Using Support Vector Machine to Improve Ultrasonic Pulse Velocity Test for Concrete
MATEC Web of Conferences, 2018 In the construction industry, to evaluate the compressive strength of concrete, destructive and non-destructive testing methods are used. Non-destructive testing methods are preferable due to the fact that those methods do not destroy concrete samples ...

Dimension Effect on the Ultrasonic Pulse Velocity
International Journal of Geography and Geology, 2017 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.

The study of ultrasonic pulse velocity on plain and reinforced damaged concrete
MATEC Web of Conferences, 2018 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.

Prediction of cemented backfill strength by ultrasonic pulse velocity and BP neural network
工程科学学报, 2016 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.

Application of ultrasonic pulse velocity technique and image analysis in monitoring of the sintering process [PDF]
Science of Sintering, 2011 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
