AbstractTwo series of compacts are studied, one d-dried before and one after compaction. Measurements of absolute density, helium flow characteristics and Young's modulus indicate that high pressures can force the layers of d-dried material closer together, giving a Young's modulus double that displayed when no interlayer water is present and identical to that when spaces are occupied by water molecules. Water can re-enter between the layers, however, and on redrying Young's modulus is reduced by 50 per cent to the normal value for the d-dried material. The interlayer water must be regarded as part of the solid.
