  "Procédé de fabrication de mortiers et bétons légers" 
La présente invention se rapporte à un procédé, simple et économique, de fabrication de mortiers et de bé- tons imperméables , légers et isolants. 



   Plusieurs procédés sont déjà connus pour produi- re des bétons légers, décrits sous diverses appellations tel -les que : béton poreux, gaso-béton, béton cellulaire etc. 



  Mais la fabrication de ces bétons réclame, soit l'action des gaz provenant de la combinaison des métaux ou des composés de ceux-ci, introduits expressément dans les mélanges,avec l'eau, la chaux, le ciment ou d'autres produits similaires, soit la présence de substances ;argilés, mucillages, algues, gélatines, savons, résines, graisses, brais, goudrons, ou encore de sulfures, chlorures, carbures, etc. ajoutés spé- cialement en vue de provoquer le gonflement des mélanges ou des mortiers. De telle sorte que des manipulations délica- tes, ainsi que des dosages répétés, sont nécessaires, qui li- mitent le champ d'exploitation industrielle de ces procédés. 



  Pour faciliter celle-ci on a essayé d'enrober préalablement 

 <Desc/Clms Page number 2> 

 les métaux ou les composés de ceux-ci, ou bien la chaux ou le ciment,ou encore les autres matières des mélanges, au moyen de graisses, de résines, d'argiles, ou de produits si- milaires, mais la disproportion énorme des volumes à mélan- ger intimement comme la nature des corps en présence nuit considérablement aux opérations et à la répartition réguliè- re des expansifs dans la masse et par suite à l'homogénéité des produits.

   D'autre part les mortiers ainsi fabriqués ne se prêtent pas, en raison de leur composition, à l'emploi des produits durcissants ou hydrofuges, que l'on trouve couram- ment dans le commerce, et dont on se sert déjà dans la fabri- cation des bétons à base de chaux ou de magnésie. - 
La présente invention a pour objet la fabrication de mortiers et de bétons légers, imperméables, isolants,sans adjonction à la chaux, au plâtre, au ciment ou à la magnésie d'autres matières que celles qui sont habituellement employ- ées pour la fabrication des bétons de densité normale, imper -méabilisés de la manière connue, le procédéétant caractérisé par le mode opératoire nouveau dans lequel on soumet les ma- tières insolubles, préalablement à leur introduction dans les mélanges fluides,

   à une pulvérisation suffisante pour qu'el- les flottent dans le liant durant le temps révolu à la durée de prise ; les mélanges étant à cet effet agités et dilatés plus ou moins ,suivant leur composition et les besoins, dans des appareils, appropriés aussi pour répartir uniformément toutes les matières ténues ou colloïdales dans le fluide. 



   L'inventeur a trouvé que les très-fines particules résultant de la pulvérisation de certaines matières addition- nelles des mortiers hydrauliques, notamment les silicates et les aluminates, porphyres et laitiers, ici cités simplement à titre d'exemple, passent à l'état gélatineux dans les mé- langes à base de chaux ou de magnésie, lorsqu'ils sont con- 

 <Desc/Clms Page number 3> 

 convenablement agités avec ces mélanges dans des appareils appropriés ;

   et que cette matière gélatineuse reste en sus -pension assez longtemps pour permettre aux mélanges d'em- prisonner des bulles d'air ou de gaz qu'ils conservent jus -qu'à la prise complète du mortier ;la chaux, le ciment ou les autres substances des mélanges étant parfois addition- nés de levures chimiques ou baking powder, suivant l'usage connu pour provoquer le gonflement et faciliter aux mélan- ges d'emprisonner des bulles d'air ou de gaz qu'ils conser- vent jusqu'à la prise complète du mortier. 



     Il a   reconnu qu'on peut augmenter l'état gélati- neux des mélanges par l'addition, en petites quantités, de sulfates ou de carbonates alcalins, ou par l'introduction de silice, d'alumine ou de toute autre matière similaire, gélatineuses. 



   Dans la fabrication des bétons par notre procédé les mortiers peuvent être coulés directement soit en place, soit dans des moules, ou bien être mélangés, préalablement au coulis, avec des mortiers de densités différentes, qui sont ensuite brassés au degré nécessaire à la légèreté , l'imperméabilité ou l'isolation que l'on veut obtenir.

  "Manufacturing process for light mortars and concrete"
The present invention relates to a simple and economical process for manufacturing waterproof, light and insulating mortars and concrete.



   Several processes are already known for producing lightweight concrete, described under various names such as: porous concrete, gas concrete, cellular concrete, etc.



  But the manufacture of these concretes requires either the action of gases resulting from the combination of metals or compounds thereof, expressly introduced into the mixtures, with water, lime, cement or other similar products , or the presence of substances; clays, mucillages, algae, gelatins, soaps, resins, greases, pitches, tars, or even sulphides, chlorides, carbides, etc. specially added for the purpose of causing swelling of mixtures or mortars. So that delicate manipulations, as well as repeated dosages, are necessary, which limit the field of industrial exploitation of these processes.



  To facilitate this, we tried to coat beforehand

 <Desc / Clms Page number 2>

 metals or compounds thereof, or lime or cement, or other materials of mixtures, by means of greases, resins, clays, or similar products, but the enormous disproportion of volumes to be intimately mixed, as the nature of the bodies present, considerably harms the operations and the regular distribution of the expansives in the mass and consequently the homogeneity of the products.

   On the other hand, the mortars thus manufactured do not lend themselves, because of their composition, to the use of hardening or water-repellent products, which are commonly found in commerce, and which are already used in the manufacture. - cation of concrete based on lime or magnesia. -
The present invention relates to the manufacture of mortars and lightweight concrete, waterproof, insulating, without adding lime, plaster, cement or magnesia other materials than those which are usually used for the manufacture of concrete. concrete of normal density, impermeable in the known manner, the process being characterized by the new operating mode in which the insoluble materials are subjected, prior to their introduction into the fluid mixtures,

   spraying sufficient so that they float in the binder during the time elapsed to the setting time; the mixtures being for this purpose agitated and dilated more or less, according to their composition and the needs, in apparatuses, also suitable for uniformly distributing all the fine or colloidal matters in the fluid.



   The inventor has found that the very fine particles resulting from the spraying of certain additional materials in hydraulic mortars, in particular silicates and aluminates, porphyries and slags, here cited simply by way of example, pass to the state. gelatinous in mixtures based on lime or magnesia, when they are

 <Desc / Clms Page number 3>

 suitably stirred with these mixtures in suitable apparatus;

   and that this gelatinous material remains in suspension long enough to allow the mixtures to trap air or gas bubbles which they retain until the complete setting of the mortar; lime, cement or the other substances of the mixtures being sometimes added with chemical yeasts or baking powder, according to known usage to cause swelling and to facilitate the mixtures to trap air or gas bubbles which they retain until 'when the mortar sets completely.



     He recognized that the gelatinous state of mixtures can be increased by the addition, in small quantities, of alkali sulphates or carbonates, or by the introduction of silica, alumina or the like, gelatinous.



   In the manufacture of concrete by our process, the mortars can be poured directly either in place or in molds, or else be mixed, prior to the grout, with mortars of different densities, which are then stirred to the degree necessary for lightness, the impermeability or insulation that we want to obtain.
