Biogenic Sulfuric Acid Attack and Case Studies

In describing BSA, De Belie8 and others1 state that sulfuric acid reacts first with calcium hydroxide in concrete to form gypsum. The gypsum then reacts with monosulfate to form ettringite, resulting in a large volume expansion that causes internal pressure and deterioration of the concrete matrix.1,8 Formation of ettringite through the reaction between gypsum and calcium aluminate hydrate (monosulfate) is also a major reaction of “conventional” or “classical” sulfate attack.3,9,10 However, ettringite or thaumasite, observed in other forms of sulfate
