PURPOSE : An earth resistance decreaser and composition thereof are provided to show workability for installing the earth resistance decreaser and prevent corrosion and erosion of earth bars.CONSTITUTION : A composition of earth resistance decreaser comprises 10-15wt%% of soil, 50-60wt%% of briquette ash, 5-10wt%% of water, 15-20wt%% of earthron and 10-15wt%% of conductive filler. The soil and briquette ash contain clay components and silicon dioxide. The conductive filler includes metal powder or carbon powder. The particle size of the metal powder or carbon powder is 0.5 ~ 2μm. The earth resistance decreaser is produced by mixing compositions, forming stamping materials and molding the stamping materials.© KIPO 2009
