Wideband Microwave Characterization of Alkali-Silica Reaction (ASR) Gel in Cement-Based Materials

Abstract

Alkali-silica reaction (ASR) and its effect on cement-based infrastructure is an ongoing concern for ensuring long-term performance. However, it remains challenging to identify ASR damage in concrete before damage progresses and ASR gel staining, expansion and cracking compromise serviceability. This research demonstrates that microwave materials characterization is an effective method by which ASR gel in cement-based materials can be detected and that materials containing ASR gel can be distinguished from those without. Further, this work provides a basis for the development of field evaluation techniques and lab-based investigations to better understand the relationships between concrete composition and ASR damage propagation.
