Monitoring of self-healing cementitious materials through contactless ultrasound [PDF]

MATEC Web of Conferences, 2023
Self-healing cementitious composites provide an alternative to labour-intensive and costly manual repairs. While a cementitious blend possesses an inherent ability to repair its own damage through autogenous healing, an enhancement of the self-healing ...
