Electromechanical Impedance Dataset of Geopolymer Concrete under Different Mix Proportions and Curing Ages

This dataset contains electromechanical impedance (EMI) measurements of geopolymer concrete specimens with varying molarity and silica fume content. The data were collected using piezoelectric sensors to record conductance (S) and susceptance (B) responses over a frequency sweep. Measurements were performed at different curing ages (1, 3, 7, and 28 days) to capture the evolution of microstructural and mechanical properties.

The dataset includes multiple mix designs (e.g., 8M, 12M, 16M NaOH solutions with 0%, 10%, and 15% micro silica replacement) across separate Excel sheets. Each sheet provides frequency-dependent EMI signatures, which can be used for structural health monitoring (SHM), durability assessment, and predictive modeling of geopolymer concrete performance. A summary sheet is also provided for comparative analysis.

Potential Applications:

Development of EMI-based monitoring techniques for geopolymer concrete.

Understanding the effect of curing age and mix design on impedance response.

Benchmarking for machine learning models in concrete material characterization.
