Now place the sand cone on the test hole with the help of the base plate and allow the sand to run by opening the control valve. 5. When the sand stops running, close the valve and weight the cone with the existing sand. Finally, calculate the dry density of the soil by given below formula. If the test fails, compact and perform the test again.

Evaluation of the sand-cone method for determination of,

A sand-cone method is commonly used to determine the density of compacted soils. The density of the compacted soil calculated from the sand-cone method could be correct, provided the calibration container has approximately the same size or volume and allows the sand to fall to approximately the same height as a test hole in the field.,,
