description This article evaluated mechanical behavior of ultra-high performance concrete (UHPC) reinforced with hybrid steel and polypropylene fibers, with cement consumption of 250 kg/m³ and application of confining pressure in fresh state. The consistency of the mixture was analyzed, as well as mechanical properties of compressive strength, flexural strength and toughness. The percentages of hybridization were 50 to 100% of metal fibers and 0 to 50% of polypropylene fibers. Results showed that the compressive strength of the composite was 180 MPa (26100 psi), despite its low cement consumption of 250 kg/m³ (2.08 lb/gal), with 80% steel fibers and 20% polypropylene fibers. The combination of fibers increased the mixture’s toughness. For the composition with 80% steel fibers and 20% polypropylene fibers, the strength for large deformations increased by 191% compared with the mixture with 100% steel fibers, pointing out the benefits of hybridization.

Se analizó la consistencia de la mezcla, las propiedades mecánicas de las resistencias a la compresión y flexión, así como la tenacidad. Se usaron porcentajes de hibridación del 50 al 100% de fibras metálicas y de 0 al 50% de fibras de polipropileno. Los resultados muestran que la resistencia a la compresión del compuesto fue de 180 MPa (26.100 psi), a pesar de su bajo consumo de cemento, de 250 kg/m³ (2,08 lb/gal), con 80% de fibras de acero y 20% de fibras de polipropileno. La combinación de fibras incrementó la tenacidad de la mezcla.
