Abstract
Description
L'inventior. concerne un procédé pour la fabrication, notaamel! in situe de mortier cellulaire. The inventior. concerns a manufacturing process, notaamel! in situ with cell mortar.
Elle concerne aussi les nouveaux produits obtenus à l'aide de ce procédé. It also relates to new products obtained using this process.
Le mortier allégé est un produit bien connu qui prend de plus en plus d'importance, comme matériaux de revetement en particulier, vis à vis du mortier ordinaire. Il présente, entre autres avantages, ceux de posseder une densité plus faible et des propriétés améliorées d'isolation thermique et phonique. Light mortar is a well-known product which is becoming more and more important, as a coating material in particular, compared to ordinary mortar. It has, among other advantages, those of having a lower density and improved thermal and sound insulation properties.
Cependant, la fabrication actuelle des mortiers allegés ne va pas sans inconvenients. C'est ainsi par exemple que jusqu'à présent, la fabrication des mortiers allegés prêt à l'emploi, se fait en incorporant en grande quantité au ciment et autres composants mineraux, des produits legers tels que perlite, vermiculite, polystyr;ne à l'état expansé, qui sont des produits trés onéreux et qui ne permettent pas toujours d'obtenir des densités inférieures à i, au détriment des caractéristiques techniques des matériaux obtenus. However, the current manufacture of lightweight mortars is not without drawbacks. Thus, for example, until now, the manufacture of ready-made lightweight mortars is done by incorporating in large quantities into cement and other mineral components, light products such as perlite, vermiculite, polystyrene; the expanded state, which are very expensive products and which do not always make it possible to obtain densities less than i, to the detriment of the technical characteristics of the materials obtained.
La présente invention a pour objet, un procédé de fabrication des mortiers allégés cellulaires de densité égale à 7 ou inférieure telle que 0.8 - 0,6 0,4 qui dans une large mesure est dénué des inconvénients présentés par les procédés actuellement connus et permet d'obtenir des produits nouveaux présentant des avantages particuliers forts interessants. The subject of the present invention is a process for manufacturing lightweight cellular mortars with a density equal to 7 or less such as 0.8 - 0.6 0.4 which, to a large extent, is devoid of the drawbacks presented by the methods currently known and allows '' obtain new products with very interesting particular advantages.
Le procédé selon l'invention est caractérisé essentiellement en ce qu' avant d'être transformé en mortier allegé cellulaire, propre à étire conformé en éléments d'utilisation, le ciment constitutif additionné de préférence de ses ingrédients mineraux conventionnels, voire de tous autres produits appropriés est mélangé avec au moins un agent tensio actif, au moins une laine de verre ou de roche, cet ensemble de corps étant dispersé au sein d'une émulsion du type gaz. The method according to the invention is essentially characterized in that before being transformed into light cellular mortar, suitable for stretching conformed to elements of use, the constituent cement preferably added with its conventional mineral ingredients, or even any other products suitable is mixed with at least one surfactant, at least one glass wool or rock wool, this set of bodies being dispersed within a gas type emulsion.
Le procédé tel que décrit, offre la particularité de pouvoir être pratiqué dans des appareils courants, suivant des méthodes opératoires simples, par une main d'oeuvre non spécialisée, en tout endroit convenable. The method as described offers the particularity of being able to be practiced in current devices, according to simple operating methods, by unskilled labor, in any suitable place.
C'est à dire que l'on peut pour la première fois obtenir par le procédé selon l'invention des mortiers cellulaires prêt à l'emploi de densité differente, on ne se trouve plus limité à certaines densités comme c'était le cas auparavent. That is to say that it is possible for the first time to obtain, by the process according to the invention, ready-to-use cellular mortars of different density, we are no longer limited to certain densities as was the case previously. .
Enfin le procédé melon l'inventior. permet d'obtenir des reveterents conformés en mortier cellulaire dans lequel les pores sont fermés, c'est à dire onstitués par de- alvéoles clos. Il est bien certain que te tels revetem.ents présentent des propriétés d'isolation ther--cue et phonique accrues par rapport aux éléments analogues connus. Finally, the inventive melon process. makes it possible to obtain reveterents shaped in cellular mortar in which the pores are closed, that is to say formed by closed cells. It is quite certain that such coverings have improved thermal and sound insulation properties compared to known analogous elements.
Ii est manifeste égalenent que les revetements et les éléments du procédé selon l'invention offrent ainsi une bien moindre rétention à l'eau et, par la même, une très bonne stabilité dimensionnelle, ce qui constitue un avantage indiscutable. It is also evident that the coatings and the elements of the process according to the invention thus offer much less water retention and, by the same token, very good dimensional stability, which constitutes an indisputable advantage.
