The carbonation process of concrete cover is one of the most common reasons for limiting the durability of reinforced concrete structures. At the same time, the positive role of concrete carbonation is becoming increasingly important, as it can reduce the carbon dioxide content in the air as a result of sequestration and chemical binding in concrete in the permanent form of calcium carbonate. This issue is important in the implementation of the sustainable development strategy for the construction industry, as part of the carbon balance of the cement and concrete cycle and the analysis of their carbon footprint. The aim was to evaluate the concrete carbonation course, which was produced with the participation of fly ash from the combustion of sewage orchards over time and to describe this phenomenon in mathematical form.

摘要

The carbonation process of concrete cover is one of the most common reasons for limiting the durability of reinforced concrete structures. At the same time, the positive role of concrete carbonation is becoming increasingly important, as it can reduce the carbon dioxide content in the air as a result of sequestration and chemical binding in concrete in the permanent form of calcium carbonate. This issue is important in the implementation of the sustainable development strategy for the construction industry, as part of the carbon balance of the cement and concrete cycle and the analysis of their carbon footprint. The aim was to evaluate the concrete carbonation course, which was produced with the participation of fly ash from the combustion of sewage orchards over time and to describe this phenomenon in mathematical form.
