Abstract In order to study the coupling action of freeze-thaw and sulfate corrosion on the mechanical properties of early-age concrete, in this study, three early-age concrete tests with water-binder ratios based on the actual environmental conditions in Ruoqiang area of Xinjiang Province were carried out, namely, freeze-thaw cycle, sulfate corrosion and freeze-thawing sulfate corrosion coupling test, therefore the time evolution law and action mechanism of early-age concrete strength under different environmental action conditions and water-binder ratio interaction were analyzed. Meanwhile, this study based on grey system theory and genetic algorithm, the variable weight buffer GM (1, 1) model of early-age concrete strength was established. The results show that the corrosion resistance coefficient of early-aged concrete increases first and then decreases with the increase of the number of freeze-thaw cycles under the same environmental working conditions, and the water-binder ratio is negatively correlated with the corrosion resistance coefficient of early-aged concrete in the final corrosion period. Under the condition of the same water-binder ratio, compared with the single freeze-thaw cycle condition, the freeze-thaw-sulfate corrosion coupling condition has a higher impact on the final value of corrosion resistance coefficient of early-age concrete. The maximum average prediction error of the early-age concrete strength prediction model is only 1.893%, which has a good prediction accuracy, and would provide a reference for the evaluation of the service state of concrete structures in cold and saline soil areas. By evaluating the durability of early-age concrete under different environmental working conditions with the prediction model, the study concluded that: the predicted service life of early-age concrete with water-binder ratio of 0.26, 0.32 and 0.38 is respectively 75.3 a, 24.6 a and 15.3 a under the freeze-thaw cycle, while the predicted service life of early-age concrete with water-bin-der ratio is reduced to 30.7 a, 22 a and 12.7 a under the coupled freeze-thaw and sulfate corrosion condition.

Key words： coupling action of freeze-thaw and sulfate corrosion early-age concrete strength evolution law genetic algorithm variable weight buffer operator GM (1,1)
