This is for determining the moisture density relation of soils.

In this apparatus, small quantity sample is compacted undez kneading action of the spring loaded tamper set either at 10kg or 20kg.

As the sample required is very small, a number of tests can be carried out, each time taking a fresh sample.

The time required for compaction is very much less.

The mould can be inter changeably used with Miniature Field permeameter where permeability tests can be conducted at high pressures.
