the early age strength and hardening of concrete plays a crucial role in
ensuring the structural integrity and durability of concrete structures.
Ultrasonic guided waves have emerged as a promising non-destructive testing
technique for assessing concrete properties. This review paper aims to provide
an overview of the utilization of ultrasonic guided waves for the early age
assessment of concrete strength and hardening. The paper begins by discussing
the fundamental principles of ultrasonic guided waves and their interaction
with concrete materials. It highlights the advantages of using guided waves,
such as their ability to propagate over long distances and penetrate through
concrete structures. The review then explores various techniques employed for
generating and detecting guided waves, including piezoelectric transducers,
air-coupled transducers, and laser-ultrasonics. Furthermore, the paper presents
a comprehensive analysis of the different parameters that can be extracted from
ultrasonic signals to assess the early age strength and hardening of concrete.
These parameters include wave velocity, attenuation, reflection, and scattering
characteristics. The influence of various factors, such as moisture content,
temperature, and mixture proportions, on the ultrasonic response of concrete is
also discussed. Moreover, the review discusses the challenges and limitations
associated with the application of ultrasonic guided waves in early age
concrete assessment. It addresses issues such as signal interpretation, wave
dispersion, and the presence of air voids. Additionally, recent advancements in
signal processing techniques and data interpretation methods are highlighted.
In conclusion, the utilization of ultrasonic guided waves for the early age assessment
of concrete strength and hardening shows great promise. This review paper
provides valuable insights into the current state-of-the-art in this field and
offers recommendations for future research directions.
