    Sulfate attack on concrete is a key durability problem. Internal sulfate attack (ISA) on concrete is a reaction between sulfates present in the original mix of concrete and the calcium aluminate in cement and water, which can show signs of deterioration [].In the early stage of hydration, the gypsum reacts with tricalcium aluminate to form ettringite (AFt), which does not damage concrete.
