minus-squarectenidium@lemmy.worldlinkfedilinkarrow-up2·2 months agoThank you very much for this elaborate explanation! I was even aware of that clay part, since I know the grain size distribution “triangle”? I don’t know, what this could be in English.
minus-squareTrack_Shovel@slrpnk.netOPMlinkfedilinkEnglisharrow-up3·2 months agoYou’re referring to the texture triangle. But yes, all textures are just different ratios of the size fractions (sand 2 mm to 0.05 mm, silt 0.05 mm to 0.002 mm, clay <0.002 mm). Not all clays will swell - kaolinite is a 1:1 clay for instance but 2:1 clays like montmorillonite will hydrate and swell to a greater degree.
