Mechanical behavior and its modeling of ASR deteriorated concrete in the case of severely damaged such as fracture of steel in the concrete

对因膨胀过度而劣化的ASR混凝土，需要制定相应的养护方法。本研究之主要目的为探讨不同骨料配制之ASR劣化混凝土之力学行为。这些混凝土的膨胀率均在0.8%以上。试验结果表明，活性骨料的种类对混凝土的力学性能影响不大。此外，建议将所得的ASR劣化混凝土力学性能数据设计成最小值，用于评估ASR劣化混凝土构件的性能。

It is needed to be established the maintenance method for ASR deteriorated concrete due to an excessive expansion. Main purpose of this study is to be clarify the mechanical behavior of ASR deteriorated concrete that made with various aggregate. The expansion of those concrete were over 0.8%. As results, it is cleared that the effect of type of reactive aggregate on the mechanical property is not significant. Furthermore, it can be recommended that the minimum value was designed by using the these obtained mechanical data of ASR deteriorated concrete in order to use for the evaluation the performance of ASR deteriorated concrete member.
