Nanocarbon Cement for Heating and Storage
A collaborative effort of MIT researchers and the French National Center for Scientific Research has helped create novel functionalities for cement such as electron conductivity. This would enable the use of concrete for a variety of new applications ranging from self-heating to energy storage.. Cement has so far being used as a structural material. Electron conductivity was made possible by the controlled introduction of highly conductive nanocarbon materials into the cement mixture. When nanocarbon black, a cheap carbon material with excellent conductivity was introduced, cement was transformed from a insulator to a conduct. By incorporating nanocarbon black at just a 4% volume of cement mixtures, the percolation threshold was reached, the point at which their samples could carry a current. Heat could also be generated due to Joule’s effect.
