ABSTRACT
Internal swelling reactions (ISR) are amongst the most harmful deterioration mechanisms affecting the durability, serviceability, and overall performance of critical concrete infrastructure around the globe. Over the years, several approaches have been developed worldwide to assess the condition and manage ISR-affected structures. However, several challenges have still been faced in the proper selection and efficiency of laboratory and field tools to assess the condition, along with rehabilitation strategies and management protocols to mitigate effects and extend the service life of affected infrastructure assets. This paper aims to conduct a thorough literature review on the topic, showing the recent developments and current challenges faced by engineers, infrastructure owners and researchers dealing with ISR-affected structures. In addition, it will highlight current research needs and future opportunities.
