Mixture Design of Concrete Using Ultrasonic Pulse Velocity
International Journal of Civil Engineering, 2019This article discusses the possibility of using ultrasonic pulse velocity (UPV) as a performance parameter for concrete design. Experimental values of UPV were determined for 68 mix design of concrete with different types of binders. Portland cements with fly ash, blast furnace and silica fume were investigated.

Concrete Quality Designation based on Ultrasonic Pulse Velocity
Construction and Building Materials, 2016Evaluating the condition of the original concrete of large structures built in the early twentieth century is an important part of safety review programs. However, in most large concrete structures, rehabilitation works have been carried out over the years, and only a limited number of cases have been well documented with regards to what has been done.

Measurement of velocity of propagation from ultrasonic pulse-echo data
Ultrasound in Medicine & Biology, 1982A method is proposed for determining velocity of propagation of ultrasound in tissue by processing the pulse-echo data obtained from a compound scan. Individual sectors from different transducer positions are reconstructed and a suitable area common to the two sectors is selected.

Acoustic emission and ultrasonic pulse velocity of concrete
International Journal of Cement Composites and Lightweight Concrete, 1982Abstract Both acoustic emission and ultrasonic pulse velocity measurements were used to try to monitor the structural integrity of concrete. Specimens in the form of 150 mm cubes were loaded monotonically to failure, and acoustic emission and ultrasonic pulse velocity were measured simultaneously.

Prediction of Pavement Materials' Impedance Using Ultrasonic Pulse Velocity
Road Materials and Pavement Design, 2009ABSTRACT There are many factors that influence tire/pavement noise such as road friction and acoustic absorption as well as pavement texture. Highway noise is addressed through several models such as Traffic Noise Model (TNM) developed by the Federal Highway Administration (FHWA) of the United States.

Modifications to Standard Pulse Techniques for Ultrasonic Velocity Measurements
The Journal of the Acoustical Society of America, 1959A description is given of modifications to the “sing-around” and coincidence techniques for velocity measurement. In the case of the “sing-around” method a gate is incorporated which effectively lengthens the ultrasonic path by allowing retriggering on multiply reflected pulses. This allows the use of short solid specimens having low attenuation.

Image matching for pulse echo measurement of ultrasonic velocity
Image and Vision Computing, 1983Abstract Diagnostic ultrasound is a pulse echo imaging system similar to radar, sonar or exploration seismology. It has its most widespread use in the examination of pregnancy, but also finds routine use in the examination of the organs of the upper abdomen and its use is increasing in other areas. Using current techniques the information obtained is

Studies in ultrasonic pulse velocity of concrete containing GGBFS
Construction and Building Materials, 2013Abstract This paper presents the results of experimental investigations into the time-dependent ultrasonic pulse velocity (UPV) of concrete containing GGBFS. The UPV was determined at the age of 3, 7, 28, 56, 90, 150 and 180 days for twelve concrete mixes using the prism specimens of plain and GGBFS concrete.

Implementation of a novel pulsed ultrasonic Doppler velocity profiler
SPIE Proceedings, 2003The objective of the work is to apply advanced digital signal processing (DSP) and pulsed Doppler echography techniques to analyze velocity profile of the measured fluid in a closed full-pipe. In order to reliably measure velocity profile where non-intrusive ultrasonic Doppler velocity profilers (UDVPs) cannot properly transmit and receive ultrasonic ...

Evaluation of Clay Brick Durability Using Ultrasonic Pulse Velocity
Journal of Architectural Engineering, 1998Many failures in the building envelope are associated with disintegration of the brick veneer. The evaluation of durability is important for proper selection of the brick. The American and the Canadian standard methods for evaluating the durability of brick are time consuming and involve destructive testing.
