Abstract
The consolidation of paper during drying is of interest to increase the understanding of the development of the paper quality. The mercury displacement technique proved suitable to measure the apparent solid density and the volume fractions of solid, liquid and gas in wet paper sheets. Measurements were performed on handsheets of chemi-thermomechanical pulp (CTMP), bleached and unbleached softwood kraft and bleached hardwood kraft. The measured apparent solid density and volume fractions were independent of the basis weight in the range of 100-250 g/m<sup>2</sup> . This investigation shows that pressing, refining and bleaching do not change the consolidation of the sheets fundamentally
