The application of electrical methods to the technology of cementitious materials opens up new possibilities for monitoring setting and hardening processes of fresh, admixtured pastes or for tracking the invasion of aggressive chemicals in hardened structures. The electrical conductivity can be related, by means of percolation models, to the porosity of the material and, therefore, to its strength. Innovative formulations with unusual properties can also be produced by controlling the electrical conductivity of hardened mortars. Further, energy efficient accelerated hardening techniques and contactless breaking techniques for decontamination and decommissioning processes in nuclear power plants are being developed.