Le procédé selon l'invention peut être mis en oeuvre de differentes manieres, l'essentiel etant avant tout d'assurer un mélange bien homogène, entre eux, des divers constituants du mortier cellulaire et a'obtenir des alvéoles clos les plus petits possibles, pouvant être inférieurs al millimètre de diamètre, afin d'obtenir les meilleures caractéristiques. The method according to the invention can be implemented in different ways, the main thing being above all to ensure a very homogeneous mixture, between them, of the various constituents of the cell mortar and to obtain the smallest possible closed cells, may be less than a millimeter in diameter, in order to obtain the best characteristics.
D'une manière ou d'une autre, on aboutit toujours aux densités recherchées. In one way or another, we always arrive at the desired densities.
Ce mortier prêt à l'emplois tout en possedant le temps de conservation d'un mortier classique, peut être également coulé dans des moules aux formes désirées pour l'obtention d'éléments définitifs de materiaux de construction par exemple et, connaitre au bout de quelques heures un durcissement suffisant pour autoriser sa manipulation. Les éléments qu'il fournit ont une structure à cellules fermées et possedent de bonnes résistances à la traction et à la compression.This ready-to-use mortar while having the shelf life of a conventional mortar, can also be poured into molds with the desired shapes for obtaining final elements of construction materials for example and, after a few hours sufficient hardening to allow handling. The elements it supplies have a closed cell structure and have good tensile and compressive strengths.
De plus, l'utilisation du mortier dans les machines à projeter ne modifie en rien sa structure cellulaire et du fait de sa grande tyxotropie l'accrochage sur le support peut être réalisé en grande épaisseur en une seule passe. In addition, the use of mortar in spraying machines does not in any way modify its cellular structure and, because of its large tyxotropy, it can be attached to the support in great thickness in a single pass.
A titre de mode de réalisation, l'invention va être décrite plus en détail à l'aide d'exemples ci-après, qui ne sauraiert, en aucun cas, limiter de si peu que ce soit la portée de la dite invention. By way of embodiment, the invention will be described in more detail with the aid of examples below, which in no case will be able to limit so little that this is the scope of the said invention.
EXEMPLE 1
Densité 1 d'un mortier sec constitué de
115 Kg de ciment blanc
15 Kg de chaux hydraulique
100 Kg de sable 0.3
50 Kg de calcaire 0.3/0.7 additionné des ingrédients usuels dans un tel mortier. EXAMPLE 1
Density 1 of a dry mortar consisting of
115 kg of white cement
15 Kg of hydraulic lime
100 Kg of sand 0.3
50 Kg of limestone 0.3 / 0.7 added with the usual ingredients in such a mortar.
C1 est à dire résine, stéarate, methyl ethyl cellulose. C1 is to say resin, stearate, methyl ethyl cellulose.
On prend à cette formule
2.650 Kg auxquels on ajoute,
0.100 Kg de laine de verre type isolation et réduite en poudre
0.250 Xg d'agent tensio actif
soit : 3.000 KG
On mélange l'ensemble des composants dans un malaxeur jusqu'à dégagement des gaz et l'expansion de la poudre qui sèche immédiatement. Ce mélange de 3 Kg est introduit dans un malaxeur ot se trouve 1 000 Kg de mortier sec, on malaxe l'ensemble pendant quelques minutes et l'on ensache dans des sacs de 25 Kg pret d l'emploi. A ces sacs l'on ajoute, sur le chantier, l'eau necessaire au gachage, pour obtenir un mortier de revetement cellulaire de densité 1. We take this formula
2.650 Kg to which we add,
0.100 Kg of glass wool type insulation and reduced to powder
0.250 Xg of surfactant
or: 3.000 KG
All the components are mixed in a kneader until the gases are released and the powder which dries immediately expands. This 3 Kg mixture is introduced into a kneader ot is 1000 Kg of dry mortar, the whole is kneaded for a few minutes and it is bagged in 25 Kg bags ready for use. To these bags are added, on site, the water necessary for mixing, to obtain a cell coating mortar of density 1.
EXEMPLE 2
Densité 0.8
On prend 4 Kg de poudre réalisé comme dans l'exemple 1 que l'on addition- nent à 1 000 Kg de mortier sec afin d'obtenir la densité 0.8
Densité 0.6 on ajoute 5 Kg de poudre à 1 000 Kg de mortier sec
Densité 0.4 on ajoute 6 Kg de poudre à 1 000 Kg de mortier sec
On constate qu'il y a repetitivité constante des densités et que les doses de produit sont infimes, 3 pour 1 000 pour une densité de 1 ce qui semble unique sur le plan économique par rapport à ce qui existe. EXAMPLE 2
Density 0.8
Take 4 Kg of powder produced as in Example 1 which is added to 1000 Kg of dry mortar in order to obtain the density 0.8
Density 0.6 we add 5 Kg of powder to 1000 Kg of dry mortar
Density 0.4 6 kg of powder is added to 1000 kg of dry mortar
It is noted that there is constant repetitivity of the densities and that the doses of product are tiny, 3 per 1000 for a density of 1 which seems unique economically compared to what exists.
