“…We interpreted the higher rate from 0 to 1 km as early-stage wear, where severe initial contact took place [21], and the lower rate of the further abrasion from 1 to 3 km as a less severe wear mode [21]. The current results are remarkably different from those from early studies of concrete-ice abrasion [22]. At that time, the results showed three stages of concrete abrasion by ice on a mould concrete surface.…”

Concrete structures in the Arctic offshore are often exposed to drifting ice causing abrasion of concrete surfaces. This paper presents the results of a laboratory study of concrete-ice abrasion. The sawn concrete surfaces (two high-performance concrete mixes and one light weight mix of concrete) were exposed to sliding freshwater ice under 1 MPa pressure for 3 km of sliding distance. The effect of concrete compressive strength, ice consumption, and the coefficient of friction on abrasion was studied simultaneously. The results show a low abrasion of concrete, the maximum abrasion depth (0.35 mm) after 3 km of sliding test was found for the concrete samples with the lowest compressive strength. All tests showed a severeto-mild wear transition, with the maximum wear rate in the first sliding kilometre. The coefficient of friction was high when ice consumption was high due to ice spallation and pulverization, whereas the coefficient of friction was not directly correlated to the wear. The wear or consumption of the ice (abrasive) was in the order of 30000-100000 times that of concrete despite of its strength and stiffness 1-10 times lower than that of concrete.

“…This numerical study is related to laboratory experiments performed with the equipment available at NTNU, Department of structural engineering [5]. At the NTNU lab concrete samples for laboratory experiments are rectangular in shape, 100 by 300 mm 2 , with height 50 mm. A cylindrical sample of ice with diameter 73.4 mm slides along the upper horizontal concrete surface with a typical average pressure of 1 MPa (Fig.…”

“…So far, the assessment of concrete ice abrasion durability has mainly been evaluated experimentally, whereas less work has been done to model the actual degradation process. Laboratory measurements of concrete-ice abrasion are usually performed by concrete sliding on ice, see for example [2,3] or by ice sliding on concrete, see for example [4,5]. In this paper we present a study on the ongoing development of a FEA-model to understand the effect of variations in material-, surface-and load parameters of concrete and ice on resulting concrete ice abrasion.…”

Abstract. The last decades the concrete-ice abrasion process has been well known as a concrete surface degradation mechanism due to ice sliding. The topic is especially relevant for concrete gravity based structures in the Arctic offshore. The article presents a numerical model in which the onset of wear in the concrete-ice abrasion process is simulated. The simulations are performed on meso-scale, which means that concrete is modelled as a three-phase material in which paste, aggregates and the interface transition zone are distinguished. Lattice modelling is adopted for the numerical modeling. Hertzian contact theory which predicts excessive tensile stresses on the concrete surface due to sliding of ice asperities is used as an analytical basis for the numerical model. It was concluded that such model is able to capture both surface and subsurface cracking in the concrete.

This research is devoted to the decision of a problem of modeling the wear process of concrete. In paper presents a wear model of concrete as heterogeneous material on the basis of the theoretical and experimental contact mechanics methods approach. The model predicts that its abrasion strength depend on physical and geometrical characteristics of cement matrix and aggregate. The theoretical modeling of a surface with the strengthened ore softening areas is applied to optimization of concrete structures. The experimental results support these theoretical predictions.
