  • Nedknusing av bergartsfragmenter og mineralkorn ved bretransport Crushing of rock fragments and mineral grains by glacial transport
  • The crushing of mineral material and the formation of resistant mineral modes during the glacial transport are mainly dependant on the primary properties of the mineral material, inherited from the parent rock. This is illustrated
  • The crushing test on soil aggregates of irregular shape is calibrated against the Brazilian test for cylinders. Factors affecting the strength of soil aggregates are reviewed. These include water content, wetting and drying cycles, and age hardening
  • Field enquiries and measurements of soil resistance to crushing in different parts of Belgium have shown that : (a) hydromorphic and slightly stony silty soils are most sensitive to damages due to skidding machines, (b) this sensitivity is mainly
  • a wide range of silt and boulder sizes. Crushing into smaller pieces, rather than the removal of asperities is postulated as the dominant process of glacial erosion. Sediment loads are given for the glacial streams.
