Liquefaction of Silts and Silt-Clay Mixtures

Journal of Geotechnical and Geoenvironmental Engineering, 1999
Low plasticity silts and silty clays occur extensively in the central United States. For evaluating their liquefaction potential during an earthquake, no guidelines are available based on their density, void ratio, plasticity index, standard penetration values, or any other simple soil property. Their liquefaction behavior is not properly understood at

Synthesis of Ultramarine from Reservoir Silts

Minerals (Basel, Switzerland), 2017
Ultramarine blue was synthesized by using reservoir silts as a major raw material to replace traditional kaolin clay. The reservoir silts were pretreated to collect the fines, in which the main mineral composition is illite clay.

Liquefaction of low plasticity silts

Soil Dynamics and Earthquake Engineering, 1992
The influence of plasticity index on the liquefaction potential of silty soil of low plasticity (PI of 1·7 to 3·4) has been studied in detail. The change in plasticity index was achieved by mixing the low plasticity silt with 5 and 10% by weight of ...
