碩士 === 國立成功大學 === 電機工程學系 === 89 === The granulated blast furnace slag is waste of the by-products of steel-making plant. It mostly applies in civil engineering、build engineering and build road now, it will be the major task of the environmentalism from now on that the granulated blast furnace slag is reclaimed in other domain. The characters of low resistivity and glue about the granulated blast furnace slag, can product glue under cement-hydrate catalyst, and it should be material of the grounding resistance reduction. This paper discuss the granulated blast furnace slag of main material of the grounding resistance reduction. According to the additives of the differnet proportion of water、cement and salt, its resistivity and clot strength are considered, the optimum combination is sought out. The finished product can be used in the grounding resistance reduction. And the grounding bar is buried in it, The proposed method is testified that achieve the purpose of reducing the grounding resistance effectively by measurement result.
