| Abstract: | Based on the fracture mechanics theory, combined with thermodynamics principle, the principle of freeze-thaw damage to concrete is analyzed; on account of Paris formula, the residual life prediction formula after the freeze-thaw cycle is derived on the basis of equivalent to the freeze-thaw damage concrete, in order to provide a reference for the researchers. |
| Keywords: | fracture mechanics thermodynamics freeze-thaw damage residual life |
