Determining the Essential Qualities of Sand: 6 Tests

(c) Dry permeability is the permeability measured in a specimen made of moulding sand and dried at about 100 to 110°C. (d) Baked permeability is the permeability measured in a specimen made of sand with thermo-setting binder and backed at some temperature above 105°C. Permeability test is carried out by using a permeability meter consisting .

Permeability Test of Soil by Falling, Constant Head

The constant head permeability test is usually preferred for sandy soils and the variable head permeability test for silty and clayey soils. A separate constant head method for granular soils has been recommended by Indian Standards (IS: 2720 – Part 36, 1975).
