Abstract
Under various voltages, the performance variations and compressive and flexural failure modes of carbon fiber concrete were investigated. The findings indicate that while the general concrete will display a cone upon failure, the compressive carbon fiber concrete specimen maintains its integrity under the influence of voltage, displaying a state of surface cracking with similar-sized crack spacing. With an increase in voltage level, the compressive strength of carbon fiber reinforced concrete first rises and then falls. The compressive strength of carbon fiber concrete at a voltage level of 15V is 66% higher than that of carbon fiber concrete without voltage. Similar to the flexural strength test phenomenon of uncharged carbon fiber concrete, the flexural strength test phenomenon of concrete beams when applying voltage is immediate fracture. The maximum strength of carbon fiber reinforced concrete is only 10% higher, and the flexural strength is only marginally improved, fluctuating.
