CORRELATIONS BETWEEN INDEX TESTS AND THE PROPERTIES OF REMOULDED CLAYS

Correlations have been developed which relate the compressibility, undrained shear strength, and permeability of remoulded clays to their Atterberg limits and activity. The relationships can be used to model a hydraulic fill, such as fine-grained dredged material or mine tailings, prior to deposition. They can also be used to estimate the engineering properties of normally consolidated natural clay, such as marine sediments. The correlations cover a wide range of plasticity index and liquidity index for a wide variety of clays. It was found that the activity plays a major role in the compressibility and undrained shear strength, and is thus also related to the sensitivity of clays. The activity apparently does not affect the permeability, but other factors remain to be investigated. Because compressibility, undrained shear strength, and permeability are interrelated, it can be concluded that if one is known, then the other two can be derived. Hence, these three engineering properties are seen as different expressions of the same physical phenomenon, rather than as independent variables. (Author/TRRL)
