A newly developed ultrasound method that acquires at the same time both reflected and transmitted P-waves, different angles, using two immersion transducers of 0.5 MHz central frequency, is described in this present study. This non-destructive allows calculating longitudinal transverse velocities, thus, Young modulus, so its evolutions followed domain. The closely correlation between evolution domain those calculated parameters hydration properties cement based materials was used to...
Presently, the quantification of water content in ultra high temperature (UHT) processed milk predominantly relies on destructive methods such as pH and conductivity measurements.These methodologies, while effective, are time-consuming necessitate specific experiential knowledge.This study delineates a non-destructive alternative employing ultrasound technology for monitoring UHT milk.The interplay between electrical was scrutinized juxtaposed with measurements.Ultrasound parameters,...
In this study, the effects of alkaline accelerating admixture and its dosage on cementitious material's behavior at early ages were evaluated through a series ultrasound Pulse echo measurements.Thus, those measurements consist following evolution frequency dependent attenuation coefficient during material age.Four stages can be identified vs. mortar age graphs, indicating that development parameter is closely related to setting hardening phenomena.Also, histograms, representing different...
This paper aims to characterize the effects of natural clay additions in mortar mixes different concentrations and under curing temperatures on setting hardening cement mortar.For this purpose, characterization technique based reflection ultrasounds was used.Using technique, attenuation coefficient modulus are measured early age hydration behavior tested cement-mortars.Ultrasound P-waves were generated using a 1 MHz central frequency immersion transducer samples prepared with Portland...
