Cement‐Based 0‐3 Piezoelectric Composites

To meet the requirements of development for smart or intelligent structures in civil engineering, new functional materials that have good compatibility with civil engineering structural materials are needed. In this study, for the first time in the field of piezoelectric materials, cement‐based 0‐3 piezoelectric (PZT) composites were fabricated by the normal mixing and spreading method. The new materials have very good compatibility with portland cement concrete. The cement‐based 0‐3 piezoelectric composites were shown to have a slightly higher piezoelectric factor and electromechanical coefficient than those of 0‐3 PZT/polymer composites with a similar content of PZT particles; thus, they are adequate for sensor application. There is potential for the application of cement‐based 0‐3 PZT composites in civil engineering because of their better piezoelectric properties and good compatibility with portland cement concrete.
