Abstract: Electrically conductible concrete formed by adding shortly cut carbon fiber into common concrete was tested for conductivity and mechanical properties in triaxial compression under the actions of one-time and cyclic loading by direct current measurement. It shows that the changes in electrical resistance and load are synchronous. Compared with carbon fiber reinforced concrete in mono axial compression, the trend of electrical-mechanical relations is similar, i. e., the resistance goes down as the load up, and the resistance goes up as the load down. The difference is that the change rate of resistance is larger in triaxial compression than that in mono axial compression under the action of one-time or cyclic loading. Also, the changing range of resistance is more stable in triaxial compression than that in mono axial compression.
