Determination of shrinkage limit of soil
WebThe plastic limit of a soil is the moisture content at which soil begins to behave as a plastic material. At this water content (plastic limit), the soil will crumble when rolled into threads of 3.2mm (1/8in) in diameter. In this article test methods used for determination of soil plastic limit in accordance with ASTM D4148 will be presented. WebFor friable soils, the SL may be anywhere between the LL and 50 per Cent of the LL, and for feebly plastic, 25 to 30 per cent ; for medium plastic, 20 to 25 per cent ; for highly plastic, 15 to 20 per cent. There is no definite relation between the Plastic Limit and the …

WebApr 1, 2011 · Shrinkage limit of fine-grained soils is one of the parameters that is used for predicting the volume stability of soils in the field. ASTM Standard D427-04 (2007) involves the use of mercury, a ... The Atterberg limits are a basic measure of the critical water contents of a fine-grained soil: its shrinkage limit, plastic limit, and liquid limit. Depending on its water content, soil may appear in one of four states: solid, semi-solid, plastic and liquid. In each state, the consistency and behavior of soil are different, and consequently so are its engineering properties. Thus, the boundary between each state can be defined based on a cha…

WebThe water content at which the soils change from one state to the other is known as consistency limits or Atterberg limit. The liquid state is the state of a fine-grained soil at which the soil will flow on its own weight.
