Infrastructures. Ouvrages en terres. Fondations. Tunnels. Ponts et charpentes Résumé : 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.
