The fractal characteristics of cement-based materials with grinding aid via BSE image analysis.

∆ α demonstrated excellent variance homogeneity ( p = 0.9258) with marginally significant group differences ( p = 0.0591).

For the parameter ∆ α , variance homogeneity was strongly supported (Levene’s test, p = 0.9927), the Kruskal-Wallis test ( p = 0.0842) similarly demonstrated borderline significance, mirroring the ∆ D q pattern.

11 , for the parameter ∆ D q , Levene’s test ( p = 0.9847) confirmed excellent variance homogeneity across all experimental groups, the Kruskal-Wallis test ( p = 0.0816) approached but did not reach conventional significance ( α = 0.05), while showing marginal significance at α = 0.10.
