The surface of concrete structures is subject to abrasion when they are constructed in sea water where ice movement is active. Abrasion occurs due to the friction force between ice sheets and the structure caused by the ice force working on the structure.
Over the past ten years we have been conducting experiments with many types of concrete and their possible coating materials to find their characteristics of abrasion due to movements of ice sheets. In this experiment we calculated the abrasion rates (average amount of abrasion per 1km movement of ice sheets) of various kinds of stone needed to estimate the abrasion amount due to movements of ice sheets which contain sand particles or not, and we also clarified the mechanism of abrasion.
