The Effect of Using Raw and Epoxy Resin Coated Technical Fibers on Construction Element Performance

Abstract

Textile-reinforced concrete (TRC) is an innovative building material with areas of use such as sandwich panels, roof constructions, walking bridges and outdoor furniture, which are becoming increasingly common. TRC’s are composite structures consisting of concrete produced from fine-grained aggregate and textile structures with high tensile strength and non-corrosive. In the study, alkali resistant glass, basalt and carbon filaments, which are widely used in concrete reinforcement, were used as raw and epoxy resin coated on two different structures and in three different positions. 37 samples with different parameters were produced together with the non-reinforced sample and flexural test was applied to the samples. As a result of the flexural test, the highest value was obtained in carbon filament samples, while the lowest value was obtained in basalt filament samples. The contribution of the use of epoxy resin to the flexural strength compared to the use of raw filament was 63% in alkali resistant glass filament, 71% in basalt filament, and 127% in carbon filament.
