ICE ABRASION ON CONCRETE; DATA AND TESTING

Ice abrasion is a very severe deterioration mechanism on a concrete structure and there are indications that the rate of deterioration may progress very rapidly even on high performance concrete. Field data of depth of ice abrasion on well known concrete compositions exposed to well known ice abrasion load conditions are rare. We have reviewed earlier published field data from e.g. light houses and laboratory data showing that the rate of deterioration depends largely on concrete quality in general and on ice exposure conditions in particular. Therefore we discuss further research possibilities within modeling-, laboratory- and field studies in order to proceed in the development of competitive concrete structures for sub arctic and arctic conditions.
