摘      要：This paper presents a comprehensive review of modeling of alkali-silica reaction(ASR)in *** modeling is essential for investigating the chemical expansion mechanism and the subsequent influence on the mechanical aspects of the *** concept of ASR and the mechanism of expansion are first outlined,and the stateof-the-art of modeling for ASR,the focus of the paper,is then presented in *** modeling includes theoretical approaches,meso-and macroscopic models for ASR *** theoretical approaches dealt with the chemical reaction mechanism and were used for predicting pessimum size of *** models have attempted to explain the mechanism of mechanical deterioration of ASR-affected concrete at material *** macroscopic models,chemomechanical coupling models,have been generally dcveloped by combining the chemical reaction kinetics with linear or nonlinear mechanical constitutive,and were applied to reproduce and predict the long-term behavior of struetures suffering from ***,a conclusion and discussion of the modcling are given.
