Substation Grounding: Role of Crushed Rock
Crushed rock is useful in reducing step and touch potentials. Resistivity value of crushed rock depends on many factors such as type of locally available material, size of stone, washed vs un-washed stone etc. Washed rocks have less dust and has more resistivity compared to un-washed ones. Removing dust also aids in faster drying time after a rain.

Crushed rock dust as filler material in concrete
In India, it is estimated that out of 125 million tones (Mt) of stone aggregate produced every year, 17.8 Mt is crushed rock dust (CRD) which is presently used for land filling causing environmental problems such as loss of fertility of soil. This paper deals with the use of CRD as filler material in producing concrete.
