Construction and Building Materials 2025
Specimens with 20% metakaolin and 2.5% paraffin exhibit the highest electrical resistivity
Optimal resting time around 3 hours
Electrical resistivity decreases as heating rate increases
60°C most suitable for maintaining stable curing environment
Extended thermostatic time further enhances resistivity
Metakaolin content strongest correlation with resistivity (0.82)
Heating time weakest correlation (0.59)
