Significance of Delayed Ettringite Formation and Damage Mechanisms

Cracks due to delayed ettringite formation

Significance of Delayed Ettringite Formation and Damage Mechanisms Ettringite is formed in hydrated Portland cement system as a result of the reaction of calcium aluminate with calcium sulfate, both present in Portland cement. In the cement system, the presence of ettringite depends on the ratio of calcium sulfate to tri-calcium aluminate (C3A); when this ratio … Read more
