Effect of Sulphate Attack on Self compacting Concrete

The result of the study indicated that the replacement of cement with 10% lime improved the durability of Self–compacting concrete. The loss in mass, compressive strength and sorptivity of cubes were found to be negligible under Sulphate attack. It was observed that limestone and quarry dust powder resists Sulphate attack within tolerable limits.

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
