Ultrasonic Pulse Velocity for Real-Time Filament Quality Monitoring in 3D Concrete Printing Construction

open access: yesBuildings
Three-dimensional (3D) concrete printing (3DCP) has gained significant attention over the last decade due to its many claimed benefits. The absence of effective real-time quality control mechanisms, however, can lead to inconsistencies in extrusion ...

Perbedaan Hasil Uji Ultrasonic Pulse Velocity (UPV) Beton pada Mode Frekuensi Auto dan 50x

open access: yesIndonesian Journal of Laboratory
ABSTRACT.Ultrasonic Pulse Velocity (UPV) is a widely used non-destructive testing method for evaluating concrete, rock, and building structures by measuring the propagation velocity of longitudinal ultrasonic waves through concrete. UPV instruments are equipped with several operational parameters, including frequency, voltage, and signal transmission ...

Impact of Admixtures on Segregation in Self-compacting concrete: A Comparative Study Between Standardized and Ultrasonic Pulse Velocity (UPV) Methods

open access: yesThe Journal of Engineering and Exact Sciences
Mastering the rheology of self-compacting concrete (SCC) remains a major challenge for researchers. One of the main obstacles is segregation, an undesirable phenomenon where aggregates separate from the matrix, thus compromising the quality and homogeneity of the material. This study aims to use the ultrasonic pulse velocity (UPV) measurement technique

Testing of Concrete Structures with Non-Destructive Test Method (NDT) Using Ultrasonic Pulse Velocity (UPV) at the Building on the Ancol Beach

open access: yesCIVED
The UPV test procedure with the PUNDIT device is set based on the concept of the wave flow speed passing through a solid object bound to the elastic properties of a tangible medium. When used properly and correctly, this tool will provide a lot of information about the condition of the surface or the inside of the concrete.
