The main phases of Portland cement are calcium trisilicate (C3S) responsible for the initial strength at approximately 60% and calcium disilicate (C2S) the main phase at approx. 20%, responsible for the strength over time. CSA cement does not form any free lime like Portland cement, which results in a lower alkali content.

Sep 09, 2013 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.

Fineness of Cement Construction How

Apr 07, 2020 Fineness of Cement. One of the last steps in the manufacture of cement is the grinding of clinker mixed with gypsum. Because hydration starts at the surface of the cement particles, it is the total surface area of cement that represents the material available for hydration. Thus, the rate of hydration depends on the fineness of the.
