Hydration 8: Aluminates

Description

This lecture covers the hydration of aluminates in cement chemistry, focusing on the reactions involving C3A and sulfate ions. Topics include the formation of ettringite, monosulfo aluminate, and AFm phases, as well as the effects of limestone addition. The instructor discusses the impact of gypsum on aluminate reactions, the heat flow during hydration, and the multiple aluminate peaks observed. The lecture emphasizes the importance of sulfate in modifying aluminate reactions and the sequential nature of reactions involving silicate and aluminate phases.
