Characterization of Bending and Tensile Behavior of Ultra-High Performance Concrete Containing Glass Fibers
Ultra High Performance Concrete (UHPC) is used to design structural elements with unique combinations of aesthetic, lightness, self-placing and ductility properties. The difficulty to design such a ductile composite is obtaining an optimum compromise between reinforcements, cementitious matrix strengths, rheology and costs.
An ultra high performance reinforced concrete containing glass fibers (GFUHPRC) is described for thin plate geometries. Including complete mechanical characterization, based on four point bending tests, and reverse analyses to extract the post-cracking behavior in tension (e.g. the tensile strength versus strain relationship of the glass fibers). The results of accelerated aging tests in 50°C water showed that its durability and ductility were maintained.
