|
Use to prepare a granular material for particle size analysis by removing fines that may impede the separation process. |
Wet sieving |
|
|
Involves flow of water through a relatively short soil sample connected to a stand pipe which provides the water head and allows measuring the volume of water passing through the sample. |
Falling head permeability test |
|
|
An apparatus used in constant head permeability test-- a specimen cylinders with diameter of 8 or 12 times Maximum particle size |
Permeameters |
|
|
Basically consists of placing an inflatable cylindrical probe in a predrilled hole and expanding this probe while measuring the changes in volume and pressure in the probe. |
Pressure meter test |
|
|
Give at least 1 apparatus used in pipette sampling |
Sampling Pipette, Mechanical shaker, 9 glass weighing bottles, test sieve, balance, sample devider, drying oven etc. |
|
|
This test is used to determine the undrained shear strength of soils especially soft clays. This can be done in laboratory or in a field directly on the ground? |
Vane Shear Test |
|
|
It is a rounded silica sands of nearly pure quartz used in sand replacement method. |

Surcharge Weights |
|
|
This method provides for the determination of a material at Optimum Water Content or a range of water content from a specified compaction test and specified dry unit mass. |
California Bearing Ratio Test |
|
|
Used for determination of specific gravity of soil particles of both fine grained and coarse grained soils? |
Pycnometer |
|
|
Defined as the moisture content after which any further reduction of moisture does not cause volume reduction? |
