At pH <3 gypsum (C$ 2 H) is formed and remains stable. Gypsum can react with calcium aluminate hydrate and form ettringite. As a result, ettringite is pres-ent in the inner parts of concrete where pH remains higher (>4). With the continuing increasing sulfuric acid amount, pH values decrease also in the inner part of the concrete and transform
