Title
(EN) COMPOSITION FOR REPAIRING A CONCRETE SECTION, USING A JUTE FIBER REINFORCING MATERIAL
(FR) COMPOSITION DE RÉPARATION D'UNE SECTION DE BÉTON À L'AIDE D'UN MATÉRIAU DE RENFORCEMENT PAR LES FIBRES DE JUTE
(KO) 황마섬유 보강재를 이용한 콘크리트 단면 보수재 조성물
Abstract
(EN)
The present invention relates to a composition for repairing a concrete section, including an aggregate portion, a binder portion, and a fiber reinforcing material, wherein the fiber reinforcing material includes jute fibers with an average thickness of 65 to 75 μm and an average length of 3 to 6 mm. Using jute fibers as the fiber reinforcing material exhibits comparatively excellent dispersibility and binding force for mixing. The jute fibers also exhibit high moisture retention to maintain the hydration of the repairing composition during the curing period after placement. Thus, the problem of false setting that arises when a material for repairing a concrete section dries too quickly can be avoided.
(FR)
La présente invention concerne une composition de réparation d'une section de béton, qui comprend une partie d'agrégat, une partie de liant, et un matériau de renforcement par les fibres, le matériau de renforcement par les fibres comprenant des fibres de jute qui présentent une épaisseur moyenne de 65 à 75 μm et une longueur moyenne de 3 à 6 mm. L'utilisation de fibres de jute en tant que matériau de renforcement par les fibres présente une dispersibilité et une force de liaison comparativement excellentes pour le mélange. Les fibres de jute présentent également une haute rétention de l'humidité pour maintenir l'hydratation de la composition de réparation durant la période de durcissement après le positionnement. Ainsi, le problème de fausse prise qui se produit lorsqu'un matériau de réparation d'une section de béton sèche trop rapidement peut être évité.

본 발명은 골재부, 결합재부 및 섬유 보강재를 포함하는 콘크리트 단면 보수재 조성물에 관한 것으로서, 상기 섬유 보강재는 평균굵기가 65 내지 75 ㎛이고 평균길이가 3 내지 6 mm인 황마섬유를 포함한다. 섬유 보강재로서 사용된 황마섬유는 배합시 분산성 및 결합력이 비교적 우수하다. 또한, 황마섬유는 높은 함수율을 나타내므로 시공후 양생기간 동안 보수재 조성물의 보수성을 유지하게 한다. 이에 따라 콘크리트 단면 보수재가 급격히 건조되어 발생하는 가응결의 문제점을 방지한다.
