frequency.
- the compressive strength is significantly affected by the nature of the microspheres used.
- the compressive strength ⁇ RC reaches 40 MPa in cement mortar no. 8 comprising denser mineral charges and therefore more resistant.
- the organic fillers give mortar no. 7 a compressive strength ⁇ RC of 20 MPa.
- this same resistance reaches 31 MPa (mortar n ° 3) with mineral microspheres of density lower than that tested on mortar n ° 8.
- ⁇ RC increasing with the concentration until reaching values of 2% (mortar n ° 4).
- fig. 2 shows a recording of the rupture in compression of a test piece corresponding to mortar no. 3.
- ⁇ RC Unlike a dense mortar, there still remains beyond the maximum stress ⁇ RC , a capacity for residual deformation and absorption of a certain amount of potential energy.
- the field of elastic deformation is very high: ⁇ EC is close to 1, 0%, and the report elastic limit ⁇ EC on breaking limit ⁇ RC reaches 60%.
- the tests show that the ⁇ EC / ⁇ RC ratio is approximately between 55% (mortar no 4) and 80% (mortar no 2).
- the failure behavior of the composite is further improved compared to mortar no. 3.
- the fall in force beyond the rupture ⁇ RC is slower than with glass microspheres.
- the deformation at break ⁇ RC also increases with the polymer content, from 1 to 1.3% approximately, respectively without and with 8% by volume of styrene-acrylic latex.
- the ratio ⁇ EC / ⁇ RC is always close to 80%, in the case of organic microspheres, for mortar densities close to 1.1 g / cm 3 .
- the elastic deformation finally, varies between 65 and 70% of the deformation at break.
- microcellular acoustic composites with a hydraulic matrix therefore bring, in terms of mechanical performance, significant improvements with respect to conventional light products.
- the durability of the microspheres analyzed in water immersion at 50 ° C is good on the mortars tested # 2, 3, 7, 8 and 9, for the metakaolin level selected (ie 30% by weight of cement).
- Tables 2 and 3 show the properties obtained from three examples of non-limiting compositions.
- plaster n ° 10 the longitudinal velocity reached at 50 KHz, for a density of 0.65 g / cm 3 (with 40% volume of microspheres) is 800 m / s.
- the strain at break ⁇ RC reaches here: 1%.
- the flexural strength exceeds 10 MPa at break.
- the material according to the invention has the advantage of good fire behavior (classification M,), as well as a satisfactory freeze-thaw resistance and easy dry machinability, in particular.
- the composite offers: - a weak hydration shrinkage in the case of cements (mortar n ° 5): ⁇ 7.10 "4 to 28 days of ripening,
- the material according to the invention makes it possible to constitute a compact microcellular composite, waterproof and airtight.
- Another advantage of the invention relates to the possibility of producing the mixtures and the use of the material according to the invention by means of conventional equipment used for cements or plasters, in particular loaded with reinforcing fibers.
- the process for preparing the composite according to the invention consists in: a) producing a light mixture from the following constituents:. about 35 to 55 parts by weight of water mixed with about 3 to 12 parts by total volume of polymer,. from 0 to 5 parts by weight of adjuvant, plasticizer or plasticizer, water reducer, b) incorporate into the mixture from 10 to 65% by total volume of hollow microspheres having a particle size between 10 and 100 ⁇ and a specific density of 0.03 to 0.6 g / cm 3 , c) and to use approximately 100 parts by weight of hydraulic binder.
- hydraulic binder can be used either before step a) or after step b).
- a process for manufacturing a composite is described below:
- water additive of the polymer in a proportion of 35 to 55 parts by weight for water and 3 to 15 parts in total volume of polymer, the microspheres of borosilicate glass or of polyacrylonitrile-vynilidene chloride, in a proportion included between 10 and 65% approximately, advantageously between 20 and 45% of the total volume,.
- the water-reducing fluidizer if any, in a proportion of 0 to 5 parts by weight; the light mixture thus formed is kneaded, preferably at low speed, until a homogeneous paste is obtained, and repeat the operations in the order described above in the case of a plaster type binder without using synthetic pozzolans, or water-reducing fluidizer.
- the final mixing takes place at low speed.
- reinforcing fibers such as E glass fibers for plasters and E, R or AR glass fibers for lime or cement and in proportions of between 2 and 15% by weight, advantageously between
- the doughs obtained can be molded by gravity casting in complex shapes or in thin plates with a thickness of 5 mm for example, without any variation in their density. A vibration of the molds can complete the setting in place of the pasty mixture.
- microspheres used give the mixture obtained a thyxotropic nature, in particular for volume fractions greater than
- microcellular, light and sound absorbing composite material according to the invention makes it possible to constitute a building or facing material.
