The 7-day compressive strength model shows marginal significance ( P = 0.079), suggesting a comparatively weaker influence of the selected factors at early ages.

Among interaction terms, AC (FA × w/b) is highly significant, confirming the synergistic effect between FA morphology and water availability in improving flow.
