Alkali-aggregate Reactions. Some aggregates containing reactive silica will react with the alkalies in cement-sodium and potassium oxides-to form an alkali-silica gel which takes up water and swells. This causes abnormal expansion and map-cracking of the concrete.ome aggregates containing reactive silica will react with the alkalies in cement-sodium and potassium oxides-to form an alkali-silica gel which takes up water and swells.
