Description
Summary:The characterization of a cement mortar by resonance of ultrasonic waves makes it possible to follow the evolution of its parameters in real time. We propose an experimental and then theoretical determination of the resonance characteristics. From the representation of the reflection coefficient in the complex plane, we find the resonance frequencies, but a new element, the resonance widths can be obtained by a complementary theoretical approach. The used approximations lead to an expression of the resonance width, a function of the parameters of the mortar. Experimental measurements show that it makes it possible to detect any modifications to the microstructure of the mortar during its hydration. The measurement of the resonance width can therefore be used as an effective means of monitoring and non-destructive testing.
