Assessment of ultrasonic signals to determine the early age properties of concretes incorporating secondary cementitious materials

O'Connell, M. ; McNally, Ciaran ; Donohue, Shane ; Bonal, Julien ; Richardson, Mark G. (2009-09)

Secondary cementitious materials (SCMs) such as ground granulated blast-furnace slag (GGBS) are used in increasing quantities in concrete practice internationally. While these materials offer benefits such as reduced CO2 ...
Examination of a novel wavelet based approach for bender element testing

Bonal, Julien ; Donohue, Shane ; McNally, Ciaran (2008-12)

Accurate determination of shear wave arrival time using bender elements may be severely affected by a combination of near field effects and reflected waves. In most cases, the nearfield effect masks the first arrival and ...
Wavelet analysis of bender element signals

Bonal, Julien ; Donohue, Shane ; McNally, Ciaran (Institution of Civil Engineers/Thomas Telford Publishing, 2012-03-01)

Accurate determination of shear wave arrival time using bender elements may be severely affected by a combination of near field effects and reflected waves. These may mask the first arrival of the shear wave, making its ...
