Table 4: Shrinkage level (a: axial, r: radial, t: tangential) for different samples of waterlogged wood not impregnated, thermally treated (TT), dried with different techniques:
- Dried by hot air (SAC - temperature °C) - Dried by continuous vacuum (SVC - temperature °C) - Dried by DDS (DDS - maximum pressure in bar).
