Abstract:Abrasion resulting from the movement of sea ice and fresh water ice must be considered during the design of concrete marine structures and concrete bridge piers for regions where the sea freezes in winter. Such areas include the Arctic Ocean, the Sea of Okhotsk, the Gulf of Bohai, the Beaufort Sea, the Bering Sea, the Gulf of Bothnia, and places where rivers freeze in winter. Movement of the ice sheet is both horizontal, caused by the tidal currents and wind, and vertical, due to tidal ebb and flow. Therefore, it is very important in the design of concrete structures in very cold regions to clarify the amount of abrasion due to ice-concrete motion. Through a systematic series of experiments, the authors have obtained the following information: 1) a relationship between sliding distance and amount of abrasion for various concretes and coatings; 2) a relationship between ice pressure on a concrete specimen (contact pressure) and amount of abrasion at the concrete surface; 3) the relationship between ice strength and abrasion rate; 4) the relationship between abrasion rate for various concretes and ice with fine entrained sand; 5) the degree of contamination by sand in actual river and lake ice in Hokkaido, Japan; and 6) a method for estimating the abrasion of concrete structures due to a movement of an ice sheet.
