Abstract:

The complex shear modulus of both kaolin-water and bentonite-water mixtures has been determined in the laboratory. The method involved measuring the reaction on a torsional elastic wave propagated down a metal rod when the rod was immersed in sediment. Observations were made over the frequency range two to forty-three kHz. Dispersed sediments behaved like Newtonian liquids. Undispersed sediments, however, were viscoelastic in character, and their shear moduli exhibited no dependence on frequency. For undispersed kaolin mixtures, a typical result is 21.6 i 1.2 x 1,000 dynes per square centimeter at 32 percent concentration. In bentonite, a modulus of 4.6 i 2.0 x 10,000 dynes per square centimeter at 19 percent concentration is representative. Author
