| Sumario: | [EN] An Ultra High Performance Fibre Glass Reinforced Concrete has been developed in order to see the addition of Glass fibers in the matrix of UHPC and analyze their effects. The UHPC offers great advantages in strength, durability and surface finish. The addition of glass fibers is to improve the properties of UHPC. For decades the concrete has evolved from traditional concrete, fiber concrete, Self-Compacting concrete and high performance concrete to become what is now known as Ultra High Resistance Concrete (HMAR) or Ultra High Performance Concrete (UHPC). Has developed an experimental investigation incorporating different types of fibers and with the objective of the glass fibers and taking as reference steel fibers. There have been more than fifty 300X150X20mm specimens which have been subjected to tensile bending tests with bending 4-point method. The experimental program was composed of two blocks in which different properties of samples with UHPRFC both fresh and hardened state were analyzed. The results showed that the Ultra High Performance Fibers Reinforced Concrete (UHPRFC) increases its performance by incorporating fibers. Glass fibers increase the strength and ductility of UHPC without changing the workability of the dough whereby a Self-Compacting concrete behavior remains. Moreover the durability of the glass fibers has been affected over time but still offered better performance than the UHPC without fibers. Steel fibers and synthetic fibers showed improved, first steel fibers consumption rose from very high so the strength and ductility of the samples even surpassing the samples with glass fibers, however synthetic looked more relegated all properties analyzed. |
