The parameters used, their best relationships
with A and B, and corresponding correlation coefficients
are given in Table 4. As seen from the table, fair
correlations between the constants and Al2O3, free CaO
contents, silica modulus (SM), liquid phase (Lp), and ratio
of silicates to fluxes [(C3S
1 C2S)/C3A
1 C4AF)] exist.
