Abstract

Mechanical and fracture behaviour of Textile Reinforced Concrete (TRC) depends on several factors such as the type of textile fibre, number of textile layers, cement matrix strength, volume fraction of fibres, mesh size, aggregate size, and most importantly the bonding between the textile fibre and the matrix. In this study, the flexural behaviour of TRC panels under monotonic loading is investigated by varying loading rates and geometrical parameters. The experiments are conducted on TRC panels containing four layers of E-glass textile fibre reinforcement under a three- point bending configuration. The effect of specimen size and rate of loading is analyzed by considering two sizes of TRC panels of dimensions 100 × 200 × 35 mm (S12) and 200 × 400 × 35 mm (S24) subjected to rates of loading of 0.5 mm/min, 1 mm/min, and 2 mm/min. Further, the Digital Image Correlation (DIC) technique is used to investigate the fracture behaviour of TRC panels. The mechanical and fracture characteristics such as load-displacement curves, first-crack load, post-peak flexural behaviour, and fracture energy are evaluated, and a comparison is drawn for TRC specimens of different geometrical sizes subjected to different rates of loading.
