Etude expérimentale du frottement glace-béton
To understand the role of the contact conditions in the friction of ice on structure, we have performed cyclic friction tests at—10° C between laboratory grown columnar ice and a micro-concrete. This paper defines the performed tests. The obtained results allow the study of the mechanical behaviour of the interface and of the wear of concrete. Effects of time and contact conditions on friction are analysed, which leads to the formulation of empirical friction laws and to the definition of the physical mechanisms involved at the interface. The role of these mechanisms is tested in a simple model of the ice-concrete contact.
