Sep 01, 2013 · Abstract The ultrasonic pulse velocity (UPV) in water-saturated concrete is higher than in dry concrete. However, moisture influence on the UPV is defined within a wide range: - from negligible to quite significant (16 per cent). The nature of "UPV − concrete moisture" correlation is also interpreted in different ways - both as linear and as exponential. This paper reviews how various ...
