Electrically conductive cementitious composites for marine applications
Conductive cement-based materials have attracted particular attention due to their potential to enable low-cost continuous monitoring of next-generation smart structures. This feature is relevant in highly energetic marine environments, where structural damage due to excessive loads and remote locations are critical to the performance of structures. However, to the best of the authors knowledge the literature exploring this feature in the context of marine environment is inexistent. To fill this gap, an electrically conductive cementitious composite (E3C) was developed for marine applications by introducing waste materials and fibers. Six mixtures were studied, incorporating the same matrix but varying the amount and fiber type, and water content. E3C, which conducts electricity underwater, was successfully developed, demonstrating the capacity to exhibit intelligent properties in marine environments. Self-sensing capability, assessed through electric current measurements during load application, demonstrated sensitivity to mechanical loading. This research presents promising outcomes, reshaping the paradigm of marine structures.
