A state-of-the art review of tensile behavior of the textile-reinforced concrete composite

Abstract

Over the past two decades, textile-reinforced concrete (TRC) materials have been increasingly and widely used for the strengthening/reinforcement of civil engineering works. Thanks to their many advantages as the durability, considerable bond strength with the reinforced concrete (RC) members, best recycling conditions, the TRC materials are considered as an optimal alternative solution to substitute the traditional strengthening and reinforcing materials FRP (Fiber-Reinforced Polymer). The mechanical behavior of TRC composite has been characterized in previous experimental studies. This paper presents a state-of-the-art review of the mechanical behavior of TRC composite under tensile loading. By inheriting from previous review studies, this paper updates the experimental studies on the tensile behavior of TRC composite in the last decade. The review addresses, firstly the mechanical properties of constituent materials in TRC as reinforcement textile, cementitious matrix, and textile/matrix interface. Secondly, it addresses the tensile behavior of TRC composite, including the characterization methods as well as analyses of its strain-hardening behavior with different phases. The paper then discusses the main factors which influence the mechanical behavior of TRC materials in the available experimental studies. Finally, the conclusion of this review terminates this paper.
