Earlier in this forum free I posted an article " Features of Synthesis C3S in Highe Sulfur Clinker (Part 1). I have updated the article combining part 1 and part 2 calling it"Study of the reasons for blocking C3S formation in the presence of SO3 and finding ways to overcome blockages." Because the crooks want to get it published money, post articles in open access. Also give a link to my patent which describes the procedure. From this site you can download the patent in pdf format.
