TLDR
In this paper, different types of chemical by-product gypsum are described and their influence upon the early hydration behavior of portland cement is discussed. But no correlation was found between ettringite and setting behaviour.Abstract:
Different types of chemical by-product gypsum are described and their influence upon the early hydration behaviour of portland cement is discussed. When the portland cement contained by-product gypsum, more ettringite was formed than when natural gypsum was present. No correlation was found between ettringite and setting behaviour. Compressivestrength development was not adversely affected by the presence in portland cement of any of the by-product gypsumsexamined here. (Author/TRRL)read more

Effects of the clinker - gypsum grinding temperature upon early hydration of Portland cement
TL;DR: In this article, the temperature at which Portland clinker and gypsum are ground together to produce Portland cement is shown to influence the subsequent early hydration behaviour, and the results have been interpreted on the basis of a through solution mechanism involving primarily the reaction of tricalcium aluminate from the cement clinker component with available soluble Ca2+ and SO42− ions in the aqueous medium.

Early hydration behaviour of portland cement containing boro-, citro- and desulphogypsum
TL;DR: In this paper, it was found that Portland cements containing boro- and citro-gypsum produced considerably more ettringite than those with desulpho-and natural gypsum.

Microstructural and phase characteristics of phosphogypsum-cement mixtures
TL;DR: In this article, the effects of the tricalcium aluminate (C 3 A) content of stabilizing cement [Type II (1.3% C 3 A), and Type III cement (9.3%) on the microstructural and phase properties of gypsum/PG and cement mixtures, a potential road-base material, were studied.
