Ultrasonic wave propagation in thermally treated concrete up to 400 ºC
The ultrasonic pulse velocity, obtained by ultrasonic non-destructive testing, has been applied to evaluate the concrete integrity. The attenuation parameters have shown more sensitivity to damage detection in the microstructure of concrete since they ...

Assessment of concrete compressive strength by ultrasonic pulse velocity test
One of the most popular non-destructive techniques is ultrasonic pulse velocity (UPV) which used in assessment of concrete properties. A statistical experimental program was carried out in the present study to establish an accurate relation between the ...

Dimension Effect on the Ultrasonic Pulse Velocity
Ultrasonic pulse velocity test is non-destructive and relatively simple to carry out at both in-situ and laboratory conditions. The sonic velocity (SV) test has been used to determine the dynamic properties of rocks in different applications of rock and geotechnical engineering.

Prediction of cemented backfill strength by ultrasonic pulse velocity and BP neural network
Tailing-cemented backfill is a cement-based heterogeneous composite whose uniaxial compressive strength (UCS) and ultrasonic pulse velocity (UPV) are dependent on cement dosage, solid content, sample type, etc.

The study of ultrasonic pulse velocity on plain and reinforced damaged concrete
An ultrasonic pulse velocity (UPV) test is often applied to determine the quality of concrete structures. It is well known that there are several factors which can influence the reading of ultrasonic velocity in concrete.

Application of ultrasonic pulse velocity technique and image analysis in monitoring of the sintering process [PDF]
Concrete which undergoes a thermal treatment before and during its life-service can be applied in plants operating at high temperature and as thermal insulation. Sintering occurs within a concrete structure in such conditions. Progression of sintering

Evaluate Brick Units by Ultrasonic Waves
Wide laboratory search was done to evaluate brick units in single, and test the prisms built from brick unit by use ultrasonic waves in non-destructive test. The results show that the pulse velocity increases with increasing compressive strength and time

Investigation of Concrete Segregation by Ultrasonic Pulse Velocity
Segregation is the separation of the components of fresh concrete or mortar, which can be caused by bad proportioning, insufficient mixing or excessive vibration. There are several tests which can be measured on hardened concrete or at the beginning of hardening. These are generally based on the percentage of the Fine aggregates between the top and the
