Dynamic mechanical behavior of polypropylene fiber-reinforced shotcrete: Experimental analysis, microstructural observation, and numerical simulation
Published 2025-09-01“…Key findings include: (1) The material exhibits strain-rate dependency: as impact rate increases, mechanical properties, toughness index, ductility index, and energy dissipation improve, but sample integrity declines. (2) At 5.143 m/s loading rate, 0.1 % PPF dosage delivered optimal performance: 33.8 % higher compressive strength, 14.6 % greater elastic modulus, 19.5 % enhanced toughness, 42.6 % increased ductility, and 23 % improved energy dissipation ratio versus PPF-free specimens. (3) Microscopically, PPF inhibits crack propagation by forming stress-dispersing bridges within the cement matrix, improving crack resistance. …”
