Electrical properties of carbon nanotubes filled cementitious composites

Twelve types of multi-walled carbon nanotubes (MWCNTs) at contents of 0.1%, 0.5% and 0.8% were incorporated into cementitious composites. A new method to calculate the electrical resistivity of these composites was proposed. The effects of MWCNT types and contents on electrical resistivity and electrochemical impedance spectroscopy (EIS) of cementitious composites were investigated. The equivalent circuit model of cementitious composites with...
