Description

Béton UR SOCOTRASConcrete UR SOCOTRAS

La présente invention concerne une formulation de béton de revêtement aéronautique circulable par les aéronefs 2 heures après sa mise en œuvreThe present invention relates to an aeronautical coating concrete formulation that can be traveled by aircraft 2 hours after its implementation.

Dans le domaine aéronautique, l’Aviation Civil préconise une résistance minimale de 3.3 MPa à l’essai de traction par fendage sur éprouvette 15 mm x 30mm (selon la norme NF EN 12390-6) pour pouvoir ouvrir la circulation aux avions sur les voies et sur les aires de stationnement en béton neuf.In the aeronautical field, the Civil Aviation recommends a minimum resistance of 3.3 MPa to the tensile test by splitting on a 15 mm x 30 mm specimen (according to standard NF EN 12390-6) to be able to open traffic to aircraft on the tracks. and on new concrete parking areas.

Le béton de revêtement aéronautique classique est formulé uniquement avec des ciments PORTLAND purs. Les formulations classiques de béton de revêtement aéronautique atteignent une résistance, en traction par fendage, égale à 3.3 MPa, après un délai de cure de 28 jours. Ce délai implique de fortes contraintes pour l’exploitation des plateformes aérienne, notamment dans le cadre des travaux d’entretien des dallages endommagés (fermeture longue des voies de circulation avion ou des aires de stationnement occasionnant une gêne au trafic).Classic Aircraft Coating Concrete is formulated with only pure PORTLAND cements. Conventional formulations of concrete for aeronautical coating achieve a resistance, in tension by splitting, equal to 3.3 MPa, after a curing period of 28 days. This delay entails strong constraints for the operation of aerial platforms, particularly in the context of maintenance work on damaged paving (long closure of aircraft taxiways or parking areas causing traffic disruption).

La formulation de béton selon l’invention permet d’atteindre une résistance en traction par fendage supérieur à 3.3 MPa, après un délai de cure de 2h (2h après la mise en œuvre du béton), limitant ainsi la gêne occasionnée à l’exploitation.The concrete formulation according to the invention makes it possible to achieve a tensile strength by splitting greater than 3.3 MPa, after a curing period of 2 hours (2 hours after the implementation of the concrete), thus limiting the inconvenience caused to operation. .

Le béton UR SOCOTRAS est formulé avec un ciment hybride composé d’un alliage de ciments sulfo-alumineux (CSA) et de ciment portland (de type CEM I ou CEM II). Ce ciment hybride a pour spécificité d’avoir un temps de prise beaucoup plus court, une meilleure résistance à court terme, un retrait très faible et une meilleure durabilité comparée au ciment Portland traditionnel.UR SOCOTRAS concrete is formulated with a hybrid cement composed of an alloy of sulpho-aluminous cements (CSA) and Portland cement (CEM I or CEM II type). This hybrid cement has the specificity of having a much shorter setting time, better short-term strength, very low shrinkage and better durability compared to traditional Portland cement.

La formulation de béton selon l’invention permet une réouverture quasi immédiate au trafic avion, 2 heures après coulage, avec un béton répondant à l’ensemble des préconisations techniques requises pour le béton revêtement aéronautique sur les aéroports nationaux et internationaux de France.The concrete formulation according to the invention allows an almost immediate reopening to aircraft traffic, 2 hours after pouring, with a concrete that meets all the technical recommendations required for aeronautical coating concrete at national and international airports in France.
