Soil Compaction Cylinder

A metallic device for compacting soil and soil-cement specimens for tests, such as moisture-density and durability tests. It consists of a cylindrical mold in which the specimens are compacted, a detachable collar, or extension, and a detachable base to which the mold and collar assembly is fastened. The mold bore may be either straight or tapered and the mold wall either solid (continuous) or split, the taper bore and the split wall facilitating the removal of the specimen. Internal dimensions are machined to close tolerances to insure volumetric accuracy.
