THE PLASTICITY INDEX OF INORGANIC CLAY

open access: yes, 2023
This paper presents a model that can be used to compute the plasticity index of inorganic soil using the correlation between the liquid limit and the plasticity index. The model was developed using British fall cone Atterberg limit test results using 120

Sensory trait variation in an echolocating bat suggests roles for both selection and plasticity [PDF]

open access: yes, 2014
Background: Across heterogeneous environments selection and gene flow interact to influence the rate and extent of adaptive trait evolution. This complex relationship is further influenced by the rarely considered role of phenotypic plasticity in the ...

Discussion: Remoulded shear strength at plastic and semi-solid states [PDF]

open access: yes, 2013
The undrained shear strength of remoulded soils is of great concern in geotechnical engineering applications. This study aims to develop a reliable approach for determining the undrained shear strength of remoulded fine-grained soils, through the use of ...

Flow index-liquid limit relationship by fall-cone tests in clay-sand mixtures

open access: yesEngineering Science and Technology, an International Journal, 2023
The Fall-cone test is a useful method which can be used in evaluation of many soil index and strength identifiers. In this regard, the flow index is calculated as the slope of the plot of water content against natural logarithm of the penetration depth ...
