The difference between core cutter method and sand replacement method is that in core cutter method density of soft soils like clay soil or other cohesive soils which are placed as fills are determined while in sand replacement method, a small pit is made and the soil that is excavated is weighed. Why is field density important?

6. procedure i) Calibration 1) Fill the sand-pouring cylinder with sand, within about 10mm of its top. Determine the mass of the cylinder (M1) to the nearest gram. 2) Place the sand-pouring cylinder vertically on the calibrating container. Open the shutter to allow the sand run out from the cylinder.

1) Core cutter method: It is a field method, suitable for soft and fine-grained clayey soil. Not suitable for Stoney, gravely soil, and dry soil. 2) Sand replacement method: Used for gravelly, sand, and dry soil. 3) Water replacement method: Suitable for cohesive soil only and paraffin wax is used in it. 4) Rubber ballon method:

Open the shutter and permit the sand to run into the hole. Close the shutter when no further movement of the sand is seen. Remove the cylinder and determine its weight (W3). Moisture meter Dry density Step 2. Expose an area of about 450mm square on the surface of the soil mass. Trim the surface down to a level surface using a scrapper tool.

The test consists in digging a hole into the ground and then collect, dry and weight the sampled soil. The hole is now filled with dry sand from the cone container and the volume of sand recorded. Three versions are available Ø 4" 6.5" 12" each one suitable for different grain sized. The S231KIT model Ø 12" is recommended for coarse grained soil

STEP 7 - To find the conical heap of sand weight, place the sand pouring cylinder on the glass plate & open the slit hole to allow sand to fall on the glass plate in a conical heap. Once the sand fall has over, close the slit & remove the cylinder. STEP 8 - Now weight the sand in conical shape as on the glass plate as W3.

For soils, such as hard soil or granular soil, where core cutter method cannot be applied, sand replacement method is used for the determination of unit weight of soil in its natural state. For this test to perform we will be needing a calibrating sand which passes through 1 mm IS sieve and retained on 600 micron IS sieve.
