5 p, 105.0 KB Correlation between surface area and Atterberg limits of fine-grained soils / Dolinar, Bojana (University of Maribor. Faculty of Civil Engineering) ; Mišič, Miha (Geological Survey of Slovenia) ; Trauner, Ludvik (University of Maribor. Faculty of Civil Engineering)
As the water content is increased, the consistency of a fine-grained soil changes from a semi-solid state to a plastic state and finally to a liquid state. The plastic limit (PL) is the point at which the consistency, caused by the soil water content, is transformed from a semi-solid state to a plastic state. [...]
