A Review on Textile Products for Reinforcing Concrete Sandwich Panels

Abstract

Concrete sandwich panels have gained considerable popularity in the construction industry. Based on their structural and thermal performance, sandwich panels have been employed in industrial, residential, and commercial structures. Two concrete outer layers are connected by connections that run through the interior insulating material, which is isolated from the exterior layers by an insulating stiff foam core to increase thermal effectiveness. There are numerous issues with the steel used for reinforcement including corrosion, high cost, heavy weight, increased thickness, and thermal bridges. Textile reinforcing concrete (TRC) is a solution for these issues, for that; researchers have attempted to replace steel with various textile goods to improve the quality of sandwich panels. Many researchers used textile’ grides for enhancing sandwich panels’ thermal isolation and reinforcing properties as nets or as a connector. This article reviews and observes methods of reinforcing concrete sandwich panels with TRC with different materials, constructions, behavior and application of textiles for investigating sandwich panels’ performance as well as textile reinforcing of concrete and discussing differences between these applications. It was found that TRC can be used for reinforcing concrete sandwich panels as core, as grid or as a connector, All these shapes of TRC effect on the performance of concrete sandwich panels positively.
