Abstract

L'invention concerne un renfort en tissu destiné à renforcer une matrice cimentaire alcaline comprenant des fils de chaîne et des fils de trame. Afin d'augmenter la résistance à la traction cohésive de ses points d'intersection, le tissu présente un revêtement suffisamment résineux sur une partie substantielle des fils de chaîne et de trame, avant que le renforcement de tissu ne soit intégré à la matrice cimentaire, ou collé ou lié mécaniquement à celle-ci. Le revêtement comprend des adhésifs/polymères organiques ou inorganiques, ou le tissu présente un tissu non revêtu modifié par adhérence des brins de tissu ensemble, le sens machine et les brins perpendiculaire à la production se croisant, par exemple avec du cyanoacrylate ou de l'époxy. La force de liaison des fils d'intersection du tissu et la résistance de liaison mécanique correspondante du tissu à la matrice cimentaire peuvent également être améliorées par l'augmentation de la rugosité et/ou de la surface des fils et du tissu résultant. L'invention concerne également des procédés de fabrication de tissu, des panneaux cimentaires utilisant le tissu, et des procédés de fabrication du panneau cimentaire.
