The paper is a review of a 25 years long record with analyses of thin sections and fluorescein impregnated sections (slabs) as tools to characterize initial concrete quality and causes of deterioration of concrete of various qualities and suffering from various deleterious actions – primarily in Denmark. The paper demonstrates the world of opportunities and the advantages of the applied techniques by various examples from practice, covering early frost action, freeze–thaw attack, alkali‐silica reactions, acidic attack, exposure to fire, quality control of repairs, and defects in the construction phase, etc. Also the limitations of the methods are discussed.
