hardness of clinker due to usage of petcoke
Since C2S is the least brittle of the four major clinker minerals, an increase in C2S over C3S will make the clinker harder to grind. (b) If you have a raw mix that is high in alkalis which are not balanced with sulphur, under oxidising conditions the sulphur from the petcoke will combine with the alkalis and produce a lot of alkali sulphates.Web
