Abstract
This paper presented a comprehensive experimental study on the shear capacity of zero-slump, dry-cast synthetic fiber-reinforced concrete (SYN-FRC) by using Japan Society of Civil Engineers (JSCE) G-553 test method. In adjacent with shear test, flexural and compression behavior of concrete determined based on ASTM C1609/C1609M-12 and ASTM C39/C39M-16b, respectively. In order to investigate the effect of different concrete compressive strengths on material properties of synthetic fiber-reinforced concrete, two different compressive strengths, 28 MPa (4000 psi) and 34 MPa (5000 psi), were selected. The test results demonstrated that the application of synthetic fibers in concrete yielded to significant improvements in material properties of concrete such as shear strength, shear toughness, flexural strength and flexural toughness. These enhancements were greater at higher synthetic fiber dosage rates.
