conductive concrete, multifunctionality, piezoresistivity, heating and defrosting, shieldingAbstract
This article presents the foundations and evolution of research into the main functionalities developed using conductive cementitious materials. Multifunctional conductive concrete represents an innovation in the field of cement-based materials, exhibiting not only structural capabilities but also electrical, thermal, and sensing functions. The addressed functions are: a) strain and structural damage sensing in a load bearing structure without the need for any attached or embedded sensor; b) heating and de-icing function through the Joule effect, for applications such as surface de-icing or building heating; and c) electromagnetic interference (EMI) shielding provided by the conductive structure itself.
