The burning of fuel oil with high sulfur content in diverse industrial segments results in the generation\nof oxidized sulfur compounds (SOx). These emissions, directly or indirectly, lead to the deterioration\nof air quality with consequences including the development of lung diseases in the\nsurrounding population, the generation of acid rain and damage to civil constructions, such as\npublic buildings, public squares, historic monuments, bridges, etc. This article describes the mechanisms\nof corrosion that occur in reinforced concrete deterioration observed in an industrial\nplant by the action of direct emissions of sulfur dioxide. SO2 in this case study is from the burning\nof fuel oil high sulfur content from chimney of an industrial boiler. The deterioration of concrete\nwas evaluated in the laboratory showing the formation of calcium sulfate and calcium sulfate hydrate\nassociated with aluminum oxide (Al2O3) and calcium oxide (CaO).
