Low resistance earthing compound and its placement
专利汇可以提供Low resistance earthing compound and its placement专利检索，专利查询，专利分析的服务。并且PURPOSE: To place a low resistance earthing compound having an early setting property and a high solidification trength by the procedure in which a precast low resistance earthing compound of a specific composition containing a conductive chemical, water, Portland cement, and sodium silicate as a high early-strength chemical is laid underground and then an earth bar is struck into the earthing compound.
CONSTITUTION: A low resistance earthing compound is first prepared by mixing sodium silicate (1.0 in wt ratio), Potland cement (more than 4.0), water (more than 13.0), and a conductive chemical (more than 0.25), e.g., sodium chloride, carbon powder, bentonite, etc., and then the low resistance earthing compound so prepared is precast into a predetermined dimension of moldings. The precast moldings are delivered to a construction site in case it is used and then is laid underground at an earthing position without any mixing operation at site being carried out. And, the earth bar is struck into the earthing cmpound molding laid, thus simplifying the earthing operation
