Abstract

 This paper describes our study of conductive concrete, the conductivity of which is achieved through the introduction of a carbon fiber stabilized by an inorganic surfactant in a concentration of 0.12w.%. Research methods are: infrared spectroscopy, optical microscopy and conductivity measurement. Carbon fiber and its surface structure were investigated by infrared spectroscopy; based on the obtained results inorganic surface-active substance was selected. The electrical characteristics of the material were investigated. It is shown that the conductivity exhibits percolation-type behavior. There is an irreversible increase in electrical conductivity when a current of about 250 mA/cm2 and more is passed.Possible mechanisms of this phenomenon are discussed.


Keywords: conductive concrete, carbon fiber, percolation, infrared spectrum
