Abstract
A novel cement-sand based piezoelectric smart composite was developed for structural health monitoring (SHM) in civil infrastructures. Most researches have focused on cement-based piezoelectric composites that are unrealistic in their applications due to their incompatibility with reinforced concrete with cement and sand. In this study, sand was applied to fabricate the composite to address the important issue. Two sets of specimens containing 30 vol% and 50 vol% lead zirconate titanate (PZT) were manufactured and their piezoelectric coefficient and dielectric constant were determined. The results showed that the piezoelectric effect and dielectric constant were enhanced with increasing PZT content. In addition, the sensing effect was conducted under compressive tests. The invesitigation demonstrated the feasibility of the new composite in its application to the SHM system.
