" Méthode pour la fabrication d'objets en pierre artificiel- le par centrifqgation dans un moale ". l'invention est relative à une méthode pour la fabrica- tion d'objets en pierre artificielle par centrifugation dans an moule et plas particulièrement à la fabrication de pieux creux, dont la surface extérieure peut être rendue lisse par frottage ou polissage.
Les méthodes asaelles pour la fabrication de pieux en béton par centrifagation ne peuvent être utilisées, pour ceci, puisque l'on considère comme nécessaire de mettre dans le matérisa une certaine quantité de sable comme matière de remplissage, et que ce sable rendrait inpossible le polissa- ge des pieax. D'antre part, si on omet le sable, lors da durcissement se produisent des fissures qui rendent le pro- duit défectueux. En outre, le temps de centrifugation était limité, parce que autrement il se serait produit une sépara- tion da matériaux, ce qai rendrait égalemant le produit dé- fectueux.
<Desc/Clms Page number 2>
L'invention consiste en ce que l'on prend comme mélange du ciment, de la pierraille et de l'eau, par conséquent, ana composition da même genre qae pour le béton, mais sans sable et dans laquelle la pierraille est constitue de marbre oa d'au matériaa analogue, tandis que le ciment, peat être coloré, par exemple par addition de pendre provenant da polis- sage da marbre .
Ce mélange est fait dans an moule et soumis à une ac- tion centrifuge', aassi longtemps que la pierraille avec an remplissage de ciment, se soit déposée en ana couche contre la paro du moule.
Après la centrifugation, on détache da moale en frap- pant et on laisse la masse se pétrifier, après qaoi on donna à l'objet une surface extérieure lisse par frottage ,polissa- ge ou d'une autre manière.
De cette manière, on obtient un produit qui après la pétrification ne présente aacane ou presqu'aucune fissare, @ outre, il est très solide et on peat le frotter et le polir. la çentrifaga tion peat durer ainsi longtemps qae sen- le la quantité d'eau nécessaire pour la pétrification, ou approximativement cette quantité, soit demearée dans la masse projetée contre la paroi da moule, ce qai diminue encore les chances de fissurage. On peut aussi munir les pieux de béton d'une armature.
Le mélange pe at par exemple consister en parties égales de ciment et de morceaux de marbre s. après environ 7 à 10 minâtes une quantité suffisante d'eau est enlevée par cen- trifugation, alors l'objet est déjà dur et peut être enlevé da. moule .
Après quoi l'objet se pétrifie, après environ 3 à 4 jours, la surface extérieure est polie, ce qai permet d'en- lever par frottement les petites fissures éventuelles.

"Method for the production of artificial stone objects by centrifugation in a moale". the invention relates to a method for the manufacture of artificial stone objects by centrifugation in a mold and more particularly to the manufacture of hollow piles, the outer surface of which can be made smooth by rubbing or polishing.
The standard methods for the manufacture of concrete piles by centrifagation cannot be used for this, since it is considered necessary to put in the material a certain quantity of sand as filling material, and this sand would make it impossible to polish it. - age of the pieces. On the other hand, if the sand is omitted, during hardening cracks occur which make the product defective. Further, the centrifugation time was limited, because otherwise there would have been separation of the materials, which would also render the product defective.
<Desc / Clms Page number 2>
The invention consists in taking as a mixture of cement, stone and water, consequently, a composition of the same kind as for concrete, but without sand and in which the stone is made of marble. oa of similar materiaa, while cement, can be colored, for example by addition of hanging from marble polishing.
This mixture is made in a mold and subjected to a centrifugal action, so long as the stone with a filling of cement, is deposited in a layer against the side of the mold.
After centrifugation, the moale is stripped off and the mass is allowed to petrify, after which the object is given a smooth outer surface by rubbing, polishing or otherwise.
In this way, a product is obtained which, after the petrification, shows no acane or almost no fissure, besides, it is very solid and it is rubbed and polished. the centrifugation can thus last a long time that the quantity of water necessary for the petrification, or approximately this quantity, is demeared in the mass projected against the wall of the mold, which further decreases the chances of cracking. The concrete piles can also be fitted with reinforcement.
The mixture can for example consist of equal parts of cement and pieces of marble. after about 7 to 10 minutes a sufficient quantity of water is removed by centrifugation, then the object is already hard and can be removed. mold.
After which the object petrifies, after about 3 to 4 days, the outer surface is polished, this qai allows to remove by friction any small cracks.
