There are quite a number of factors that influence the static and cyclic liquefaction phenomenon of a geomaterial (tailings or soil) such as confining pressure, initial void ratio, initial stress condition, amount and content of fines, sample preparation method, over consolidation ratio, length of time under sustained pressure etc. Also, authors such as Gratchev et al. (2006) and many others have carried out a series of tests using plasticity index as a benchmark for assessing cyclic behaviour of soil, however, the plasticity index still does not fully capture the whole factors that influence the soil strength under cyclic stress. I would like to know the influence of chemistry on the liquefaction of both montmorillonite and kaoline clay tailings.
so you are looking for effects on dynamic / cyclic liquefaction, not static, as observed in very loosely packed saturated fine sands.
As you want to know the chemistry on liquefaction of both montmorillonite and kaoline clay tailings. So try to understand the cyclic behavior of clayey soil which is mainly composed of montmorillonite and kaoline and also the effect of water on these types of soils.
Thank you very much Dick R. Mastbergen . I'm actually very interested in the chemistry influence on both static and dynamic liquefaction.
I think that chemistry is affected in the liquifaction phenomenon in cases of cohesive soils only, such as clay, etc. It is not affected in non-cohesive soils such as sand.
