A process involves adding charged fibers with surface-cured "temperature-sensitive gel" during the preparation of concrete; preparing charged fibers with surface-cured "temperature-sensitive gel" by spraying, which envelops the charged fibers with a layer of "temperature-sensitive gel"; then solidifying the temperature-sensitive gel layer on the surface of the charged fibers by adjusting the environmental temperature. Utilizing the physical state of the temperature-sensitive gel at different temperatures, the "temperature-sensitive gel" wraps around the charged fibers to form an insulating layer. This prevents the scattering of the charged fibers due to charge repulsion during their introduction into the concrete preparation process, ensuring they are evenly distributed.
