First update on centrifuge testing

To carry out the first centrifuge tests a number of slabs were created by compressing material at optimum moisture content. The photos below show this procedure:

Mixed bentonite and sand at optimum moisture content after standing two weeks.

Material placed in the mould prior to static compression.

*Press setup.

Difficult to get compaction close to the stop blocks. We’ve cut off the first 40mm.

Pressed slab, that’s been cut.

First slab placed in the strongbox. Sidedrains visible. Slab is 150mm wide and 50mm thick. Covered by politrieen in the photo to reduce moisture loss.

Four slabs in the strongbox.
