    专利说明:

    [0001] The present invention relates to a method of manufacturing a masonry element, or a masonry block, in particular a building block, composite and insulating and the element, or block, obtained by said method. Bare concrete blocks are widely used building blocks, the material being one of the most economical to buy. Its thermal insulation properties however remain limited. To improve its thermal properties, the concrete blocks can be lightened by lightening the concrete. Furthermore, they can be molded so as to include internal voids so as to benefit from the insulating properties of the air. In this case the cells must be of small dimensions, for example elongated cells whose thickness does not exceed 2 cm. Such blocks, however, are more difficult to manufacture and use a larger amount of raw material. Insulating materials have been placed inside lightweight concrete blocks to improve the thermal resistance of these building blocks, thereby creating composite blocks. Thus it is known to introduce mineral wool, glass wool or polystyrene inside lightweight concrete blocks. The manufacturing process is however uneconomical. More recently it has been proposed to fill the cells with cement foams because cement foams have interesting thermal insulation properties. However, filling cavities in lightweight concrete blocks with cement foams requires quick setting foams such as calcium aluminate cement foams. When slow-setting foams are used and introduced as foam, the foam tends to collapse, destabilize, shrink upon curing and detach from the wall of the cavities. Such a phenomenon is, of course, to the detriment of the thermal properties of such composite blocks. Rapid setting foams, particularly calcium aluminate cement based foams, are economically unattractive and difficult to use in an industrial process because of their rapid setting (fouling phenomenon). The object of the invention is to overcome these disadvantages by providing a method of manufacturing a composite insulating block comprising a mineral foam, said method comprising the following steps: a) arranging a block, preferably a light concrete block or a brick, Comprising at least one cell having walls, said walls being either sufficiently moist or comprising a water-repellent material, and b) filling said cell with a mineral foam comprising substantially no calcium aluminate cement. mineral foam does not substantially comprise quick-setting cement, preferably the walls of the cell (which may be a single wall (e.g. circular example) consist of a water-repellent material.
    [0002] The term "substantially not" refers to a composition that does not include a sufficient amount of compound for its presence to have actual effects on the setting of the foam. Thus the presence of less than about 5% by weight of the dry mixture, or traces of this compound will not affect substantially the setting of the foam and such a quantity can therefore be in the composition without it actually understands this compound. Definitions: Alveolus: a hollow, a void or an excavation present on the surface or inside the block. Very advantageously, the cell present in the block used in the process according to the invention is a "through" cell, that is to say an opening passing through the block from one side to the other. Concrete: a mixture of a cement, with water, possibly aggregates and / or admixtures in accordance with the EN 934-2 standard of September 2002, and possibly additions. The expression "concrete" denotes indistinctly a composition in the fresh or hardened state. The concrete may be a cement slurry, a mortar, a concrete or a lime slurry. Preferably, the concrete is a mortar or a concrete. Lightweight concrete: Light concretes are obtained by playing on the structure (cavernous concretes) or on the use of light aggregates (such as pumice aggregates, expanded shale, expanded clay or polystyrene, or even particles of cork or wood). Adjuvants such as air entrainers may also be added for maximum relief. Empty spaces can also be created by a reaction causing gas evolution: this is the case of cellular concrete or foam concrete. The lightweight concretes blocks according to the invention offer a much lower density than a conventional product, these densities being 300 to 1800 kg / m3, against 2300 kg / m3 for conventional concrete. Cement: A cement is a hydraulic binder comprising a proportion of at least 50% by weight of calcium oxide (CaO) and silicon dioxide (SiO2). These quantities being determined by the EN 196-2 standard of April 2006. The cements that can be used to produce either the mineral foams or the cell blocks can be selected from the cements described in the NF-35 standard. EN197-1 of February 2001, in particular be cements CEM I, CEM II, CEM III, CEM IV, or CEM V. Advantageously the cement mainly comprises Portland cement, such as CEM I.
