本文的主旨是表明，需要采用一个综合的材料和结构设计策略，开发技术，是有意义的和有效的识别，评估和修复的混凝土元件和混凝土结构的影响和损坏的AAR。结果表明，在真实的结构中，暴露于环境和气候变化是影响混凝土膨胀率和总膨胀的主要因素。AAR还与测试和测试方法密切相关，因此材料和结构矫正需要一种全球性的方法，包括诊断方法，确定未来扩展潜力的测试，选择性密封裂缝和保护免受环境攻击，使用非破坏性测试技术进行结构评估和结构加固。
The overall thrust of this paper is to show that an integrated material and structural design strategy needs to be adopted to develop techniques that are meaningful and effective for the identification, evaluation and rehabilitation of concrete elements and concrete structures affected and damaged by AAR. It is shown that exposure to environmental and climatic changes is the major factor influencing the rate of expansion and total expansion of concrete in real structures. AAR is also closely and intimately involved with testing and test methodologies so that material and structural rectification requires a global approach involving diagnostic methods, tests to establish the potential of future expansion, selective sealing of cracks and protection from environmental attack, structural evaluation using non-destructive test techniques and structural strengthening.
