摘要：

Currently, the extension of life span of concrete structure is urgently needed. Therefore, it is important to predict the future deterioration of the concrete structure. The deterioration accompanied with alkali-silica reaction is one of the factors associated with durability. Generally, the aggregate expansion which is caused by the alkali-silica reaction brings about cracking, and the crack may decrease the durability with changing the mechanical properties of the concrete structure. Though there are a number of researches on alkali-silica reaction, the deterioration prediction under complex stress condition such as pre-stressed concrete is not well discussed. In this study, the degradation model for pre-stressed concrete structure is proposed and the validity of the model is ex¬amined through the comparison with exposure test of alkali-silica reaction using a pre-stressed concrete.
