ABSTRACT

Textile reinforced concretes use multifilament yarns as reinforcement. Their mechanical properties are mainly governed by the impregnation of the yarns by the cementitious matrix. Two experimental methods that allow the level of impregnation of the yarn to be quantified are presented. These methods were tested on five different glass yarns, for three preparation methods that induce different level of impregnation. The results are discussed and compared to qualitative characterisation obtained from scanning electronic microscopy, which allows us to link them with the impregnation.

RÉSUMÉ

Les bétons textiles utilisent comme renfort des fils multifilamentaires dont l'imprégnation par la matrice cimentaire conditionne largement les propriétés mécaniques. Deux méthodes expérimentales qui permettent de quantifier le niveau d'imprégnation du fil sont présentées ici. Ces méthodes ont été testées sur cinq types de fils multifilamentaires de verre, pour trois modes de préparation conduisant à des niveaux d'imprégnation différents. Les résultats des deux méthodes proposées sont mis en parallèle avec la caractérisation qualitative de l'interface fil/matrice réalisée par microscopie électronique à balayage, ce qui permet de faire le lien avec l'imprégnation.
