Expansive and mechanical properties of textile reinforced self-stressing concrete

Abstract

To improve the crack resistance of concrete, textile-reinforced self-stressing concrete was prepared by combining self-stressing concrete and textile. The confinement effect of textile on the concrete matrix allows for the establishment of self-stresses in the matrix, which can highly enhance crack resistance. In this research, expansion deformations of self-stressing concrete under unconfined and confined conditions were measured. Furthermore, co-workability between self-stressing concrete matrix and textile was evaluated through pull-out and compressive experiments. Finally, section analysis method was used to analyze the anti-crack performance and flexural behavior of textile-reinforced self-stressing concrete. The textile and self-stressing concrete are found to work well together, and textile-reinforced self-stressing concrete can largely improve the crack resistance of concrete materials.