    [0003] The cements not suitable according to the invention for producing the mineral foam are calcium aluminate cements or their mixtures. The calcium aluminate cements are cements generally comprising a C4A3, CA, C12A7, C3A or CiiA7CaF2 mineralogical phase or mixtures thereof, such as, for example, the Fondu® Cements, the sulphoaluminous cements and the conformal calcium aluminate cements. the European standard NF EN 14647 of December 2006. Such cements are characterized by an alumina content (Al 2 O 3) greater than or equal to 35% by mass. Thus, for carrying out the process according to the invention, the alumina content of the dry mineral compound used to make the foam is less than 35% by weight of the dry mineral compound. Preferably this content is less than or equal to 30%, advantageously less than or equal to 20%, more preferably less than or equal to 15%, and still more preferably less than or equal to 10% by weight of the dry compound. Hydraulic Binder: Material that takes and hardens by hydration. The setting is the transition from liquid or pasty state to solid state. The setting is followed or accompanied by a hardening phenomenon where the material acquires mechanical properties. Hardening usually occurs after the end of setting, especially for cements. Dairy: for example as defined in standard NF EN 197-1 of February 2001, paragraph 5.2.2, or it is a co-product of the metallurgy containing metal oxides, mainly silicates, aluminates and lime. Brick: Brick is a rectangular parallelepiped, raw clay soil, sun-dried or baked, used as a building material. Clay is often mixed with sand. The term "mineral foam" refers to a complex medium mixture comprising a hydraulic binder, especially cement, mixed with gas bubbles, usually air. It is preferred that the air bubbles of this foam have a D50 of less than or equal to 400 μm. The term "sufficiently moist" means a degree of moisture sufficient to prevent the retraction of the foam during its hydration (ie, setting) and drying thereof. This moisture content can generally be that of fresh lightweight concrete blocks at the end of the demoulding. Alternatively, in the case of blocks taken and / or cured, this moisture content can be achieved by the addition of water, especially by soaking or watering, until saturation of the block. The term "water-repellent material" refers to a material that prevents the transfer of a quantity of water adequately. For example, sufficient water repellency is achieved when a drop of water deposited on the surface of the material has a contact angle greater than 90 °. The term "composite" describes the combination of a building block comprising one or more structural voids, preferably through-holes, of which at least one, and preferably all, are filled with a mineral material whose structure or composition is different from that of said block. According to a first embodiment, the block, and in particular its or its cells, is moistened and contains a certain amount of water uncomplexed to other elements before the foam is placed in the cells. This humidification can be carried out by adding water to the block, for example by soaking, watering or spraying. Alternatively the moisture can come from the absence of drying during the manufacture of the block. Indeed, when the block is obtained from the shaping of an aqueous paste (for example based on clay (brick), lime or Portland cement), the foam can advantageously be introduced into the cells. before the block is taken and / or hardened, that is to say in a block whose concrete is in the fresh state. This method of manufacture is very advantageous since it saves time by combining curing and humidification steps as well as avoiding additional steps for manipulating the blocks. Thus, the method according to the invention can advantageously include the use of a block whose concrete is in the fresh state during step b), in particular a fresh lightweight concrete block. For certain types of blocks, such as lightweight concrete blocks, the amount of water contained in just formed blocks (fresh blocks) is particularly suitable for the presence of mineral foam, especially cement-based. Thus, according to one embodiment and a particularly preferred aspect of the invention, the manufacturing method comprises a step of forming the block (for example a molding step) followed either immediately or in a short period of time by a step of filling the cell or cells of the block. It is preferred that this period of time does not exceed 30 minutes and is advantageously less than 10 minutes, for example about 5 minutes. The use of uncured blocks, that is to say fresh formed or in the process of hydration and / or hardening is a particularly innovative aspect of the invention. According to this particularly preferred aspect of the invention, and when the block is made of lightweight concrete, the desired texture of the concrete is wet earth type. It is difficult to characterize the rheology of such a material by a simple test. Only 35 visual and tactile aspects (formation of a ball in the hand that is not totally linked) make it possible initially to evaluate the formulation adequately. The realization of the test makes it possible to verify the quality of the formulation.
