Combination of Milimeter Wave Spectroscopy, Ultrasonic Testing Techniques to Monitor Curing Evolution of TRC Plates

Non-destructive testing (NDT) techniques are used to study the mechanical properties of the materials without destroying, nor compromising, such properties. This paper focuses on two types of NDT methods in order to follow the curing process of textile-reinforced cementitious (TRC) composites and their cementitious matrix for the first 24 h after hydration. Millimeter wave (MMW)
spectroscopy has shown sensitivity to the chemical reactions involving water, whereas ultrasonic testing (UT) following the longitudinal wave velocity, as documented in the literature, is able to follow the development of stiffness.
