The Crystallization Pressure of Ice—A Simple Experiment

Abstract Polycrystalline ice, growing from the melt, can exert a pressure against an extended obstacle, even though it is free to grow in other directions. Pressures of over 0.2 bar (20kN m -2 ) have been measured with simple apparatus. This phenomenon may be important in explaining the frost-shatte...

Description
Summary:Abstract Polycrystalline ice, growing from the melt, can exert a pressure against an extended obstacle, even though it is free to grow in other directions. Pressures of over 0.2 bar (20kN m -2 ) have been measured with simple apparatus. This phenomenon may be important in explaining the frost-shattering of rocks.
