The relationship between the prism and cube compressive strengths of recycled aggregate concrete is significantly different from that of normal aggregate concrete. However， the prediction accuracy of existing models is relatively low and the discrepancy between predicted results of these models is relatively high. 139 groups of test data in literatures were collected and analyzed， and the significant influences of the replacement ratio， water absorption ratio and the compounding effect between these two parameters were disclosed. A model for the relationship between the prism and cube compressive strengths of recycled aggregate concrete was proposed， with the coefficient of variation being only 5.4%. For the convenience of usage， a simplified calculation model based on the recycled aggregate classification was also proposed. The results of the model analysis show that the model uncertainty follows a normal distribution and is independent of the key parameters. It is suggested that the correlation between the model uncertainty and the key parameters can be ignored when the model is used for reliability analysis.
