Density and Strength Properties according to the Paper Ash addition ratio of the Lightweight Composite Panel Core Using the Blast Furnace Slag and Polysilicon Sludge

고로슬래그와 폴리실리콘 슬러지를 활용한 경량복합패널 심재의 제지애시 첨가율에 따른 밀도 및 강도특성

Recently, solar energy generation is one of the fastest growing industries for eco-friendly energy. Every year, solar energy generation industry grows to 42% on average. However, polysilicon sludge is generated from processing of polysilicon but, there is nothing to handle that. Therefore, we need research to recycle polysilicon sludge. Also, improved fire resistance efficiency of wall is required according to reinforced fire safety standards due to many cases of big fires in our country. This study focuses on density and strength properties according to the addition ratio of paper Ash for the lightweight composite panel core with polysilicon sludge. As a result of the test, adding paper ash 9% has the best density and strength properties.
