ResumoAbstract Portland cements containing tartaro- and titanogypsum were respectively hydrated for up to two hours at a water: cement ratio of 0.5. They were compared with a Portland cement containing high grade natural gypsum hydrated similarly. The cement containing tartarogypsum produced much more ettringite than those with titanogypsum and natural gypsum. Comparisons were made with previous examinations of the hydration of Portland cements containing other by-product gypsums. Reasons for the observed hydration behaviour of the Portland cements with tartaro- and titanogypsum are discussed.
