Tensile identification of textile reinforcement concrete behaviour
Textile reinforced concrete shows a complex mechanical behaviour, which arises from the heterogeneity of the cementitious matrix and the reinforcement yarn, as well as different bond conditions inside the yarns. This contribution aims to analyze the textile reinforced concrete tensile (TRC) behaviour. Firstly, a tensile test suitable for this type of cracking material is designed and validated. The second phase aims to highlights the influence of several parameters considered as critical (the material, the thickness of the composite, the impregnation of the fibres, the fibre volume ratio) in the textile reinforced concrete (TRC) behaviour in terms of mechanical performance (strength and stiffness) or the amount of damage correlated with the crack opening measured using image correlation analysis. The final section is to assess on the basis of these results, the validity of analytical models proposed and, if necessary, propose some modifications.
