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.
Get DetailsGs = Unit weight (or density) of soil sample only / Unit weight (or density) or water . The general values for specific gravity for different soils are given in Table -1. This method of determining the specific gravity of soil is given here is applicable for soils composed of particles smaller than 4.75 mm (No.4 U.S. sieve) in size.
Get DetailsInitial water content of wet soil can be derived as – ASTM D-4943 describes a method of using molten wax for the determination of shrinkage limit in place of mercury, since handling mercury is hazardous. In this method, the oven-dried soil pat is dipped in molten wax. The wax-coated soil pat is then cooled.
Get DetailsSep 20, 2002 (1) Calculate the water content of each of the liquid limit moisture cans after they have been in the oven for at least 16 hours. (2) Plot the number of drops, N, (on the log scale) versus the water content (w). Draw the best-fit straight line through the plotted points and determine the liquid limit (LL) as the water content at 25 drops.

Get Detailssometimes used instead of water content. A saturated soil has its voids completely filled with water, and its water content is denoted by w,,. Soil below the water table is usually considered to be saturated. Dry soil contains only air in the voids. Drying a soil to a constant weight in an oven at a temperature of 1 10 L 5 C is D the ...
Get DetailsThe method described herein is based upon AASHTO Designation T89 which has been modified for New York State Department of Transportation use. 2. DEFINITION 2.1 The liquid limit of a soil is the moisture content, expressed as a percentage of the weight of the oven-dried soil, at the boundary between the liquid and plastic states of consistency.
Get Detailswater content and dry soil weight: a. Mix sample thoroughly in the bag by kneading it with your fingers. b. Take a 1/8-cup level scoop of loose soil (not packed down) from plastic bag and place it in the cup weighed in step 7 (use more than one scoop to increase accuracy). 9. Weigh moist e subsamplin cup before drying and record in table 2. 10.
Get DetailsWater content required to attain field capacity of soil = 30-10 = 20% i.e. 0.20 cm of water per cm of soil depth. Therefore, rainfall of 10 cm will wet the soil to a depth of
Get DetailsWater content The most usual method of determining the water content of soil is to weigh a small representative specimen, drying it to constant weight and then weighing it again. Drying can be carried out using an electric oven set at 104-105 Celsius or using a microwave oven.
