Abstract

Textile reinforced ultra high performance concrete (TR-UHPC) is developed to further improve the tensile strength and ductility with reduced steel fiber contents. Alkali resistant glass textiles are used to partially replace steel fibers in a hybrid manner. The effects of different steel fiber content on the tensile and bending properties is investigated for four short fiber content levels. It is found that the synergistic effects of the hybrid reinforcements can be used to enhance of strengthening and toughening mechanisms with reduced cost. Pronounced strain hardening and deflection hardening are observed under tension and bending tests. The highest ductility of the TR-UHPC specimens are obtained when the steel fiber content is 1.0% vol with enhanced strength.
