Experimental investigation of soil volume changes during freezing and thawing
… causes water in the soil pores to turn into ice, which expands, leading to ice lens formation and frost heave. Thawing causes the ground to settle, potentially damaging infrastructure. To investigate these challenges, this study employs a new Frost Heave Apparatus (FHA) capable of performing …

Internal frost damage in concrete - experimental studies of destruction mechanisms
… The effect of these parameters on formation of ice, and on the behaviour of the concrete during freeze-thaw should be monitored. In this way it was imagined that the individual effect of each fundamental parameter could be identified. The aim was to use the experimental results to test different …

Investigated physical/strength properties and elastic constants of fimbul granular ice applied to ice cliff stability analysis
… Radar (GPR) survey was conducted on the Fimbul ice shelf edge to determine a safe cargo offloading zone from the SA Agulhas II ship. The survey showed subsurface cracks which created concerns of shelf failure, risking the lives of crew and the ship stationed at the bottom of the cliff. To assess …

Moisture Conditions and Frost Resistance of Concrete in Hydraulic Structures
… damaged by frost action and later removed due to ice abrasion. During the next snowmelt runoff period, the process starts all over again. Experimental results obtained in this work confirm this deterioration process. Spalling of concrete has been observed below the water level in water retaining …
