| Résumé | Maintenance and repair of ice-worn concrete structures in marine environments are ongoing challenges. Practical solutions for reducing ice-wear for large-scale applications have had marginal success rates to date. We still do not really know the relative degrees of abrasion caused by mechanical wear, freeze-thaw cycling, pore water pressure, or seawater chemical effects. What is happening at the interface between ice and concrete and is there a link between wear and adhesion processes? Many studies have examined ice and concrete adhesion: twist, push and pull tests on concrete piles frozen into ice; direct shear tests of ice on concrete; and investigations into the frictional wear of concrete by ice. How do contact mechanics influence the shear and tensile adhesion bonds between these two substances? This paper outlines a programme that seeks to inform not only our knowledge of adhesion loading, but also how adhesion may influence the initial high rate of wear that is common to ice abrasion of concrete. The presented test programme is using a suite of methodologies to examine ice-concrete adhesion. Three approaches are outlined, with an eye towards answering the questions above, for a comprehensive evaluation of ice-concrete adhesion bonding. |