    [0004] However, the amount of water to be used is generally from 3 to 15% by weight relative to the dry matter of the dry hydraulic binder / granulate mixture (or premix), preferably from 4 to 10% and even more advantageously from 5 to 10% by weight. , 3 to 6.9%. According to a second embodiment, the outer wall of the cells is in a water repellent material which, in particular by closing pores, does not allow little or no aqueous transfer. It is possible to use water-repellent surface compounds, used as surface coatings, or water-repellent, incorporated in the concrete during the construction of the block. The water repellent compound that can be used, alone or as a mixture, for water-repellent concrete or a block is advantageously chosen from the group consisting of the following compounds: Silicon derivatives such as: polyhydromethyl siloxanes, polydimethylsiloxanes, organosiliconates (such as potassium or sodium methyl siliconate and in general alkylsiliconates), organosilanes (such as octyl trimethoxysilane, octyl trethoxysilane, butyl trimethoxysilane, butyl triethoxysilane and linear or branched C1-C12 alkyl chain alkoxysilanes), organosilanols, alkyltrichlorosilanes and fluorinated silicones. Fluorinated derivatives such as polytrifluoroethylenes, polytetrafluoroethylenes and fluorocarbon derivatives. - The fatty chains alkyl, natural or synthetic, such as linear or branched paraffins, including polyethylenes or polypropylenes. Fatty acid derivatives such as stearates, oleates, palmitates, behenates and Guerbet derivatives (for example calcium stearates or calcium oleate). The water-repellent compound can therefore be used during the mixing of the concrete (in the mass) or in post-treatment on an already formed block, by impregnation or by application with a spray on the surface of the block. The water-repellent compound may be in powder form or in liquid form. The liquid forms may be homogeneous or may be emulsions or dispersions. Some of its compounds, such as organosilanes, are hydrolysed in the presence of cement and water in organosilanols which polymerise and bind covalently with the surfaces of concrete and aggregates to make them hydrophobic. Polyhydromethyl siloxanes are also hydrolyzed and polymerized in situ. Products such as fatty acid salts or polydimethylsiloxanes or paraffins are trapped in the porosity. They prevent the movement of water and make the substrate hydrophobic.
    [0005] A preferred water-repellent compound is CHRYSOFUGE® C, a product of Chryso. CHRYSOFUGE® C is a concentrated calcium-base-based water repellent whose use is recommended for concrete whose hydraulic binder includes lime. With this compound, it forms hydrophobic micelles that obstruct the capillaries of concrete. Thus the method according to the invention may advantageously comprise a step of applying a water-repellent compound to the walls of the cell of the block, for example by dipping or spraying, a preliminary step in the filling step. The method according to the invention may also, or alternatively, include the use of a block comprising a water-repellent compound mixed in its mass. Thus, the method may comprise, when the block is a lightweight concrete block, a step of obtaining a block by mixing a hydraulic binder and granules and at least one water-repellent compound, said step being a preliminary step at the filling stage. The block used in the process according to the invention is preferably a concrete block comprising a cement and aggregates, advantageously of generally parallelepiped shape. When a water-repellent compound is used, the cement may comprise a certain amount of slag, for example from 2 to 33% by weight of the total mass of cement. The aggregates may be aggregates selected from the 0/4, 0/6 and 4 / 6.3 mm aggregate groups or mixtures thereof. According to a particularly preferred aspect of the invention, the concrete block is a lightweight concrete block. The lightweight aggregates of the lightweight concrete block can be pumice, and preferably a pumice sand size 0 / 6mm. According to another aspect of the invention, the block may be formed of an aqueous paste based on clay, such as a brick. The cells are generally cells or recesses of standard size in the manufacture of building blocks. Thus they can generally have dimensions greater than 152 cm3. The mineral foam is preferably a cementitious mineral foam having a density of less than 600 kg / m3. Preferably, the mineral foam has a very low thermal conductivity. Decreasing the thermal conductivity of building materials is highly desirable as it provides heating energy savings in apartment buildings and workplaces. Thermal conductivity (also called lambda (A)) is a physical quantity that characterizes the behavior of materials during heat transfer by conduction. Thermal conductivity is the amount