Certain frost-susceptible soils expand or heave upon freezing as a result of water migrating via capillary action to grow ice lenses near the freezing front. This same phenomenon occurs within pore spaces of rocks. The ice accumulations grow larger as they attract liquid water from the surrounding pores. The ice crystal growth weakens the rocks which, in time, break up. It is caused by the expansion of ice when water freezes, putting considerable stress on the walls of contain… WebSep 25, 2024 · Frost action is caused by repeated actions of freezing an thawing, when a rock is continuously frozen the cracks in the rock increase or become bigger and bigger …
WebFrost action is the repeated cycle of ice formation and ice melt in the pore spaces and fractures of rocks causing disintegration of the rock. When water in rock pores freezes, its volume increases by about 10%. This can create a significant amount of pressure on rocks.
