Abstract

IT has been realized for some time that plate-shaped clay particles on drying tend to take up a parallel orientation with respect to one another. Further, Terzaghi1 has indicated that groups of parallel particles behave as a single particle in suspension and has referred to these groups as ‘clay clusters’. Aylmore and Quirk2, in endeavouring to interpret the swelling of clay-water systems, have defined a ‘domain’ as a parallel arrangement of crystals. Coal research workers3 have referred to a similar type of organization as ‘turbostratic groups’ since the elementary particles are arranged in a parallel fashion in groups and these groups are arranged in turbulent array. The present communication presents evidence for the nature of a domain and discusses the consequence of domain formation in swelling phenomena of clays.
