| Summary: | 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.
