Perbedaan Hasil Uji Ultrasonic Pulse Velocity (UPV) Beton pada Mode Frekuensi Auto dan 50x
Indonesian Journal of LaboratoryABSTRACT.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 ...

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.With the growing need for sustainable building materials, the use of recycled materials in concrete production is encouraged. Reclaimed asphalt pavement (RAP) is a by‐product of road rehabilitation operations and is one possible substitute for natural aggregates (NAs) in concrete. In the case of RAP aggregates, however, the asphalt that has aged on the

The Journal of Engineering and Exact SciencesMastering 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