of heat transferred per unit area and a unit of time under a temperature gradient. In the international system of units, the thermal conductivity is expressed in watts per meter Kelvin (VV, m-1, K-1). Conventional or conventional concretes have a thermal conductivity between 1.3 and 2.1 measured at 23 ° C and 50% relative humidity. The mineral foam according to the invention may be chosen from foams having a thermal conductivity ranging from 0.03 to 0.1 W / mK, preferably from 0.03 to 0.06 W / mK and more preferably from 0.03. at 0.046 W / mK An object of the invention is also a composite block, and more particularly a masonry block, obtained by the method according to the invention as well as its use in the field of construction. Another subject of the invention is a composite insulating block comprising a block, said block comprising at least one cell having walls possibly made of a substantially water-repellent material, said cell being filled with a mineral foam not comprising any cement of water. calcium aluminate. Preferably, said foam does not comprise quick setting cement. According to a particularly advantageous aspect of the invention, the cured mineral foam is stable, that is to say that it does not collapse or come off the walls. The block and the mineral foam may be as described above with reference to the method of the invention. Another object of the invention is a composite insulating block as described above or obtained according to the method described above for the construction and more particularly the masonry. The invention will be better understood on reading the examples and accompanying figures, which are not limiting in nature, in which: FIG. 1 shows blocks of concrete filled with a cement foam according to the invention; Figure 2 shows a portion of a concrete block of Figure 1 after drying; and Fig. 3 is a comparative example of a concrete block when the method according to the invention is not practiced.

    [0007] Obtaining the concrete The method of obtaining the concrete in the examples below was carried out according to a standard protocol which is the following: - Introduction of the aggregates into the mixer. - Homogenization during 30s. - Introduction in 30s of the prewetting water (4% of the mass of aggregates). - Mixing for 1 min. - Rest for 4 min (time required to reach the absorption equilibrium 15 aggregates). - Introduction of binders. - Mixing for 1min. - Introduction of mixing water in 30s. - Mixing for 1 min30s. 20 - Sampling. The homogenization and mixing were carried out by a standard mixer whose technical characteristics are as follows: vertical axis mixer with eccentric blades and revolving bowl brand Zylos. For light concrete, the process of obtaining in the example below was carried out according to a standard protocol which is as follows: - Introduction of aggregates and binders in a kneader - Kneading for 1min. 30 - Introduction of the mixing water in 30s. - Mixing for 1 min30s. - Sample. Formation of the Blocks Once the concrete has been obtained, blocks comprising two cells have been made by pouring the concrete into molds and by compaction using vibrating presses (vibro-compaction) according to known and usual methods.
    [0008] To make the blocks (board 4 blocks 15X20X40 cm) the amount of materials used was 15.6 kg to obtain blocks of about 14 kg. Production and implementation of the mineral foam The grout was produced with a Rayneri type mixer. The mixing protocol was as follows. The mineral foam was produced from the mixture of a cement slurry and an aqueous foam, which were homogenized continuously in a static mixer. This mineral foam may be of the same type as those described on pages 23 to 26 of the patent application published under number VV02013 / 150148A1 in the name of the applicant. In summary, a "cement slurry" was obtained by using a solid compound, or premix, comprising one or more hydraulic binders, (for example Portland cement and / or slag) at a level of 50% by weight of the dry mixture. Water was then mixed with the premix so as to obtain a cement slurry in proportions of around 20% ± 5% by mass. Time Speed Actions 0 to 10 "Slow Blending of dry binders 10" to 1'00 Slow Addition of solution until the formation of dumplings 1'00 to 2'00 Fast Mixing of dumplings 2'00 to 3'00 Slow Addition of the rest of the solution 3 'to 5'30 "Semi rapid Mixing A mixer Rayneri Turbotest Mixer (MEXP-101) comprising deflocculating blades and whose speed varies from 1000 rpm to 400 rpm according to the volume of grout was used to maintain the grout in continuous agitation in the storage tank after its manufacture and before its pumping to be injected into the static mixer.The grout can be pumped with a Moineau type positive displacement pump, for example: SeepexTM BN025 eccentric screw pump -12 - W commission 244921.
