- The Fines Fraction Of A Soil To Be Used For A Highway Fill Was Subjected To A Hydrometer Analysis By Placing 20 Grams Of 1 (23.01 KiB) Viewed 10 times
The fines fraction of a soil to be used for a highway fill was subjected to a hydrometer analysis by placing 20 grams of dry fines in a 1 liter solution of water (dynamic viscosity 0.01 Poise at 20 degrees centigrade). The specific gravity of the solids was 2.65. a) Estimate the maximum diameter D of the particles found at a depth of 5 cm after a sedimentation time of 4 hours has elapsed, if the solution's concentration has reduced to 2 grams/ liter at the level. At that moment, b) What percentage of the sample would have a diameter smaller than D? c) What type of soil is this?
