Equation for the Degradation of Uniaxial Compression Stress of Concrete due to Freeze-Thaw Damage

Table 2

Quasi-static compression test results of concrete after different numbers of freezing-thaw cycles.

Number of freeze-thaw cycles	fcm (MPa)	εcm (10^−6)	εcm (10^−6) (model code 2010)
0	44.93	2150.3	2400
25	40.10	2482.0	—
50	31.57	3095.0	—
75	19.67	4696.7	—

Note. f_cm is the peak stress and ε_cm is the strain at peak stress.
