AN EXPERIMENTAL STUDY ON ABRASION OF CONCRETE DUE TO SEA ICE

Laboratory tests were performed to investigate how sea ice abrades concrete and to clarify what the major factors are in estimating wear depth of concrete due to sea ice. This paper outlines a new apparatus developed by the authors for ice abrasion testing and the significant results obtained by using the apparatus. The tests were carried out by changing various parameters which influence the wear rate of normal weight and lightweight concrete. They included type of aggregate, concrete strength, ice temperature, contact pressure, and relative velocity between ice and concrete. Among these, the ice temperature and contact pressure were found to be the most significant parameters. The results were summarised in chart form, as the first step toward realising accurate estimation of wear rate. The effect of surface treatment including polyurethane resin lining, resin mortar lining and polymer impregnation was also examined.
