Physicochemical properties of Zr-ACP filler used in the study.

Property/method	Findings
Long-range structure (XRD)	Two diffuse broad bands in 2θ(°) = (4 to 60) region typical of ACP
Short-range structure (FTIR)	Two typical phosphate absorption bands at (1200 to 900) cm^-1 and (630 to 500) cm^-1
Morphology, size (SEM)	Heterogeneous particle sizes, predominantly agglomerates ranging from approx. 5 μm to 20 μm; some larger than 100 μm
Particle size (PSD analysis)	Particle sizes ranging from submicron to > 100 μm in diameter; average calculated median diameter, d_m = 7.4 μm
Water content (TGA)	Zr-ACP filler contained a mass fraction of (16.1 ± 2.0) % water
