Abstract

Use of bulk waterproofing compound, characterised in that it contains 1 % of iron oxide, in the preparation of mortars containing lightweight granulates used for the manufacture of construction units in the building industry. The units in question have a very low density which provides them with exceptional thermal results and have physical strength which makes them suitable for use as supporting units, which was not the case hitherto. The abovementioned units have a plaster-finished face making it unnecessary for a plasterer to be involved on work sites. The physical, thermal and plaster appearance results of these units permit a considerable reduction in the cost of construction, especially with regard to manpower. The technique of compression of the material in the moulds determines the physical and thermal results to be attained.

Description

La présente invention concerne une nouvelle utilisation du produit hydro
fuge , objet du brevet principal et ci-apres dénommé " Produit A " , dans la
fabrication de matériaux composés de " mortiers à granulats légers " . Ces gra
nulats sont des billes de polystyrène dont 80 à 95 % cnt un diamètre de 6 milli
mètres et 5 à 20 0 un diamètre de 1 à 4 millimètres
Il a déjà été fait mention de l'emploi de polystyrène dans la fabrication
de béton légers dans différentes revues telle la " Revue des Matériaux de ronstruc
tion " ainsi que dans certains brevets dont es revendications faisaient mention
de l'emploi du sang animal
Dans la présente invention , les mortiers à granulats légers sont ccnstits
d'une part de ciment et d'eau , dans des proportions variant selon les qualités
demandes aux matériaux , auxquels on ajoute le " Produit A " à raison de.4 du
poids du ciment . Le mélange terminé , on obtient une barbotine de ciment à laquelle
on ajoute les billes de polystyrène .Les matériaux ainsi obtenus ont une masse voir
mique pouvant descendre à 250 Kg/n? et sont d'excellents isolants thermiques et pho
niques
A cette composition , il est possible d'ajouter des perfluoroalRyl-éthylènes (carbures fluorés ) afin de réduire d'avantage la densité de ces mortiers
Les résistances mécaniques obtenues avec ces mortiers à granulats légers
grace à l'utilisation du " Produit A " rendent ce matériau apte à l'emploi dans l'ici
dustrie du bâtiment ce qui , compte tenu de sa masse volumique , de ses qualités
d'isolant tant thermique que phonique et sa propriété d'être étanche en fait un
matériau d'avant garde
Exemple nO 1 de l'emploi de ce matériau : fabrication de hourdis de plancher
avec une densité de 0,320 , performances thermiques = 0,07 W et K = O,3u wimLC
- ciment 250 Kg/n?
- eau 93 Litres
- " Produit A " 1 Kg
- billes de polystyrène 1 m >
Exemple nO 2 de l'emploi de ce matériau : fabrication de blocs porteurs avec
une densité de 0,450 , performances thermiques = 0,10 W ,résistance compression de
minimum 16 bars
- ciment 350 Kg/n?
- eau 149 litres
- " Produit A " 1,4 Kg
- billes de polystyrène 1 n?
Afin d'ajouter aux performances de ce matériau , il est coulé lors de la
fabrication des éléments de construction , et en fond de moule , une pâte falte
de plâtre et d'eau qui fait prise en même temps que le mortier ( voir le procédé
décrit ci-après ) et qui permet d'obtenir une face finie plâtre , devant suprimer
l'intervention du plâtrier iors de la construction
La maçonnerie des blocs à constitution de mortier léger reste du domaine traditionnelle et la liaison millimètique des éléments est assurée par une barbotine de ciment du trême type que celle employée pour la confection du mortier léger . Cette liaison mlllimètrique suprime les ponts thermiques au niveau des joints de maçonnerie traditionnelle
Procedé de fabriation des éléments en mortier léger : après avoir malaxé les différents composants du mortier durant trois minutes , celui est mis dans les moules après qu'une pâte de plâtre aie été appliquée dans le fond des moules
Le mortier à granulats légers doit remplir à ras-bord les moules qui sont spécialement conçus . Cette opération terminée les moules sont placés sous presse et le mortier est comprimé en fonction de deux éléments qui sont d'une part la résistance phisique désirée et d'autre part le coéfficient thermique K recherché . Plus le mortier est comprimé , plus il est résistant et moins isolant
Une fois la compression terminée , l'élément est démoulé instantanément puis stocké pendant une durée minimume de sept jours The present invention relates to a new use of the hydro product
fuge, subject of the main patent and hereinafter referred to as "Product A", in the
manufacture of materials composed of "light aggregate mortars". These gra
nulls are polystyrene beads of which 80 to 95% cnt a diameter of 6 milli
meters and 5 to 20 0 a diameter of 1 to 4 millimeters
Mention has already been made of the use of polystyrene in the manufacture
of lightweight concrete in various journals such as the "Revue des Matériaux de ronstruc
"as well as in certain patents mentioned in the claims
the use of animal blood
In the present invention, light aggregate mortars are included.
on the one hand cement and water, in proportions varying according to the qualities
requests to materials, to which we add "Product A" at the rate of.4 of
weight of cement. When the mixture is finished, a cement slip is obtained, to which
add the polystyrene beads. The materials thus obtained have a mass see
mique which can go down to 250 Kg / n? and are excellent thermal and pho insulators
picnics
To this composition, it is possible to add perfluoroalRyl-ethylenes (fluorinated carbides) in order to further reduce the density of these mortars
The mechanical strengths obtained with these light aggregate mortars
through the use of "Product A" make this material suitable for use in the here
of the building industry which, given its density, its qualities
both thermal and sound insulation and its property of being waterproof makes it
avant-garde material
Example 1 of the use of this material: manufacture of floor slabs
with a density of 0.320, thermal performance = 0.07 W and K = 0.3u wimLC
- cement 250 Kg / n?
- water 93 Liters
- "Product A" 1 Kg
- polystyrene beads 1 m>
Example No. 2 of the use of this material: manufacture of load-bearing blocks with
a density of 0.450, thermal performance = 0.10 W, compression resistance of
minimum 16 bars
- cement 350 Kg / n?
- water 149 liters
- "Product A" 1.4 Kg
- polystyrene beads 1 n?
In order to add to the performance of this material, it is poured during the
manufacture of construction elements, and at the bottom of the mold, a dough
plaster and water which sets at the same time as the mortar (see the process
described below) and which makes it possible to obtain a finished plaster face, to be suppressed
intervention of the plasterer during construction
The masonry of light mortar blocks remains the traditional domain and the millimeter connection of the elements is ensured by a cement slip of the same type as that used for the preparation of light mortar. This limitless connection overcomes thermal bridges at the level of traditional masonry joints
Light mortar components manufacturing process: after mixing the various components of the mortar for three minutes, it is put in the molds after a plaster paste has been applied to the bottom of the molds
The light aggregate mortar should fill the specially designed molds to the brim. Once this operation is complete, the molds are placed under a press and the mortar is compressed according to two elements which are on the one hand the desired physical resistance and on the other hand the desired thermal coefficient K. The more compressed the mortar, the more resistant and less insulating
Once compression is complete, the element is removed from the mold instantly and then stored for a minimum of seven days.
