Influence of textile reinforced self-stressing concrete with three-dimensional collaborative textile on crack resistance and bending properties

Abstract

In order to seek highly crack-resistance building materials, textile reinforced concrete (TRC) and self-stressing concrete (SSC) have been widely studied. In the current study, it has begun to explore the addition of collaborative fibers in two-dimensional (2D) textiles to produce three-dimensional (3D) textiles to obtain better performance. In this paper, the beam specimens of three-dimensional textile reinforced self-stressing concrete (3D TRSSC) were designed and fabricated by combining 3D textile and self-stressing concrete. The improvement of crack resistance and bending performance of 3D TRSSC compared with two-dimensional textile reinforced self-stressing concrete (2D TRSSC) was explored by four-point bending test. A calculation model of 3D TRSSC based on the finite element theory and elastic mechanics method was established using MATLAB and then established to simulate the cracking load and deflection, furthermore, a method was proposed to account for the effect of collaborative fibers on the ultimate load. Results show that the theoretical calculation is in good agreement with the experimental data.
