Enhancements in Bond in Textile Reinforced Concrete: Experiments and Modeling

Yarden Rahamim, Isabel Zayas, Matthew P. Adams, Matthew J. Bandelt and Alva Peled

Abstract

Textile reinforced concrete (TRC) has been subject to intense R&D effort, as it known to improve the brittle tensile properties of the concrete. The bond between the textile bundle and the cement matrix is a crucial factor that control TRC elements performance. Unfortunately, methods to improve the bond between textile fabrics and a concrete matrix are limited. This paper evaluates techniques to improve bond in TRC systems through a multi-scale approach using experimental and numerical methods. Specifically, the pullout behavior of textile fabrics within a cementitious matrix through various treatment mechanism is evaluated. Then the direct tension response of the composite TRC systems is evaluated across treatment mechanisms. Three-dimensional nonlinear finite element models are used to simulate experimental behavior and understand how treatment mechanisms influence local pullout response, crack opening in direct tension, and strain distribution.
