Freezingthawing durability of concretes subjected to single damage factor (SDF), double damage factors (DDF) or multiple damage factors (MDF) was studied by accelerated freezingthawing test. Dependence of multiple-factor service life (MFSL) and double-factor service life (DFSL) on single-factor service life (SFSL) was investigated. Results show a linear relationship between the DFSL, under combined action of deicing salt and freezingthawing cycles, and SFSL under freezingthawing cycles. The DFSL under combined action of sulfate attack and freezingthawing cycles, the DFSL under combined action of salt lake bittern attack and freezingthawing cycles and the MFSL under the combined action of carbonization, salt lake bittern attack and freezingthawing cycles are all power functions of the SFSL under freezingthawing cycles. While in presentation of bending, both DFSL under flexural load and freezingthawing cycles, and MFSL under flexural load, deicing salt and freezingthawing cycles are decaying exponential functions of load.
