Abstract

The concrete is obtained with a mixture essentially composed of water andcement with the addition of rubber particles. The rubber particles areadvantageously obtained from the recycling of shredded tyres and are between5 and 30 mm in size. The concrete according to the invention may be used insoundproofing screens, non-vibrating slabs, machine frames, etc.

Description

       

   <Desc/Clms Page number 1> 
 



  DESCRIPTION Nouvelle composition de béton. 



   La présente invention concerne une nouvelle composition de béton et en particulier une composition comprenant le mélange de béton avec des particules de caoutchouc. 



   Pour obtenir une absorption acoustique ou vibratoire d'éléments en béton on a déjà proposé d'utiliser une composition de béton à base de boules d'argile expansées. 



   Toutefois l'amortissement du son et des vibrations par des éléments en béton fabriqués à base de boules d'argile expansées n'est pas satisfaisante. 



   Afin d'accroître cet amortissement dans des éléments en béton la présente invention propose une nouvelle composition de béton présentant des caractéristiques d'élasticité et des qualités antivibratoires souhaitées dans de nombreuses applications. 



   A cet effet la nouvelle composition de béton, objet de la présente invention comprend les éléments tels que décrits dans la revendication 1. 



   Afin de bien faire comprendre l'invention, on décrira ciaprès un exemples de réalisation pratique. 



   La composition dépend essentiellement du genre d'application des éléments en béton. 



   On distingue deux groupes de compositions différentes et notamment le béton léger et le béton compact. 

 <Desc/Clms Page number 2> 

 



   Un exemple de composition de béton léger selon l'invention comprend, pour l'obtention de 1 m3 de béton : . 100 à 200 kg de ciment ; . 50 à 100 litres d'eau ; . entre 1 et 2 m3 de particules de caoutchouc de 5 à 30 mm issues du broyage de vieux pneus restées intimement mélangées à des fibres d'acier et de Nylon. 



   On obtient ainsi un mètre cube de béton léger présentant des caractéristiques excellents d'absorption phonique utilisables dans des applications telles que : écrans antibruit insensibles aux intempéries pour chemin de fer, les trains à grande vitesse, les convois routiers, l'isolation phonique industrielle, etc... 



   Sur chantier cette composition est également intéressante pour la réalisation de dalles antivibratoires sous convois routiers ou ferroviaire, sous bâti de machine et l'enduisage des soubassements de bâtiments à proximité de voiries pour réduire soit à la source, soit à la réception, la nuisance des vibrations transmises par les solides. 



   En général on peut citer comme avantages de la nouvelle composition de béton selon   l'invention :   . caractéristiques d'élasticité ; . qualités anti-vibratoire et/ou antibruit très intéressantes ;   . légèreté,   porosité et gonflant pour des qualités d'isolation phoniques et thermiques ; . grande économie des matières premières vu la récupération de matière écologiquement nuisible telle que les vieux pneus. 



   Il va de soit que d'autres compositions de béton sont possibles, notamment sans fibres, basées sur celles citées dans la description et les revendications, sans pour autant sortir du domaine de protection conféré par la présente invention. 



   On pourrait ainsi concevoir des adjuvants pour améliorer les caractéristiques du béton ou des pigments pour obtenir une coloration éventuelle.

  DESCRIPTION New concrete composition.



   The present invention relates to a new concrete composition and in particular to a composition comprising mixing concrete with rubber particles.



   To obtain acoustic or vibratory absorption of concrete elements, it has already been proposed to use a concrete composition based on expanded clay balls.



   However, the damping of sound and vibrations by concrete elements made from expanded clay balls is not satisfactory.



   In order to increase this damping in concrete elements, the present invention provides a new concrete composition having elasticity characteristics and anti-vibration qualities desired in many applications.



   To this end, the new concrete composition, object of the present invention comprises the elements as described in claim 1.



   In order to clearly understand the invention, a practical embodiment will be described below.



   The composition essentially depends on the type of application of the concrete elements.



   There are two groups of different compositions, notably light concrete and compact concrete.

 <Desc / Clms Page number 2>

 



   An example of a composition of light concrete according to the invention comprises, for obtaining 1 m3 of concrete:. 100 to 200 kg of cement; . 50 to 100 liters of water; . between 1 and 2 m3 of rubber particles of 5 to 30 mm from the grinding of old tires which have remained intimately mixed with steel and nylon fibers.



   A cubic meter of light concrete is thus obtained having excellent sound absorption characteristics usable in applications such as: noise-insensitive screens for bad weather for railways, high-speed trains, road convoys, industrial sound insulation, etc ...



   On site, this composition is also advantageous for the production of anti-vibration slabs in road or rail convoys, under machine frames and the coating of the bases of buildings near roads to reduce either the source or the reception, the nuisance of vibrations transmitted by solids.



   In general, the advantages of the new concrete composition according to the invention can be cited: elasticity characteristics; . very interesting anti-vibration and / or anti-noise qualities; . lightness, porosity and swelling for sound and thermal insulation qualities; . great savings in raw materials given the recovery of environmentally harmful material such as old tires.



   It goes without saying that other concrete compositions are possible, in particular without fibers, based on those mentioned in the description and the claims, without however departing from the field of protection conferred by the present invention.



   It would thus be possible to design additives to improve the characteristics of the concrete or of the pigments in order to obtain a possible coloring.
