Abstract

Vertical scanning interferometry and XPS show the reaction of CaCO₃ with the hydration retarder nitrilo-tris-(methylene)phosphonic acid follows a pathway of dissolution of the calcium followed by precipitation of a calcium phosphonate; subsequent surface reorganization/restructuring of the calcium phosphonate exposes the underlying CaCO₃ for further hydration.
