Experimental Study on Electrical Conductivity of Carbon Fiber Reinforced Concrete Underwater

Wang, You-Zhi / Xu, Yong-Zhi / Sun, Ying

This paper studied the effect of carbon fiber dosage, concrete age, size of defect, and eater pressure on the electrical conductivity of carbon fiber reinforced concrete (CFRC). Insulating films were buried in the concrete to simulate inside cracking. The carbon fiber was added as the conductive material of the concrete. The electrical conductivity was measured with a two-electrode method with a DC power. The test results show that concrete age, defect area and the external water pressure are the main factors influencing the electrical conductivity of CFRC, while the number and location of defects have less effect.
