Abstract

This project proposed an integrated approach for the non-destructive evaluation of the health status – represented by compressive strength – of any concrete, including well-cured (or intact) and degraded (or partially damaged) due to freeze-thaw cycling. To use this approach, no pre-recorded information (e.g., mixture proportions of concrete, curing and maintenance history, and service history) is needed. Instead, several conventional non-destructive testing methods (NDTs), assisted by hyperspectral camera, can be employed to generate a dataset that informs a pre-trained artificial intelligence (AI) to predict strength. As the core of this approach, the dedicated AI was trained through this project. To this end, hundreds of concrete specimens of 17 distinct mixture proportions were prepared and cured to an age of 56 days. They were then subjected to freeze-thaw cycles. The NDTs were used to trace the development of various physicochemical features of the concrete mixtures and compressive strength was tested following the curing and degradation processes to curate a first-of-its-kind database, and the AI was trained and validated using this database.
