Dataset for "Insights into the piezoceramic electromechanical impedance response for monitoring cement mortars during water saturation curing"

Data collection method:

For ‘Analysis PZT_EMI Data.xlsx’, A 2 V voltage amplitude was used to actuate the PZT sensors, by a Newtons4th PSM 3750 frequency analyzer (Newtons4th Ltd., Leicester, UK) interfaced with an impedance analyzer. The impedance analyzer and the PZT sensors were connected through 50 Ω coaxial cables; specifically, the cables connected to the impedance analyzer at one end and to the PZT soldered wires at the other. For ‘Flexural and compressive.xlsx’, A 100 kN Instron static testing frame was used for both the flexural and compressive stress measurements.

Technical details and requirements:

The spreadsheets are in MS Excel format.

Additional information:

The dataset is composed of two Excel files. ‘Analysis PZT_EMI Data.xlsx’ is composed of nine separate sheets. These sheets are named as Ci-j, in which i is the mortar mix number, and j is the sample number. The values of i and j range from 1 to 3. Each sheet contains the impedance signature measurements for each sample from the age of 2 days till the age of 28 days. The impedance signature was collected by using a Newtons4th PSM 3750 frequency analyzer (Newtons4th Ltd., Leicester, UK) interfaced with an impedance analyzer. One thousand steps were collected per measurement as mentioned in the methodology in the associated paper. The columns of each sheet show Step, Frequency (Hz), Z Real (ohms), Z Quadrature (ohms), Z Magnitude (ohms), Z Phase (°). ‘Flexural and compressive.xlsx’ contains the average flexural and the compressive stresses for the different mixes at the ages of 3, 7, 14, 21, and 28 days. Sheet 1, which is named ‘Compressive strength’, contains the compressive strength data, and sheet 2, named ‘Flexural strength’, contains the Flexural strength data.
