Revealed the strength variation of concrete C30 and C50 after the cold in the initial .Using the gray prediction theory which from the cybernetics to analyze the test results after the initial cold.The results show that the results obtained by the formula is consistent with the experimental results, the residuals are within the control range. The experimental in cold for 120 days is much closer than theoretical values when compared with the residual for 90 days.Research shows that with the increase of initial freezing time, the loss rate of concrete strengthincreased.And the residuals showed a significant increasing trend when the number of freeze-thaw cycles increased.
