A Numerical Simulation of Electrical Resistivity of Fiber-Reinforced Composites, Part 1: Brittle Cementitious Concrete

The durability of concrete has a significant influence on the sustainability and resilience various infrastructures, including buildings, bridges, roadways, dams, other applications. Penetration corrosive agents intensified by exposure to freeze-thaw cycles presence early-age cracks is common cause reinforced degradation. Electrical resistivity vital physical property cementitious composites assess remained service life members subjected ions attacks. application steel fibers reduces vulnerability limiting crack propagation, but complicates field laboratory testing due random distribution conductive within body concrete. Numerical simulations facilitate proper modeling such improve reliability measures. Hence, this paper investigates fiber reinforcement characteristics electrical using multi-physics finite element models. Results examine challenges include insights sensitivity measures reinforcement. Concluding remarks provide expected bias in endeavor development practical guidelines for assessing fiber-reinforced standard procedures.
