Homework Answers
Solution A is correct
the C3A is linked to sulphate attack resistance when the sulphate is coming from the environment. Briefly, the hydration of C3A, together with added gypsum to cement, provide ettringite formation, which later becomes a monosulfate. The monosulfate, when in contact with the sulfate that came from the external environment became unstable and reacts back to ettringite in a strongly expansive reaction. This, occurring in the hardened concrete, produce intense material degradation. Thus, it is important to limit the C3A content of cements for the production of concrete that will be applied in environments rich in sulfate.
