Oyster Debris Brick (crushed oyster)

Oyster shells and debris for this material test series were collected from 'The Nature Conservancy' (TNC) under its oyster recycling project. The oyster shells are placed in a mould and filled with a mix of cement/sand/oyster debris. After curing, the brick is sliced into a series of thin slabs using a water jet. The 15mm thick slabs are richly textured, revealing oyster aggregates of different sizes as well as a riffled surface from the water jet cutting.
