Abstract
The use of non-corrosive high-strength fibrous materials as textile reinforcement allows the construction of more slender elements when compared to members with conventional steel reinforcing bars. This paper explores the load-deformation behaviour of weft-knitted textile reinforcement embedded in a fine grain concrete. In this experimental study, flat concrete specimens with a thickness of 12-16 mm are loaded in uniaxial tension. The study focuses on the comparison of various knitting patterns, materials and geometric features in the knitted textile. Results show that the post-cracking behaviour can be improved for certain configurations in terms of ultimate strength and deformation capacity. The failure mode is governed by the material of the fibres and their coating.
