Abstract: This study comprises an approach of ultrasonic testing application to understand the influence
of microstructural and constitutive components of Cement Based Materials (CBM) to the
ultrasonic wave propagation. Nondestructive testing (NDT) represents a significant advance
in a quality control of CBM and the concrete structures field. From NDT methodologies, the
ultrasonic testing represents an important family. It is well-known the widespread application
of the Son-Reb methodology to determine the level of integrity and bearing capacity of the
structures. The ultrasonic monitoring allows determining the strength activity during the
setting and hardening processes meanwhile the Carino’s maturity method predicts the
compressive strength in concrete mixed and it is used on construction sites. The combination
of procedures seems to be affordable and it will contribute definitely to the universality of a
unique method. With this research work, it is shown an experimental set-up based on cement
pastes and mortars varying w/c ratio and aggregate proportion to obtain a discrete uniform
variation of microstructures. The object is to analyse the ultrasonic parameters (velocity, wave
reflection factor and centroid frequency) during the curing process and to assess them with
microstructure and ultrasonic modelling (Hymostruct Lite and Wave2000 software©) and with
experimental tests (nanoidentation, porosity and strength tests).
