Investigations on the influence of matrix and textile on the response of textile reinforced concrete slabs under impact loading

摘要

Textile Reinforced Concrete (TRC) is gaining its popularity as a construction material. It is essential to investigate new materials to quantify its expected structural performance and integrity. The purposed study is to investigate the influence of material type and volume fraction of textile and type of matrix on the impact behaviour of textile reinforced concrete slabs. Both glass and basalt textiles were used in the investigations. Based on the investigations, it is concluded that the type of binder influences the impact resistance at first crack as well as the delamination possibility. Glass textile reinforced concrete slabs show more displacement and more residual capacity compared to basalt textile reinforced concrete slabs. With increased number of layers, the basalt textile reinforced concrete slabs exhibited decrease in impact resistance due to delamination. As energy level increases, glass textile reinforced slabs show increase in peak displacement whereas basalt textile reinforced concrete slabs show a decrease. The investigations reported will be useful for extending the knowledge of textile reinforced concrete for various impact resistant applications.
