Can anybody let me know the composition of backfill compound used in earthing electrode.
The resistivity of backfill should be 0.12 Ohm-Mts, envoinmental friendly.

Wet dirt is just fine. If the resistivity is too high on testing, the following can be done:
Extend the electrode futher into the ground
Increase the number of electrodes
Add mineral to the ground - whatever can be found: seawater, urine, etc.
