Electrical Characteristics of Ultra-High-Performance Concrete Containing Carbon-Based Materials

Recently, carbon materials with unique properties, such as high tensile strength and electrical conductivity, have been extensively investigated for the multi-functionalization of concrete. Previous studies mainly focused on improving performance normal-strength concrete using nanomaterials, nanotubes graphene nanoplates. Therefore, this study analyzed effect ultra-high-performance (UHPC) mixed steel fibers, which has an outstanding mechanical performance. In addition, length effects were fibers nanometer, micrometer, millimeter sizes. The influences 120 MPa UHPC investigated, including expanded graphite, a well-known superior conductivity material. Electrical compressive strength, experimentally. As result, tends to decrease concentrations increase, chopped fiber best at 10.5 in terms strength. Since was observed be significantly higher than that other 6.6 times, millimeter-sized would most suitable material This could guide future research carbon-based materials, performances.
