Analysis of concrete damage by ettringite-thaumasite system formation

Gheorghe Croitoru

Rezumat/Abstract. The article investigates the peculiarities of concrete corrosion deterioration with ettringite and thaumasite crystallization in it. There have been defined the differences in the nature of concrete deterioration, in the early stages allowing to determine which components of the Ettringite-Thaumasite have dominant influence on the kinetics of destruction. The evaluation of the conditions that are most dangerous to the development of the processes of sulfate corrosion with Thaumasite has also been carried out.
