Bogue’s formulae

According to Taylor [218] Bogue s formitlae give to low values in the case of alite and tricalcium aluminate, too high for belite and relatively correct for ferrite phases. More close to reahty results can be obtained with modified by Taylor [218] Bogue s formulae, which take into account the presence of minor components solid solutions in clinker phases. Taylor simplifying assumed that in clinker phases the quantity of minor components are on the level given in Table 2.17. 

The Bogue formula is used in order to evaluate the clinker silicate constituents starting from the clinker chemical analysis (where C, S, A, F are the relative oxides). The clinker mineralogic composition is displayed in Table 31.28. 

Ono (1995) presented a series of correction factors in the calculation of phase percentages by the Bogue equations. The factors involve minor components,solid solution of CjS and C S, solid solution of C A F-C AF, and glass. Taylor (1990) also provided formulas for correcting the Bogue calculations.
