Description

11546 Description o La presente invention concerne la compositions d'un liant pour mortier à l'usage de revetement,d'enduit, intérieur ou exterieur ou en mortier d'injection ou de houdage, maçonnerie ou de liant pour béton. Ce liant est constitué d'un mélange à base de chaux et de métakaolin, le tout ensuite mélangeable avec un sable propre à la construction, de 0/1 0/2 0/4 appelé sable à bâtire, fin ou très fin, pour l'obtention d'un mortier, ou mélange prêt à l'emploi. Ce dit mélange peut permettre une protection des parois qu'il recouvre, ainsi qu'un rendu esthétique, ou dans le cas de la maçonnerie, il permrnetra l'assemblage io de melon, de pierre ou de toutes pièce à maçonner; Il pourra servir aussi de mortier d'injection dans en maçonnerie. Le présent liant pourra servir de liant pour la fabrication de béton en le mélangeant à un sable et du grave. Le pourcentage du mélange chaux et métakaolin oscillera entre 10 15 et 40% de métakaolin pur pour 60 à 90% de chaux pour la construction. Le pourcentage de sable sera entre 40 et 70% dans la composition total du mortier. Le principe est dans ce dit mélange l'intégartion de la chaux naturel hydraulique ou chaux formulae ou chaux aérienne. Cette invention permet de créer des mortier ou des bétons 20 hautement hydraulique sans ajout de ciment ou pouzzolane.The present invention relates to the compositions of a mortar binder for use as a coating, a plaster, indoors or outdoors, or as an injection or welding mortar, masonry or concrete binder. This binder consists of a mixture of lime and metakaolin, then mixed with a clean sand construction, 0/1 0/2 0/4 called building sand, fine or very thin, for obtaining a mortar, or mixture ready for use. This said mixture may allow a protection of the walls that it covers, as well as an aesthetic rendering, or in the case of masonry, it will permit the assembly of melon, stone or any piece of masonry; It can also be used as an injection mortar in masonry. The present binder can be used as a binder for the manufacture of concrete by mixing it with sand and gravelly. The percentage of the mixture lime and metakaolin will oscillate between 10 and 40% of pure metakaolin for 60 to 90% of lime for the construction. The percentage of sand will be between 40 and 70% in the total composition of the mortar. The principle is in this mixture the integration of the natural hydraulic lime or lime formulated or aerated lime. This invention makes it possible to create highly hydraulic mortars or concretes without the addition of cement or pozzolan.

2 3011546 La présente invention, est un mélange de chaux pour la construction et de métakaolin, dans des proportion ci-dessus , puisque l'usage est multiple: 1 dans les enduits 2 Dans la maçonnerie en tant que mortier de hourdage 3 Dans la maçonnerie avec du grave il permet la fabrication de béton. Les interest de c edit mélange sont multiples 1 -Le métakaolin, utilise la chaux libre en dispertion dans le mortier pour durcir, on évite ainsi le phénomène de tâche blanches en surface et de créer des desordre esthétique. 2 -H durcit plus rapidement qu'un enduit traditionnel à la chaux, 10 puisque'il prend à coeur comme un ciment avec l'eau, ou comme tout liant hydraulique 3 -Dans le cas de fabrication de béton avec comme liant un mélange de chaux et métakaolin, il permet une prise à Coeur, ou un durciessment de la matière en tout point, puisque la chaux ne durci 15 qu'au contact du CO2, le mélange se faisant avec de l'eau,. 4 -Du fait de sa resistance à la compression plus élevée qu'avec un mortier de chaux classique, les couches peuvent être moins épaisse. -Le dit mélange durcissant plus rapidemant que les enduits à la chaux, il permet donc d'accélérer les temps d'attente entre la pose des 20 couches d'enduits sur les murs. 6 -Le métakaolin ayant un indice de blancheur de 73, une fois méangé avec la chaux, il permet au mortier d'être coloré ou pigmenté, de n'importe quelle, couleur, sans que celui-ci ne soit plus foncé. 7 -Etant donné une cuisson proche de celle des chaux pour la 25 construction, soit environ 1000°C, il se mélange très parfaitement à la chaux, endevenant un liant dit bélitique. 8 - Melangé ou un sable très fin, ou des fillers ou de la poudre de marbre, ou toute poudre innerte compatible avec la constrcution, il permet de faire un mortier de réparation pour pierre, ayant selon le 30 poucentage du mélange entre métakolin et chaux, une dureté similaire de celle de la pierre, à réparer.The present invention is a mixture of lime for construction and metakaolin, in the above proportion, since the use is multiple: 1 in coatings 2 In masonry as mortar 3 In masonry with serious it allows the manufacture of concrete. The interests of this mixture are multiple 1 - The metakaolin, uses the free lime in dispersion in the mortar to harden, one thus avoids the phenomenon of white spots on the surface and to create aesthetic disorder. 2 -H hardens faster than a traditional lime plaster, 10 since it takes to heart like a cement with water, or like any hydraulic binder 3 -In the case of manufacturing concrete with as binder a mixture of lime and metakaolin, it allows a setting heart, or a hardcessment of the material in every way, since the lime only cured 15 in contact with CO2, mixing with water ,. Due to its higher compressive strength than with conventional lime mortar, the layers may be less thick. The said hardening mixture is faster than the lime renders, it thus makes it possible to accelerate the waiting time between the laying of the layers of plaster on the walls. 6 -The metakaolin having a whiteness index of 73, once mixed with lime, it allows the mortar to be colored or pigmented, of any color, without it being darker. Since cooking is close to that of lime for the construction, ie about 1000 ° C., it mixes very well with lime, becoming a belitic binder. 8 - Melange or a very fine sand, or fillers or marble powder, or any inner powder compatible with constrcution, it allows to make a repair mortar for stone, having according to the percentage of the mixture between metakolin and lime , a hardness similar to that of stone, to repair.
