Abstract

Recently, with development of the industry the globally Global warming is accelerating. Further, to the due depletion of natural resources, have been made many efforts to produce green energy. In particular, solar power generation industry has grown rapidly at an annual average rate of over 42%, the fastest rate. But, is generated sludge about 2tons in order to produce 1ton in the solar power generation used main material polysilicon. In this way, the arising sludge there is not method recycling and it is all discarded. Therefore, in the present study by the research on the properties of inorganic binder using the blast furnace slag and sludge seeks the polysilicon of the polysilicon sludge recycling methods. The experiment of the Series I was conducted in order to analyze the appropriate addition rate of the alkali activator. And the experiment of Series II was conducted in order to analyze the appropriate replacement ratio of the polysilicon sludge. The appropriate addition rate of the NaOH, that is the alkali activator, was exposed to be 7%. And the appropriate replacement ratio of the polysilicon sludge was exposed to be 8%.
