Aug 15, 2017 Knead the soil for a few minutes to reduce its water content slightly. Repeat steps 2 to 5 until the thread crumbles when it reaches a uniform diameter of 1/8 in. When the soil reaches the point where it will crumble, and when the thread is a uniform diameter of 1/8, it is at its plastic limit. Determine the water content of the soil.

Figure (a) shows a soil sample which is fully saturated and has the water content greater than the expected shrinkage limit. In figure (b), the soil sample is at shrinkage limit. Finally, figure (c) depicts the condition when the soil sample has been oven-dried. Hence, the total volume in third figure is the same as the volume in second case.

Atterberg Limits Test What is the Purpose? - Gilson Co.

Soil mechanics tests in geotechnical laboratories measure particle size distribution, shear strength, moisture content, and the potential for expansion or shrinkage of cohesive soils. Atterberg limits tests establish the moisture contents at which fine-grained clay and silt soils transition between solid, semi-solid, plastic, and liquid states.

Specific gravity is a dimensionless quantity that is defined as the ratio of the weight of oven-dried aggregates to the weight of a volume of pure water displaced by an equal volume of saturated surface dry aggregates. An oven-dry condition of aggregate is obtained by drying the aggregates in the oven for 24 hours at 100C -110C.

Water content - Wikipedia

Water content - Wikipedia

Water content or moisture content is the quantity of water contained in a material, such as soil (called soil moisture), rock, ceramics, crops, or wood.Water content is used in a wide range of scientific and technical areas, and is expressed as a ratio, which can range from 0 (completely dry) to the value of the materials' porosity at saturation. It can be given on a volumetric or …
