An instrument for measuring certain physical properties of a sample of particulate material so that the flow characteristics of the material can be determined includes an improved compaction assembly having an upper piston (30) that is surrounded by a retractable sleeve (22) and further includes an improved test cell (40) having cylindrical walls (54), having a failure outlet smaller than the diameter of the failure piston (30), and having a false bottom (58) that can easily be removed from beneath a sample of compacted material to permit the failure portion of the test to be carried out. The tester can be used for determining the confined yield strength of the material, its bulk density, and its permeability.

La présente invention se rapporte à un appareil servant à mesurer certaines propriétés physiques d'un échantillon de matière particulaire en vue d'en déterminer les caractéristiques d'écoulement; celui-ci comporte une dispositif de compactage constitué d'un piston supérieur (30) entouré d'un manchon rétractable (22) et comportant une cellule d'essai améliorée (40) constituée de parois cylindriques (54) recelant un orifice de rupture de diamètre inférieur à celui du piston supérieur (30), ainsi qu'un faux fond (58) qui peut être facilement retiré sous un échantillon de matière compactée afin de permettre la conduite de l'essai de rupture. L'appareil en question peut être utilisé pour déterminer la limite d'élasticité en compression du matériau, sa masse volumique en vrac ainsi que sa perméabilité.
