Abstract
The title of this chapter was chosen for two reasons. Solid particles can stick together by net attraction (Sect.7.1), and similarly by capillary (Sect. 7.2) or solid bridges (Sect. 7.3), this attraction enables macropores. In spite of higher skeleton pressures the limit void ratios can be higher by net attraction. The influence and evolution of particle bridges can be captured by extended constitutive models, these will but briefly be indicated as there are only few validations.
