Resumen

Currently the disposable materials of metallurgical companies are not used in a beneficial way, but they can be reused and used to make different fibers, the application of fibers for concrete reinforcement is being carried out in the construction sector because it reduces the environmental pollution and also causes benefits in the mechanical properties of concrete. The objective of this research is to evaluate the mechanical properties of concrete with steel fibers (SF) and plastic fibers (PF). Mechanical tests were carried out on conventional concrete, concrete with SF in proportions of 0.44, 0.88, 1.32 and 1.76% of the volume of concrete and PF in proportions of 0.04, 0.07, 0.09 and 0.11% of the volume of concrete. According to the results, the improvement of 0.44% SF with 0.04% PF improves the compressive strength; the combination of 0.44% SF plus 0.11% PF increases the flexural strength and the combination of 0.44% SF plus 0.04% PF increases the tensile strength. It is concluded that the present study demonstrates that the combination of SF with PF improved the mechanical properties of concrete.
