- •
Granular plasticity was assessed from compression analysis.
- •
The granule plasticity could not be differentiated with global Heckel numbers.
- •
The voidage Heckel profiles captured the plastic differences to a higher extent.
- •
The voidage was thus considered as a better descriptor of the reactant pore system.
- •
Plastic differentiation was enabled using Kawakita and Adams parameters.
