Fig. 20: Overview of replacement levels across different SCMs or alternative materials, grouped by the corresponding replacement type.

Replacement levels shown represent the percentage (by mass) of the specific constituent being substituted (e.g., cement, silica fume, micro-filler, or aggregate). The dataset presented here corresponds directly to the data used in the subsequent strength performance analysis (Fig. 21) to ensure consistency and coherence across this section. (Note: MT indicates mine tailings in this figure).
