Title: Experimental Assessment and Micromechanical Interpretation of
MWCNT-Based Self-Sensing Cementitious Composites
Abstarct: The development of self-sensing cementitious composites offers a promising solution for the
continuous Structural Health Monitoring (SHM) of civil infrastructure. By incorporating
electrically conductive nanofillers, cement-based materials can act as intrinsic sensors,
overcoming some of the durability, compatibility, and spatial-coverage limitations associated
with externally installed monitoring devices. Among the available conductive fillers, multi-
walled carbon nanotubes (MWCNTs) are particularly attractive because they can form
electrically conductive networks whose configuration changes under mechanical loading.
However, the sensing reliability of these composites strongly depends on nanotube
concentration and dispersion within the cementitious matrix.
