Description

<Desc/Clms Page number 1> <Desc / Clms Page number 1>

La présente invention a pour objet un nouveau type de charge pour des produits livrés prêts à l'emploi pour la réalisation de revêtements de parois, lesdits produits contenant des liants hydrauliques.  The present invention relates to a new type of filler for products delivered ready to use for the production of wall coverings, said products containing hydraulic binders.

De tels produits sont livrés en sacs et mélangés à de l'eau sur le chantier.  Such products are delivered in bags and mixed with water on site.

C'est le cas par exemple des enduits monocouches d'imperméabilisation.  This is the case for example of monolayer waterproofing plasters.

Par produits pour la réalisation de revêtement de parois selon l'invention, on comprend aussi bien les enduits d'imperméabilisation, c'est-à-dire les enduits extérieurs que les enduits intérieurs, les enduits à la chaux, les liants tels que les chaux hydrauliques naturelles et aériennes, les produits autonivellants de réagréages des sols ou les ciments collés.  By products for the production of wall coverings according to the invention, we understand both waterproofing coatings, that is to say exterior coatings as interior coatings, lime coatings, binders such as natural and aerial hydraulic lime, self-leveling products for re-leveling soils or bonded cements.

Pour la simplification de la description, les exemples de réalisation font essentiellement référence aux enduits monocouches.  For the simplification of the description, the embodiments essentially refer to monolayer coatings.

Les enduits monocouches ont essentiellement pour fonction le dressage, l'imperméabilisation et la décoration des parois extérieures en maçonnerie ou en béton.  Monolayer plasters essentially have the function of dressing, waterproofing and decorating exterior walls in masonry or concrete.

Les enduits connus sont généralement constitués de : - chaux, - liant hydraulique, minéraux calcaires ou siliceux et d'adjuvants spécifiques tels que des produits rétenteurs d'eau, des produits hydrofuges, des produits entraîneurs d'air...  The known coatings generally consist of: - lime, - hydraulic binder, limestone or siliceous minerals and specific additives such as water-retaining products, water-repellent products, air-entraining products, etc.

Ces produits livres en sac sont mélangés à de l'eau sur le chantier.  These bagged products are mixed with water on site.

Il est connu d'ajouter à ces produits des charges pour obtenir des caractéristiques particulières.  It is known to add fillers to these products to obtain particular characteristics.

La charge selon l'invention vise à permettre la réalisation d'enduit ou autres produits de revêtement tels que définis plus haut à basse densité par exemple avec une densité de 0,9 et avec de très bas modules d'élasticité par exemple avec un module d'élasticité de 15000 decanewton et dont l'application soit possible sur des supports variés tels que : - brique de terre crue, - agglomères en béton, - béton banché, - béton cellulaire, - brique de terre cuite,  The filler according to the invention aims to allow the production of plaster or other coating products as defined above at low density for example with a density of 0.9 and with very low elastic moduli for example with a modul of elasticity of 15,000 decanewton and the application of which is possible on various substrates such as: - raw earth brick, - concrete agglomerates, - shuttered concrete, - aerated concrete, - terracotta brick,

<Desc/Clms Page number 2><Desc / Clms Page number 2>

- et tous supports anciens.  - and all old supports.

A cet effet, la charge pour produit de revêtement de paroi selon l'invention se caractérise essentiellement en ce qu'elle est constituée de sable de béton cellulaire ce qui permet de réaliser des produits à basse densité avec un très bas module.  For this purpose, the charge for wall covering product according to the invention is essentially characterized in that it consists of cellular concrete sand which makes it possible to produce low density products with a very low modulus.

Par produits pour la réalisation de revêtement de parois selon l'invention, on comprend aussi bien les enduits d'imperméabilisation, c'est-à-dire les enduits extérieurs que les enduits intérieurs, les enduits à la chaux, les liants tels que les chaux hydrauliques naturelles et aériennes, les produits autonivellants de réagréages des sols ou les ciments collés.  By products for the production of wall coverings according to the invention, we understand both waterproofing coatings, that is to say exterior coatings as interior coatings, lime coatings, binders such as natural and aerial hydraulic lime, self-leveling products for re-leveling soils or bonded cements.

Le sable de béton cellulaire est obtenu par broyage de matériaux de construction en béton cellulaire. Les matériaux en béton cellulaire broyés sont des déchets.  Aerated concrete sand is obtained by grinding aerated concrete building materials. Crushed aerated concrete materials are waste.

L'enduit monocouche d'imperméabilisation adapté pour tous supports autorisés pour les enduits monocouches permettant de réaliser des enduits à basse densité avec de très bas modules, ledit enduit utilisant une charge est constitué de (en % en poids rapporté au poids du produit sec) - 5% d'un liant, - 15% de chaux naturelle, - 60% de minéraux, calcaires et siliceux, - 1 % à 60% de sable de béton cellulaire, des adjuvants dont : - des rétenteurs d'eau, - des produits hydrofuges, - des produits entraîneurs d'air.  The single-layer waterproofing coating suitable for all supports authorized for single-layer coatings making it possible to produce low-density coatings with very low modules, said coating using a filler consists of (in% by weight relative to the weight of the dry product) - 5% of a binder, - 15% natural lime, - 60% of minerals, limestones and siliceous, - 1% to 60% of cellular concrete sand, additives including: - water retentants, - water repellents, - air entraining products.

