The Usage of Carbon-Based Filament Yarns in Different Forms in the Design of Textile Reinforced Concrete Structures

Abstract

Textile reinforced concrete (TRC) is an innovative building material that has been used in recent years and consist of textile components with high tensile strength and concrete produced from finegrained aggregates. Textile components can be used in the form of raw yarn, coated with various polymers, and recently, in the form of hybrid yarn. There are many hybrid yarn production methods used in the textile industry, and in this study, the braiding technique, which is suitable for the material used, is emphasized. In the study, samples were produced by positioning two different textile surfaces produced from three different yarn structures with carbon roving in three different positions in the concrete. Compared to the raw filament use, it was observed that the flexural strength increased by 23% with the use of hybrid yarn, while it increased by 167% with the use of epoxy coated filament.
