採用拌製及壓製將鋯鈦酸鉛 (PZT) 和水泥製成0-3 型水泥基壓電複合材料，實驗結果顯示，材料經65C 養護溫度的壓電效應比22C 養護溫度明顯，在20 到 60 PZT 的壓製材料與在30到50PZT 的拌製材料都能完成極化程序和獲得壓電特性，只要1.0 kV/mm 極化電壓及20 分鐘極化時間就能使20PZT 壓製試體產生壓電性質，要成功極化50PZT 壓製材料的極化電壓不可超過1.75 kV/mm。壓製試體的壓電應變常數、機電耦合常數、相對介電常數和電容都會隨著PZT 含量增加而增加，但在40到50PZT 含量的壓電應變常數及機電耦合常數會趨近於平穩。拌製材料在30到50PZT 含量的壓電性質比壓製材料好，然而壓製材料的製程和極化過程比較穩定，壓電性質的變異性較小。若要提高0-3 型水泥基壓電複合材料的極化成功率和壓電性質，可朝向降低拌製材料的孔隙和增加壓製材料整體膠結性來改良。

In this paper, we study the piezoelectricity of 0-3 cement-based PZT composites. The composite specimens are produced by combining PZT powders and cement binders through blending or pressure approaches. Our results show that the piezoelectricity of PZT/cement composites is more prominent for specimens cured at high temperature (65C) than at low (22C). The results also indicate that the PZT/cement composites could successfully obtain their piezoelectricity after polarization for specimens containing 20 to 60 PZT formed by pressure, and specimens containing 30 to 50
PZT via blending, respectively. For pressure specimens, a poling voltage of 1.0 kV/mm over 20 minutes can easily trigger the piezoelectricity of 20PZT/cement composites, while the maximum poling voltage should not exceed 1.75 kV/mm for 50 PZT/cement composites. The corresponding piezoelectric properties such as piezoelectric strain constants, electromechanical coupling factors,dielectric constants, and electric capacity would increase with the PZT contents. In particular, the piezoelectric strain constants and electromechanical coupling factors would reach a plateau when the PZT contents are between 40 and 50. The overall piezoelectric properties of blending specimens behave better than those of pressure specimens; however, the manufacturing and polarization processes of pressure specimens are much stable, leading to fewer variants of the electric measurements. We also suggest that in order to improve the piezoelectric properties of 0-3 PZT/cement composites, lowering the porosity of blending composites and enhancing the material bonding of pressure composites are both required.
