ice wedging
Frost action is a type of mechanical weathering. It occurs when water seeps into cracks in rocks, freezes, expands, and causes the rock to break apart.

which concrete resist frost action
Frost action is a type of physical weathering caused by the expansion of water when it freezes and contracts when it thaws. This repeated freeze-thaw cycle weakens rocks and can lead to the breakdown of rock surfaces.

Physical weathering
Some types are thermal stress, frost wedging, abrasion, pressure fractures (pressure release), hydraulic action, and salt crystal expansion.
The particular frost action that is an example of mechanical weathering is called frost wedging. This occurs when water seeps into cracks in rocks, freezes, expands, and ultimately causes the rock to break apart.
