Abstract

A finishing mortar is made up of 60-70 wt.% crushed granite, 8-14% ground glass, 0.5-2.5% finely divided silica and 15-25% of ethyl silicate based liquid binder. An Independent claim is included for a coating compound made with this finishing mortar.

Description

La présente invention concerne la fabrication à la mise en ceuvre d'un mortier de ragréage imitant le granite et adapté la restauration des #uvres sculptées en granite. Les mortiers de ragréage utilisés sur les #uvres sculptées en pierre sont généralement constitués d'un granulat similaire à la pierre d'origine lié par une chaux aérienne ou hydrauli que, coloré par des pigments minéraux et mouillé d' addi tionnée d'émulsion acrylique. Si ces mortiers sont satisfai sants les calcaires ils le sont beaucoup moins sur les gra nites, en raison d'une part de leur forte teneur en cal cium, ' préjudiciable à la conservation du granite sculpté en extérieur, car il peut induire la formation de sels solubles analogues au salpêtre (incompatibilité chimique), raison d'autre part de leur aspect qui ne peut imiter la très légère translucidité du granite. The present invention relates to the manufacture at the implementation of a patching mortar imitating granite and adapted the restoration of carved works in granite. The patching mortars used on stone carvings are generally made of a granulate similar to the original stone bonded by aerial or hydraulic lime, colored by mineral pigments and wetted with acrylic emulsion additive. . If these mortars are satisfactory the limestones are much less so on the graites, partly because of their high calcium content, which is prejudicial to the conservation of the carved granite outside, because it can induce the formation of soluble salts similar to saltpeter (chemical incompatibility), on the other hand because of their appearance which can not imitate the very slight translucency of granite.

I1 existe également des mortiers constitués d' granulat similaire à la pierre d'origine, lié par une résine organique, polyester, époxyde ou acrylique. Plus satisfaisant visuelle ment, leur comportement vis à vis de l'eau est cependant trop différent de celui des pierres d'origine, d'où un mauvais vieillissement en extérieur (incompatibilité physique). There are also mortars made of granulate similar to the original stone, bound by an organic resin, polyester, epoxy or acrylic. More visually satisfying, their behavior with respect to water is, however, too different from that of the original stones, resulting in poor aging outdoors (physical incompatibility).

Le mortier mis au point évite les inconvénients décrits ci-dessus. Après la prise, ce mortier est exclusivement consti tué de granite et de silice. Son aspect est satisfaisant : la translucidité des constituants composés de silice fait que la surface présente essentiellement l'aspect du granite entrant dans composition. Sa compatibilité chimique et physique est bien meilleure que celle des autres mortiers : la silice est très proche des constituants naturels du granite et, contraire ment à chaux, ne peut être impliquée dans la formation de sels solubles. The mortar developed avoids the disadvantages described above. After setting, this mortar consists exclusively of granite and silica. Its appearance is satisfactory: the translucency of the constituents composed of silica makes that the surface has essentially the appearance of the granite entering the composition. Its chemical and physical compatibility is much better than that of other mortars: silica is very close to the natural constituents of granite and, unlike lime, can not be involved in the formation of soluble salts.

Ce mortier et les produits nécessaires à son application (voir ' dessous : mise en ceuvre) sont fabriqués de la manière suivante 1) Le mortier - à 70% en poids de granite concassé - à 14% de verre pilé - 5 à<B>2,5%</B> de silice micronisée. This mortar and the products necessary for its application (see below: implementation) are manufactured in the following manner: 1) Mortar - 70% by weight crushed granite - 14% crushed glass - 5 to <B> 2.5% </ B> of micronized silica.

Ces trois composants, solides, sont mélangés à sec, et additionné juste avant l'application de - 15 à 25 % de consolidant à base de silicate d'éthyle, liquide. These three components, solid, are dry blended, and added just before the application of - 15 to 25% of consolidant based on ethyl silicate, liquid.

2) Le mortier de même composition qu'en 1 avec un dosage précis de - à 67% en poids de granite concassé - à 12% de verre pilé - à<B>1,5%</B> de silice micronisée. 2) The mortar of the same composition as in 1 with an accurate dosage of - 67% by weight of crushed granite - 12% crushed glass - <B> 1.5% </ B> of micronized silica.

Ces trois composants, solides, sont mélangés à sec, et additionné juste avant l'application de - 21 à 23 % de consolidant à base de silicate d'éthyle, liquide. . 3) Ce mortier est mis en #uvre par petite quantité à l'aide d'une spatule. L'épaisseur peut varier de mm à 15 mm. 4) La sous couche ou couche d'accroche est composée de - à 50 % en poids de poudre de verre, - en poids de silice micronisée. These three components, solid, are dry blended, and added just before the application of - 21 to 23% of consolidant based on ethyl silicate, liquid. . 3) This mortar is used in small quantities using a spatula. The thickness can vary from mm to 15 mm. 4) The undercoat or tie layer is composed of - to 50% by weight of glass powder, - by weight of micronized silica.

Ces deux composants sont mélangés à sec, et additionné juste avant l'application de - 45 à 50 $ en poids de produit consolidant à base de silicate d'éthyle, liquide. These two components are dry blended and added just before application of - 45 to 50% by weight of liquid ethyl silicate consolidant.

5) La sous couche est appliquée au pinceau le granite à ragreer. 5) The undercoat is brushed on the granite to be roughened.

6) La couche ou couche de recouvrement provisoire est composée de - à 20% en poids de silice micronisée, - à 90% en poids d'un alcool à évaporation lente. 7) La couche est appliquée au-dessus du mortier fraî chement mis en #uvre, au pinceau. Cette couche est des- tinée à éviter la concentration du consolidant à base de silicate d'éthyle à la surface du mortier pendant la prise. Elle est retirée par simple brossage après la prise.6) The layer or temporary covering layer is composed of - 20% by weight of micronized silica, - 90% by weight of a slowly evaporating alcohol. 7) The layer is applied over the mortar freshly applied with a brush. This layer is intended to prevent the concentration of the ethyl silicate consolidant on the surface of the mortar during setting. It is removed by simply brushing after setting.
