Semi-continuous ultrasonic sounding and changes of ultrasonic signal characteristics as a sensitive tool for the evaluation of ongoing microstructural changes of experimental mortar bars tested for their ASR potential

•Ultrasonic testing was used to study ASR of mortar bars.•Semi-continues ultrasonic testing of mortar bars was made.•Ultrasonic results showed good correlation with standard expansion tests.•Ultrasonic testing is more sensitive to concrete deterioration. Semi-continuous ultrasonic sounding of experi...
