Table 9 Quantitative TEM metrics for hydrated Lime.
Parameter | Mean ± SD | Units | Interpretation |
|---|---|---|---|
Crystal diameter (D₅₀) | 0.37 ± 0.08 | µm | Fine plate-like portlandite |
Microporosity | 21.8 ± 1.3 | % | High reactive surface area |
Phase-area fraction (portlandite) | 0.78 ± 0.04 | – | Dominant Ca(OH)₂ phase |
Ca (wt %) from EDS | 96.8 ± 1.2 | % | Confirms high purity |
Ca²⁺ concentration (leachate) | 0.012 ± 0.001 | mol L⁻¹ | Rapid dissolution and ion release |
