Liquid-Like Water in Frozen Porous Media and Surface Melting of Ice

该奖项旨在支持一个为期3年的跨学科项目，研究多孔介质和冰蒸气表面的冰水平衡和输送现象。实验将根据最近在表面融化的基本物理方面的进展和多孔土壤和岩石中未冻水的大量文献来设计。理论研究和实验室测量将结合起来，以了解影响冰和各种矿物表面之间不冻水膜形成的因素。这项研究具有广泛的实际应用，包括更好地理解由于霜胀引起的人造结构的破坏，对混凝土和其他多孔材料的霜冻损伤，以及冰与道路和其他表面的结合。

This award is for support of a 3 year interdisciplinary project to study ice-water equilibrium and transport phenomena in porous media and at ice-vapor surfaces. The experiments will be designed in the light of recent advances in the basic physics of surface melting and the extensive literature on unfrozen water in porous soils and rocks. Theoretical studies and laboratory measurements will be intergrated to achieve an understanding of the factors which influence the formation of unfrozen water films between ice and various mineral surfaces. This research has widespread practical applications including better understanding of the disruption of man-made structures due to frost heaving, frost-induced damage to concrete and other porous materials, and ice bonding to roads and other surfaces.
