Abstract Piezoelectric ceramic – Portland cement composites have been developed for sensor application in concrete structures to overcome the acoustic matching problem that may occur for piezoelectric ceramic or polymers with concrete. Pozzolanic materials such as fly ash are commonly used in concrete to enhance durability. The objectives of this research were to investigate the effects of fly ash addition on the physical properties, dielectric properties and piezoelectric properties of 0–3 barium zirconate titanate ceramic– Portland cement composites. The results showed that the dielectric constant of these composites decreased when the fly ash content in the composite increases. However , the piezoelectric coefficient (d 33 ) value of BZT–PC composite with fly ash 10% by volume was found to be similar to that of BZT–PC composites.

0-3 无铅锆钛酸钡陶瓷-波特兰粉煤灰水泥复合材料的显微结构、介电和压电性能

摘要 压电陶瓷 - 波特兰水泥复合材料已被开发用于混凝土结构中的传感器应用，以克服压电陶瓷或聚合物与混凝土可能出现的声学匹配问题。火山灰材料如粉煤灰通常用于混凝土以提高耐久性。本研究的目的是研究粉煤灰的添加对 0-3 锆钛酸钡陶瓷-波特兰水泥复合材料的物理性能、介电性能和压电性能的影响。结果表明，随着复合材料中粉煤灰含量的增加，这些复合材料的介电常数降低。然而，发现粉煤灰含量为 10% 的 BZT-PC 复合材料的压电系数 (d 33 ) 值与 BZT-PC 复合材料的相似。
