- •
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.
