Abstract

An apparatus is provided. The apparatus is provided for interacting with a cylindrically-shaped construction material sample that defines a longitudinal axis extending from a central point of an end of the construction material sample. The apparatus includes a translation mechanism configured for rotating the construction material sample about the longitudinal axis and at least one material-interacting device spaced-apart from the translation mechanism and configured for interacting with the construction material sample.
