1. A method of forming an electrically conductive cement composite, the method comprising:
mixing nanoporous carbon nanoparticles in an aqueous solution of a carbon nanoparticle dispersing agent thereby creating a nanoporous carbon nanoparticle suspension;
mixing a hydraulic cement powder with the nanoporous carbon nanoparticle suspension; and
filling a portion of a capillary pore network of the electrically conductive cement composite with the nanoporous carbon nanoparticle suspension thereby creating a continuous percolating conductive network of the nanoporous carbon nanoparticles.
