Clean and level the place where density is to be determined.
Drive the core cutter, with a steel dolly on its top, into the soil to its full depth with the help of a steel rammer.
Excavate the soil around the cutter with a crow bar and gently lift the cutter without disturbing the soil in it.
Trim the top and bottom surfaces of the sample and clean the outside surface of the cutter.
Weigh the core cutter with soil (W2)
Remove the soil from the core cutter, using a sample ejector and take representative soil sample from it to determine the moisture content.

Description

Technical Specification:-

Determine the internal diameter and height of the core cutter to the nearest 0.25mm
Determine the mass (M1) of the cutter to the nearest gram.
Now an exposed area of 300 sq. mm is taken where the field density is to be determined and level the surface.
After leveling the surface place the dolley over the top of the core cutter and press the core cutter vertically down the soil mass using the rammer.
Continue pressing when about 15mm of the dolley protrudes above the soil surface.
25 mm high and 100 mm internal dia with a wall thickness of 7.5 mm with a lip to enable it to be fitted on top of the core cutter.
A solid mild steel foot of 140 mm diameter and 75 mm height with a concentrically screwed 25 mm dia. Solid mild steel staff.
The overall height of the rammer including the foot.
A blade of stainless steel approximately 200 mm long & 30 mm wide (Stainless steel spatula ).
A steel strip about 300 mm long, 25 mm wid& 3 to 5 mm thick with one bevelled edge with suitable to level off ground.
Weigh the core cutter filled with the soil to the nearest gram (M2).
Now remove the core of the soil from the cutter. Take a representative sample for the water content determination.

Accessories:-

Cylindrical core cutter 100mm i.d. x 175mm long
Dolly
Test form pad of 50.
