Influence of raw meal composition on clinker reactivity and …
The raw materials are proportioned in front of the raw mill according to the targeted raw mix design. The raw mix design takes into account the desired clinker composition. As presented in table 3, the chemical compositions of clinker samples were conducted by XRF.

In practice, however, clinker composition is largely determined by the compositions of the locally-available raw materials which make up the bulk of the raw meal. Supplementary materials are used to adjust the composition of the raw meal but cost and availability are likely to determine the extent to which they are used.

In our understanding, the main challenge in using HI-IOT as a raw material is to keep clinker reactiveness, adopting an LSF equal to or higher than 0.96 (recommended for clinker Portland) [22] for the "raw meal" as adopted in this manuscript. The HI-IOT use may guarantee a proper formation of liquid phases during the clinker formation.
