Abrasion of concrete by ice in arctic sea structures

Abstract

The concrete structure is subjected to a heavy mechanical load near the water level, due to the moving ice sheet as it breaks against the structure. Furthermore, recurrent freeze-thaw cycles deteriorate the concrete, if it has not been designed to resist recurrent freezing in marine conditions. The abrasion of concrete in arctic sea structures can be estimated by means of the laboratory abrasion test development in connection with the research and other laboratory tests
