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).
