Concrete-ice abrasion laboratory experiments

Concrete-ice abrasion is a concrete surface degradation mechanism due to ice-structure interaction. The topic is especially relevant for concrete gravity-based structures in the Arctic offshore. Experiments have become the main evaluation method for concrete durability under ice abrasion. The paper presents concrete-ice abrasion experiment between sawn concrete surface (cubic compressive strength is 90 MPa) and unidirectional fresh water ice. The experiment included two experimental conditions, with varied temperature of the concrete surface. Results demonstrate the load cells response, coefficient of friction and abrasion depth. Based on our results and observations we identified wet and dry abrasion types. The first type caused most damage, whereas second one caused minor damage.
