Experimental study of the friction of ice over concrete under simplified icestructure interaction conditions

Abstract

Cyclic friction tests between laboratory grown columnar ice and micro-concrete plates were performed at –10°C to study ice–concrete friction under conditions similar to those observed in ice–structure interactions. This paper presents the results obtained in terms of friction coefficients. Effects of time and contact conditions are analysed, and conclusions about the effective physical mechanisms of friction are drawn. These conclusions are validated by a simple model of the ice–concrete contact.Key words: ice, structure, concrete, contact, interaction, friction, law, model, viscoplasticity, roughness.
