Abstract

A nanoporous carbon-loaded cement composite that conducts electricity. The nanoporous carbon-loaded cement composite can be used in a variety of different fields of use, including, for example, a structural super-capacitor as an energy solution for autonomous housing and other buildings, a heated cement for pavement deicing or house basement insulation against capillary rise, a protection of concrete against freeze-thaw (FT) or alkali silica reaction (ASR) or other crystallization degradation processes, and as a conductive cable, wire or concrete trace.
