Studies in ultrasonic pulse velocity of concrete containing GGBFS

Construction and Building Materials, 2013
Abstract 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.

Prediction and sensitivity analysis of compressive strength in segregated lightweight concrete based on artificial neural network using ultrasonic pulse velocity

Construction and Building Materials, 2018
Due to the low density of the aggregates used, lightweight aggregate concrete (LWAC) is susceptible to segregation because of the differences between the densities of their components.

Modifications to Standard Pulse Techniques for Ultrasonic Velocity Measurements

The Journal of the Acoustical Society of America, 1959
A 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.
