The percolation process and its equivalent circuit of cement-based conductive composites are theoretically analyzed. The characteristics of conductive materials when the content reaches the lower threshold are obtained. A new method to determine the lower threshold of cement-based conductive materials is proposed. Carbon fiber reinforced cement and graphite conductive cement were verified and found that this new method can easily and accurately determine the lower threshold of cement-based conductive composites
