Sulfate Attack an overview | ScienceDirect Topics

Sulfate attack is another possible deterioration mechanism of concrete. It can have endogenous origin (developing without any contribution from the environment) or exogenous origins (such as sulfates contained in the soils or in liquids) (Germain, 2008; Neville, 2004).In both cases, the consequence is some volume expansion owing to the delayed formation of ettringite, which is an expansive ...