La charge selon l'invention est constituée de sable de béton cellulaire. Le béton cellulaire est un béton léger, constitué par un mélange de liants hydrauliques et d'agrégats fins, ayant subi un traitement mécanique, physique ou chimique destiné à réaliser dans sa masse une multitude de pores sphériques.  The charge according to the invention consists of cellular concrete sand. Aerated concrete is a light concrete, made up of a mixture of hydraulic binders and fine aggregates, having undergone a mechanical, physical or chemical treatment intended to produce in its mass a multitude of spherical pores.

Le sable de béton cellulaire est obtenu par une opération de broyage d'éléments de construction en béton cellulaire non utilisés et donc considérés comme des déchets.  Cellular concrete sand is obtained by a grinding operation of cellular concrete construction elements which are not used and are therefore considered as waste.

Le broyage permet d'obtenir un matériau granulaire allégé puisque intégrant les pores sphériques de très petites dimensions.  Grinding provides a light granular material since it integrates very small spherical pores.

La granulométrie obtenue peut être de 0 à 1 millimètres.  The particle size obtained can be from 0 to 1 millimeters.

<Desc/Clms Page number 3> <Desc / Clms Page number 3>

Le granulat obtenu peut être soumis à une opération de séchage.  The granulate obtained can be subjected to a drying operation.

Le sable de béton cellulaire utilisé comme charge présente l'avantage de rendre le produit fini plus léger, plus fluide et donc plus facile à travailler.  The cellular concrete sand used as a filler has the advantage of making the finished product lighter, more fluid and therefore easier to work.

Suivant une forme préférée de réalisation, la charge de sable de béton cellulaire est introduite dans un mélange composé de (les % en poids étant rapporté au poids du produit sec), - chaux naturelle : 15%, - liant hydraulique : 5%, minéraux et calcaires et siliceux : 60%, sable de béton cellulaire : 20%, plus les produits d'adjuvants spécifiques tels que produits rétenteurs d'eau, les produits hydrofuges, les produits entraîneurs d'air, etc...  According to a preferred embodiment, the charge of aerated concrete sand is introduced into a mixture composed of (the% by weight being relative to the weight of the dry product), - natural lime: 15%, - hydraulic binder: 5%, minerals and limestone and siliceous: 60%, cellular concrete sand: 20%, plus specific additive products such as water-retaining products, water-repellent products, air-entraining products, etc.

L'eau est rajoutée au moment de la mise en oeuvre en proportion variable selon les conditions d'utilisation. Les proportions des différents composants sont susceptibles de varier. La proportion de sable de béton cellulaire peut notamment varier de 1% à 60%.  Water is added at the time of implementation in variable proportion according to the conditions of use. The proportions of the different components are likely to vary. The proportion of cellular concrete sand can in particular vary from 1% to 60%.

Il est apparu à l'usage qu'une proportion de sable de béton cellulaire de 10% à 40% présentait des avantages et était optimisée pour obtenir une bonne résistance mécanique et une très bonne perméabilité à la vapeur d'eau laissant ainsi respirer les supports tout en assurant une parfaite imperméabilité.  It has become apparent from use that a proportion of cellular concrete sand from 10% to 40% has advantages and is optimized to obtain good mechanical strength and very good permeability to water vapor, thus allowing the supports to breathe. while ensuring perfect waterproofness.

L'enduit obtenu selon l'invention peut être mis en oeuvre en une couche et en une passe la thixotropie du matériau permettant d'obtenir en une passe des dépôts de 20 à 40 millimètres.  The coating obtained according to the invention can be used in one layer and in one pass, the thixotropy of the material, making it possible to obtain deposits of 20 to 40 millimeters in one pass.

Le module d'élasticité très bas et son faible poids au m2 (14 à 15 kg) permet en outre de travailler d'un tout type de support tels que : - brique en terre cuite, bloc agglomère en béton, béton banché, béton cellulaire, - brique de terre cuite du type ancien, - brique de terre crue, et plus particulièrement tous vieux supports.  The very low modulus of elasticity and its low weight per m2 (14 to 15 kg) also makes it possible to work with any type of support such as: - terracotta brick, agglomerated concrete block, walled concrete, aerated concrete , - terracotta brick of the old type, - raw clay brick, and more particularly all old supports.

<Desc/Clms Page number 4> <Desc / Clms Page number 4>

Les essais effectués montrent que l'enduit obtenu parvient dans les 48h après la pose à une dureté normale, celui-ci étant au terme de ce délai parfaitement hydraté et carbonaté.  The tests carried out show that the coating obtained arrives within 48 hours after laying at a normal hardness, the latter being at the end of this period perfectly hydrated and carbonated.

Dans le cas des enduits à la chaux, on obtient une réduction très sensible de poids.  In the case of lime plasters, a very significant reduction in weight is obtained.

L'invention couvre également les produits incluant ladite charge. The invention also covers products including said filler.
