Cement-Admixture Incompatibility

The hydration product that we would normally like to see form in this initial phase is a mineral called ettringite. But if a sufficient amount of the inter-ground gypsum used to control flash set is not present when the cement …

Ettringite

Ettringite is a primary constituent of hydration of Portland cement concrete. Its formation plays an important role in the control of setting. Minor amounts of secondary ettringite are often encountered in air voids of hardened concretes, regardless of the type of cement used. This secondary ettringite, evidently developed in the walls of the ...
