egregation is the unintentional separation of the fresh components of concrete or mortar, which can be caused by bad
proportioning, insufficient mixing, or excessive vibration. Segregation can have negative impacts on the mechanical,
transport, and durability properties of the cured product. While there are several tests that can measure concrete at the beginning
of hardening or in its fully hardened state, these are generally based on the percentage of the coarse aggregates between the top
and the bottom of the samples. Consequently, the results do not provide a full description of the state of the material or a basis for
its long-term performance. To begin to address this deficit, this paper investigates the potential of using ultrasonic pulse velocity
(UPV) as a means to identify and characterize segregation in traditional and self-compacting concrete (SCC), which is known to
be particularly prone to segregation, because of its high fluidity level.
