A Dynamical Simulation Model of a Cement Clinker …
Cement comprises ca. 90% clinker, with the remainder being gypsum and other mineral additions (e.g. limestone). The strength of cement depends on its composition, especially the amount of C 3 S, and thus depends on the composition of the clinker, the clinker quality, to provide enough strength. In addition, considerable uctuations in the ...

The cement plant of tomorrow
The question is: What will cement plants look like once net-zero CO 2 has been achieved? From today's perspective, none of the new binding materials which are being discussed today have the potential to replace cements based on Portland cement clinker on a larger scale [11]. New binding materials and systems will be further developed and will ...
