Abstract
Providing a grounding resistance reducing material that can contribute to the reduction in carbon dioxide emission and can be used in the same manner as the grounding resistance reducing material that uses coke, which is fossil fuel, and a grounding device using the grounding resistance reducing material, and also providing a grounding resistance reducing material whose weight can be trimmed. A grounding resistance reducing material 14 to be laid between a grounding electrode 11 buried in soil 12 and the soil 12 contains carbide granules obtained by incomplete combustion of biomass.
Claims9
A grounding resistance reducing material to be laid between a grounding electrode buried in soil and the soil, consisting of carbide granules obtained from incomplete combustion of woody biomass, wherein
- the specific resistance of the carbide granules is 430 Ω·cm or lower,
- the carbide granules and a hydraulic powder are mixed at a ratio by weight in a range from 10:90 to 50:50,
- the carbide granules and the hydraulic powder are contained in a mixed state, and
- the grounding electrode can be integrated as hardening progresses.
