文摘

•: Identification of cement paste and aggregates in concrete by ultrasound.
•: Frequency bands selection was based on frequency domain analysis of ultrasound signals.
•: The method assumes two distinct behaviors of aggregates and cement paste during hydration.
•: Transversal and longitudinal wave transducers ranging from 50 to 500 kHz were used.
