freeze-thaw cycle (weathering, surface or structural changes, ... Processes and Techniques (hierarchy name)) |
|
Note: Deteriorative weathering mechanism caused by cycle of fluctuation in temperature below and above the freezing point of water. At temperatures above freezing, liquid water seeps into cracks, expanding within them in the form of ice as temperature falls below the freezing point. Repeated freeze-thaw cycles may lead to deterioration of stone and such effects as spalling in masonry, and potholes in roads.

Additional Notes: |
|
| Dutch ..... Verweringsmechanisme dat wordt veroorzaakt door temperatuurschommelingen boven en onder het vriespunt van water. Bij temperaturen boven het vriespunt sijpelt water in scheuren en wanneer het vriest, zet het uit in de vorm van ijs Wanneer deze cyclus zich herhaalt, kan de toestand van steen verslechteren en kunnen er effecten optreden zoals versplintering in metselwerk en kuilen in asfaltwegen. |
