Hydration Mechanisms of Portland Cement: Topochemical or Through-Solution Reaction?

When we simulate the hydration process of Portland cement, it is of significant importance to know the hydration mechanisms. Basically, there are two mechanisms for the hydration of Portland cement, viz. Topochemical and Through-Solution Reaction. 1 Topochemical Reaction Concept Immediately after the first contact of the cement with water a calcium-rich silicious clinker would liberate […]
