Análisis comparativo del hormigón tradicional con hormigón elaborado con fibras de caucho reciclado incorporado a volúmenes de 0.50%, 0.75%, 1.00% y 1.25%, mediante los ensayos a compresión y tracción

Abstract

This article presents the comparison between traditional concrete and concrete with recycled rubber fibers incorporated in light volumes as fine aggregate. Following the ASTM and INEN procedures and regulations for the correct characterization of materials and components to obtain suitable results for a resistance of 24MPa, being evaluated through compression and indirect traction tests. By incorporating rubber fibers as a recyclable material, the aim is to reduce the waste generated in civil construction and incorporate new construction techniques and methods, for which purpose mixtures were made at different percentages and compared with traditional concrete, with which favorable results were obtained. Thus, being a traditional concrete of 22.48 MPa at 7 days and 28.85 MPa at 14 days of their respective tests, while in its maximum percentage of rubber inclusion; that is, from 1.25%, a resistance of 18.34 MPa was obtained at 7 days and 24.33 MPa at 14 days of their respective tests. On the other hand, in indirect tensile tests, they present values of up to 3.88 MPa in traditional concrete and 2.95 MPa in concrete with the incorporation of 1.25% recycled rubber fibers 14 days after the test.
