Used for determining the relationship between the moisture content and density of compacted soil. The mould includes collar, mould body and base plate. Steel plates may be used at the end of compaction on top of last layer (optional). The rammer construction includes a guide sleeve with vent holes.
Different versions are available that conform to the various commonly used standards. They are all made of plated steel and are identical in shape, only differing slightly in diameter and capacity.
In this section moulds and rammers conforming to EN are shown.
For the extrusion of soil specimens from the mould, the Universal specimen extruder may be used, see Link to other products below.
An alternative (and preferable) method of compacting is to use an automatic compactor.
