Witryna18 wrz 2024 · The cycle tears up material in colder climates as they fluctuate around the freezing point, at 32 degrees Fahrenheit or 0 degrees Celsius. Also known as freeze/thaw weathering, frost weathering, and frost shattering, this debilitating system can eventually break your buildings down. The traditional explanation for frost weathering was volumetric expansion of freezing water. When water freezes to ice, its volume increases by nine percent. Under specific circumstances, this expansion is able to displace or fracture rock. At a temperature of -22 °C, ice growth is known to be able to generate pressures of up to 207MPa, more than enough to fracture any rock.
