Abstract

A plaster substitute product comprises at least one binder and at least one mineral charge made up of talc, calcareous sand and siliceous sand. A typical composition for this plaster substitute (weight %) would be 8.5% white cement, 8.46% calcined lime, 2% talc with a granulometry of 20 microns, 40% silica sand with a granulometry between 0.1 and 0.6 mm, 40% calcareous sand with a granulometry of 130 microns, 0.7% resin, 0.1% methyl cellulose, 0.4% anti-bubble agent and 0.2% smectic clay.

Description

<Desc/Clms Page number 1>
Produit de substitution du plâtre. L'invention est du domaine des matériaux de construction et concerne un mortier hydraulique de substitution du plâtre. <Desc / Clms Page number 1>
Plaster substitute. The invention is in the field of construction materials and relates to a hydraulic plaster replacement mortar.

Le plâtre, utilisé traditionnellement pour enduire les surfaces murales intérieures, présente un certain nombre d'inconvénients. Un inconvénient majeur se situe au niveau de son temps de séchage relativement important. D'autre part, le plâtre possède une mauvaise résistance aux poinçonnements. Plaster, traditionally used to coat interior wall surfaces, has a number of drawbacks. A major drawback lies in its relatively long drying time. On the other hand, plaster has poor resistance to punctures.

Des produits de ragréage ont été mis au point mais leur utilisation est généralement limitée au rebouchage de trous et non pas au recouvrement de surfaces. D'autre part, la formulation de ces produits n'autorise pas leur projection par une machine. Patching products have been developed but their use is generally limited to filling holes and not covering surfaces. On the other hand, the formulation of these products does not allow their projection by a machine.

La présente invention propose donc un nouveau produit ne présentant pas les inconvénients du plâtre et pouvant être mis en oeuvre manuellement ou mécaniquement par des machines de projection. Les autres applications de ce produit sont aussi vastes que toutes les utilisations connues du plâtre. The present invention therefore provides a new product which does not have the disadvantages of plaster and which can be used manually or mechanically by spraying machines. The other applications for this product are as broad as all known uses of plaster.

Le produit selon l'invention se caractérise en ce qu'il comporte au moins un liant et au moins une charge minérale composée de talc, de sable calcaire et de sable siliceux. The product according to the invention is characterized in that it comprises at least one binder and at least one mineral filler composed of talc, calcareous sand and silica sand.

Selon une caractéristique de l'invention le liant est composé de ciment blanc et de chaux calcique. According to a characteristic of the invention, the binder is composed of white cement and calcium lime.

Selon une autre caractéristique de l'invention la charge minérale comporte du talc de granulométrie moyenne comprise entre 10 et 30 #tm. According to another characteristic of the invention, the mineral filler comprises talc with an average particle size of between 10 and 30 #tm.

Selon une autre caractéristique de l'invention la charge minérale comporte du sable siliceux de granulométrie moyenne comprise entre 0.1 et 0.6 mm. According to another characteristic of the invention, the mineral filler comprises siliceous sand with an average particle size of between 0.1 and 0.6 mm.

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

Selon une autre caractéristique de l'invention la charge minérale comporte du sable calcaire de granulométrie moyenne comprise entre 100 et 150 pm.  According to another characteristic of the invention, the mineral filler comprises calcareous sand with an average particle size of between 100 and 150 μm.

Selon d'autres caractéristiques de l'invention, le produit contient une résine, du méthyle de cellulose, un produit anti-bullant ainsi que de l'argile smectique. D'autres avantages et caractéristiques de l'invention apparaîtront à la lecture de la description ci-après de formes de réalisation de l'invention données à titre d'exemples non limitatifs. According to other characteristics of the invention, the product contains a resin, methyl cellulose, an anti-bubbling product as well as smectic clay. Other advantages and characteristics of the invention will appear on reading the following description of embodiments of the invention given by way of non-limiting examples.

Il est possible de donner à titre d'exemple la constitution, en pourcentage en poids, du produit selon l'invention Liants - Ciment blanc: 8.5% - Chaux calcique: 8.46% Charges minérales - Talc granulométrie 20.m : 2% - Sable siliceux granulométrie comprise entre 0.1 et 0.6mm : 40% - Sable calcaire granulométrie 130gm : 40% Autres - Résine (marque commerciale Drycryl ) : 0.7% - Méthyle cellulose: 0.1 - Antibullage : 0.04% - Argile smectique: 0.2% It is possible to give, by way of example, the constitution, in percentage by weight, of the product according to the invention Binders - White cement: 8.5% - Calcium lime: 8.46% Mineral fillers - Talc granulometry 20.m: 2% - Sand siliceous grain size between 0.1 and 0.6mm: 40% - Limestone sand grain size 130gm: 40% Other - Resin (Drycryl brand): 0.7% - Methyl cellulose: 0.1 - Anti-bubbling: 0.04% - Smectic clay: 0.2%

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

Les différentes proportions citées ci-dessus ne sont bien entendu pas limitatives et peuvent varier dans une proportion de plus ou moins 20% de la valeur indiquée sans que l'on ne sorte du cadre de la présente invention.  The different proportions mentioned above are of course not limiting and may vary in a proportion of more or less 20% of the value indicated without departing from the scope of the present invention.

L'utilisation de ciment blanc et de chaux calcique permet de donner au produit la couleur du plâtre. The use of white cement and lime can give the product the color of plaster.

Le mélange judicieux des charges minérales permet d'obtenir tout comme avec le plâtre une couleur très blanche et un velouté spécifique identique. The judicious mixture of mineral fillers makes it possible to obtain, just like with plaster, a very white color and an identical specific velvety texture.

L'addition d'argile smectique et de talc permet d'obtenir une meilleure thixotropie du mélange humide autorisant une mise en #uvre sans fluage identique à celle du plâtre. The addition of smectic clay and talc makes it possible to obtain a better thixotropy of the wet mixture allowing an implementation without creep identical to that of plaster.

L'addition d'un anti-bullant permet, sur des supports peu poreux, d'éviter la formation de bulles. The addition of an anti-bubbling agent makes it possible, on low porous supports, to avoid the formation of bubbles.

L'addition d'un méthyle cellulose permet, sur un support sec, d'éviter la dessiccation trop rapide du produit. The addition of a methyl cellulose makes it possible, on a dry support, to prevent the product from drying out too quickly.

L'addition de résine permet d'obtenir un module d'élasticité plus faible sur le produit sec. The addition of resin makes it possible to obtain a lower modulus of elasticity on the dry product.

Pour un sac de 25kg de produit il est nécessaire d'ajouter 5 à 7 litres d'eau puis de malaxer manuellement ou mécaniquement jusqu'à l'obtention d'une pâte homogène qui pourra être utilisée comme du plâtre. For a 25kg bag of product it is necessary to add 5 to 7 liters of water and then mix manually or mechanically until a homogeneous paste is obtained which can be used as plaster.
