Mean grain size determination in marbles by ultrasonic velocity techniques

Grain size determinations by various ultrasonic techniques have been considered by several researches. In this paper, we have studied mean grain size determination of some marbles by using ultrasonic velocity measurements. We have represented ultrasonic velocity-grain size size master graph. Using this graph, we have compared mean grain size of marble samples by optic microscope images. (C) 2004 Elsevier Ltd. All rights reserved.
