New functionalities of cement paste: electron conductive cement-carbon nano-composites

Cement-Nanocarbon Composites: Structural Supercapacitors for Autonomous Buildings (CEMCAP)”. The CEMCAP project aims at transforming cement into a multifunctional material by implementing electrical energy storage and heat insulation functionalities. The ultimate goal is energetically autonomous buildings by turning concrete elements of a building into structural super-capacitor. 

This project is supported financially by the CNRS Momentum research grant

Dispersing nanoporous carbon (blue particles) in the connected pore network of cement nano-grains (gray particles), turns cement paste electron-conductive. With the addition of electrolyte and a separator the system turns into a capacitor and stores energy.
