Jan 09, 2020 Determination of Water Content of Soil by Oven Drying Method. The soil samples collected from top soil (Luvisol), 30 cm of depth, were analyzed for water content (W n, %) with the oven method and Speedy Moisture Tester in the laboratory. 40 g soil is taken at each of measuring points. 20 g of this was used in the oven method and 20 g in the ...

Jul 06, 2020 The water content of materials contains extraneous materials that may require special treatment for the removal of these substances. The oven-dry method helps to decompose some organic materials at a standard temperature of 110 o C. Water Content. It is defined as the ratio of the weight of water to the weight of solids present in the soil sample.

Jul 13, 2017 The water-content determination is a routine laboratory procedure. ASTM has designeated it with a Standard, ASTM D-2216-90 which can be found in “ASTM Standards vol. 4.08”, and also AASHTO T-265, found under “AASHTO Materials: Part II: Tests”.
