TKO Clay 02/Bentonite (4:1) Pressed Brick

This set of bricks were part of an experiment to determine the amount of bentonite (23-1000-349-e) to add to a clay-y soil (23-1000-349-d). This soil mixture was then evaluated on how it performed when compressed within the brick press. Water was added to the point that the soil mixtures were between the 'plastic' and 'humid' range.

Notes: Soil mixture was more humid. The bentonite sample was crushed by hand and added to the roughly sieved clay, this was then mixed by hand in a bucket and then further mixed on the tarp. Have noticed that there are inconsistencies in the heights of the bricks, believe this is due to the initial pore space of the soil within the brick press, this could vary the actual volume of soil that is being pressed resulting in varied heights.

Soil Additives: Tseung Kwan O Area 137 Fill Bank Clay 02 (23-1000-349-d) and Tseung Kwan O Area 137 Fill Bank Bentonite Clay (23-1000-349-e)

Ratio of Soil Additives: Clay : Bentonite 4:1
