Direct Pore‐Scale Numerical Simulation of Microbially Induced Calcium Carbonate Precipitation
Published 2023-01-01“…We also explored effects of biomass density and biomass distribution on the reactive transport factors, as well as the effect of the urea to calcium ratio on the resulting crystallization patterns. We found that a higher ratio of rate of ureolysis to rate of precipitation leads to more nucleation sites and more uniform calcite precipitation in the geometry.…”

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. …”
