Abstract :
One by-product of steel making, granulated blast furnace slag, is often wasted. When it is used, it is used in civil engineering and building engineering and mostly applied to road-building. It will soon have many other environmental uses. The granulated blast furnace slag has similar characteristics to glue, and low resistivity was found. With a cement-hydrate catalyst, it can be used to produce glue and, as such, it should be used as a grounding resistance reduction agent. Adding different proportions of water, cement, and salt, the resistivity and clot strength of the grounding resistance reduction agent was studied to find an optimal combination. This finished product can be used in a grounding resistance reduction agent, within which the grounding bar is buried. Our measurements have shown that this method can effectively reduce grounding resistance.
