Self-sensing performance of materials represents a key issue for the development of biomimetic civil structural health monitoring systems towards smart and resilient infrastructures. During the last decades, research interest in smart cement-based composites obtained by adding conductive nanofillers to cementitious matrices has been strongly increasing, although several issues remain open. This experimental study focuses on the electromechanical properties of self-sensing cement-based composites obtained by using functionalized carbon nanotubes as fillers. Quasi-static tests were carried out on specimens subjected to pure compression. The influence of filler concentration and water-to-cement ratio was assessed. 

Keywords: smart cement-based composites; self-sensing; functionalized carbon nanotubes; structural health monitoring.