    [0009] The aqueous foam was obtained by foaming a solution of water and a foaming agent such as Proprump 26 produced by Propump. Propump 26 is an animal protein with a molecular weight of about 6000 Daltons. The amount of water can vary from 75 to 98% by weight, for example around 80%.
    [0010] Other additives such as a thickening agent (eg, Kelcocrete 200 biopolymer), or an accelerator such as calcium chloride may be added but are not generally required. The aqueous foaming agent solution was co-introduced through the aerator with the pressurized air (range 1 to 6 bar) using a T-junction. The aqueous foam was generated in a controlled manner. keep on going. The aerator consists of a bed of SB30 type glass balls of diameter between 0.8 and 1.4 mm, packed in a tube length of 100 mm and diameter 12 mm. The cement slurry was contacted with the aqueous foam already circulated in the circuit and the foamed cement slurry was then obtained. The filling of the cells of the concrete block with the foamed slurry has been carried out continuously by a pipe which is handled from one cell to another. Although in this example the implementation has been manual, the implementation may be automated, in particular because the cement slurry does not contain a setting accelerator such as calcium aluminate. Example 1: Refilling a fresh block According to a first variant of the invention, the blocks of cement blocks (2) made according to the method described above with the concrete of Formula F33 have been filled with a cement foam (3) as soon as it leaves the press (vibrocompactor) and demolding said block (2). After filling with the cement foam, the composite blocks (1) were placed under a Styrodur lid and left in the room for 24 hours. The appearance of these composite blocks (1) is shown in FIGS. 1 and 2. This process was repeated with a lightweight cement block of Formula F 41. EXAMPLE 2: Filling a Waterproof Block According to a second variant of the invention, cement blocks made according to the method described above with the concrete of Formula F34 have been placed under a Styrodur lid in order to reproduce the curing conditions generally observed in the production plants. of masonry blocks. The temperature is close to 30% and the humidity is close to saturation. Once set and cured (at least 24 hours), the cells of these blocks were filled with "foam". These composite blocks were placed under a Styrodur lid and left in the room for 24 hours.
    [0011] Example 3: Filling a rehydrated dry block. According to a third variant of the invention, cement blocks made according to the method described above with the Formula F33 concrete (not waterproofed) were placed under a Styrodur lid for 48 hours in order to reproduce the cure conditions and generally observed in masonry block production plants. The temperature is close to 30% and the humidity is close to saturation.
    [0012] Once set and cured, the block was re-moistened by spraying with large amounts of water for 20 seconds. The cells of these blocks were then filled with cement foam. These composite blocks were placed under a Styrodur lid and left in the room for 24 hours.
    [0013] Example 4 Comparative Example: Filling a Commercial Cement Block A standard cement block from Fabemi was filled with cement foam (5). The external appearance of this composite block (4) after drying is shown in FIG. 3. Conclusion The cement foam of the composite blocks obtained according to the method of the invention and described above remained stable after drying. Not only was the foam secured to the walls from a visual point of view and no retraction was apparent, but said blocks were turned over to ensure that the foams adhered well to the walls. Foams have not been detached. The cement foam introduced into the cells of a standard cement block retracted and detached from the walls of the cells.
    [0014] The invention is not limited to the embodiments shown and other embodiments will become apparent to those skilled in the art. It is particularly possible to accelerate the setting of the composite blocks once the cement foam introduced into the cells by known methods such as heating.
