Dataset for 'Crack growth and closure in cementitious composites: monitoring using piezoceramic sensors'

The Data in this spreadsheet is pertinent to the study in the paper titled ' Crack growth and closure in cementitious composites: monitoring using piezoceramic sensors’. The spreadsheet contains the real part of the electrical impedance of Lead Zirconate Titanate PZT sensors, which were attached to the surface of different mortar samples. The samples are numbered Sample 1, 2, 3, 4 and 5, and the PZT are either donated PZT (C), which are close to the crack location or denoted PZT (S), which are further away from the crack location. For sample 5, only PZT (C) was monitored, therefore the data in the data set for this sample is only for PZT (C).本电子表格中的数据与题为《胶凝复合材料的裂纹扩展与闭合：基于压电陶瓷传感器的监测》的论文研究相关。该电子表格收录了附着于不同砂浆试样表面的锆钛酸铅（Lead Zirconate Titanate，PZT）传感器的电阻抗实部数据。本次研究的试样编号为试样1至试样5，所使用的PZT传感器分为两类：标记为PZT（C）的传感器靠近裂纹位置，标记为PZT（S）的传感器则远离裂纹位置。其中试样5仅监测了PZT（C），因此本数据集内该试样的数据仅对应PZT（C）。
