Abstract
Medium-scale tests were conducted to measure and observe the strength and failure behavior of freshwater ice rubble. A custom box measuring 3.05â¯mâ¯Ãâ¯0.94â¯m à 0.94â¯m, with Plexiglas walls was built so that failure mechanisms could be observed. Ice rubble beams of nominal thickness 50â¯cm were produced by placing randomly sized ice pieces into the box filled with water at its freezing temperature. After the specified consolidation time, ranging between 0.2 and 70.5â¯h, the ice rubble beam was deformed by pushing a platen vertically downwards though the center of the beam until failure. For consolidation times less than 4â¯h, the ice beam failed progressively and tended to fail by shearing on macroscopic scale. At times greater than 4â¯h the beam failed by bending. The change in failure behaviour has been attributed to the degree of bonding between ice blocks.
