Cement-based sensors with carbon fibers and carbon nanotubes for piezoresistive sensing
Faezeh Azhari,Nemkumar Banthia +1 more
TL;DR: In this paper, two types of cement-based sensors, one with carbon fibers alone and the other carrying a hybrid of both fibers and nanotubes, were considered and their ability to sense an applied compressive load through a measureable change in resistivity was investigated.

Electrical resistivity measurements of Portland cement based materials
TL;DR: The electrical resistivities of four different cements have been found to exhibit very different age dependencies and these differences cannot be readily explained in terms of their compositions and water/cement ratios.
Electrically conductive concrete
TL;DR: In this article, the authors discuss the manufacture of electrically conductive concrete in which conventional sand aggregates are replaced by marconite, a carbon byproduct of oil refining.
