Flow index in soil mechanics

WebPlasticity Index (Ip) Plasticity Index is range of consistency in which soil exhibits plastic properties or behaves like plastic materials. It is defined numerical difference of liquid limit and plastic limit. \(Ip = w_L-w_p\). Liquid limit, Plastic limit, and Plasticity index are all dependent upon type & amount of clay mineral. WebFeb 28, 2024 · Choose. Vardanega et al. (2024) proposed a new plasticity chart for soil classification using flow index and fall-cone liquid limit as measured from fall-cone tests. The new plasticity chart is of great significance as it allows soil classification to be performed without thread-rolling tests, which may well introduce the operator's influence.
