Silastman,

I can't understand that.
Have you checked that the final state of the pressed raw mix is totally decarbonated?
What were the LOI of your samples in both experiments?
It might well be that the core of the pellets were not calcined, for example if the mechanical pressure blocks the decarbonation and would require higher temperatures than those you have tried.

I think you can't expect us to believe that without a very precise and detailled description of your experimental setup and your analysis.
Since this is well established fundamental physics, an explanation should also be provided, based on maisntream physics!

Ha-ha-ha dear lalbatros !

 You may be think -  these Russians so  stupid. If you are know the basics of thermal analysis, you should know that in thermal analysis simultaneously measure and record not only thermal effects, but also mass loss (LOI) and it’s was equal in the entire series of experiment. The results also do not contradict the fundamental basics of physics. Some theoretical aspects described me in this article.

Results for Portland cement is not yet publish.

Silastman,

Why don't you explain your point, instead of making wrong assumptions about my beliefs and about my knowledge?
My preferred readings in physics are the series written by Lev Davidovich Landau in collaboration with EM Lifshitz.

My point is that the enthalpy is a state function, and I assume you agree.
Therefore, the difference of enthalpy depends only on the initial and final state.
Do you imply that compressing the raw meal would change the initial state in a substantial way?
This is hard to believe.
If you had an explanation, I am sure you should be able to lay it down in only a few sentences.

Please, attach you paper to your post on this forum.
This is more convenient than these sharing sites.
It will remain definitively bundled with your post.

OK

I  attach paper. In short - compression increases the internal energy. Through the contribution of internal energy, the amount of heat energy, required for the reaction is reduce.
