Physical Causes <strong>of</strong> Concrete Deterioration<br />
3. Deterioration by Frost Action<br />
•When water freezes, there is an expansion <strong>of</strong> 9%.<br />
However, some <strong>of</strong> the water may migrate through<br />
the boundary, decreasing the hydraulic pressure.<br />
•Hydraulic pressure depends on:<br />
•Rate at which ice is formed.<br />
•Perme<strong>ability</strong> <strong>of</strong> the material.<br />
•Distance <strong>to</strong> an "escape boundary."<br />
