Abstract: The effect of C3A polymorphism, the calcium sulfate source, and the addition of limestone on the hydration kinetics and rheology of cement pastes and their interaction with a lignosulfonate-based admixture were analyzed. ...

Abstract: Tricalcium aluminate (C3A) is the most reactive phase in portland cement clinker. In the study of the C3A hydration process, the use of synthetic samples is often preferred over clinker-sourced samples due to the absence ...
