Tseung Kwan O Area 137 Fill Bank Adobe Mud Brick 2
Soil / Soil based (organic/mineral)
25 Jul 2023 (Produced)
This soil was designated as public fill within the Tseung Kwan O Area 137 Fill Bank.
Basic on site testing determined that the clay content was sufficient for making activities. A large sample of fill was transported to the University of Hong Kong Division of Landscape Architecture, where soil processing is underway.
No additives were added to the soil. This brick was part of an experiment to see which soils performed better with an addition of 30% water. The soil was sieved through a fine sieve resulting in smaller overall particle size. Wetted the mold and brick would not come out of the mold, did not wait long enough between filling the mold and immediately trying to take it off. The brick would not come out of the mold, flipped mold over and had to press down on the soil while pulling mold off. Because of this the brick is not straight and is very deformed. In the future must figure out a better way of either coating the mold or different ratio of water.
