Resistivity Prediction Model for Basalt–Polypropylene Fiber-Reinforced Concrete

As a new cement-matrix composite material, fiber-reinforced concrete performs excellently in freeze–thaw resistance, tensile and seepage resistance. Since resistivity can be used to evaluate the performance of concrete, basalt–polypropylene (BPFRC) was investigated this study. Various parameters such as fiber type, content, water–binder ratio were also analyzed. The BPFRC tested by an improved two-electrode alternating current (AC) method, differences analyzed using scanning electron microscopy (SEM) mercury intrusion porosimetry (MIP). results showed that adding affected BPFRC, basalt had more significant effect than polypropylene fiber. sensitive ratio, which negative correlation. In addition, 365-day model for established considering variables fiber, ambient temperature, relative humidity. hydration equations various cementitious materials derived, time-varying developed. Finally, lays foundation further building relationship between performance.
