Study on the mechanism of the electrical conductivity of infiltrated steel fiber concrete

The property and mechanism of the electrical conductivity of Graphite slurry infiltrated steel fiber concrete(GSIFCON) are investigated.The effects of different Graphite contents on the slurry fluidity and mechanical behavior of GSIFCON are studied experimentally,and the optimum content of Graphite addition is selected.The resistivity variations of GSIFCON using both DC and AC power are tested.The results indicate that the contents of Graphite affect the resistivity of GSIFCON,and have clear percolation threshold values.Based on the analysis on the resistivity variations of SIFCON(slurry infiltrated steel fiber concrete) and GSIFCON,a conductive mechanism model of GSIFCON is proposed.
