Recently, environmental pollution related to global warming is on the rise. Meanwhile, renewable energy is a representative example of many efforts to develop eco-friendly energy to solve the depletion of natural resources and the depletion of petroleum resources in conjunction with global warming. Among them, photovoltaic power generation is increasing the subsidies for the government to increase the production of photovoltaic electricity of the general public, showing a high growth rate. However, polysilicon, which is a raw material of the photovoltaic panel, generates waste called polysilicon sludge in the manufacturing process. In order to produce 1 ton of polysilicon, about 2 tons of waste polysilicon sludge is generated. In 2012, polysilicon sludge was generated at 78,000 tons, with an average of about 220 tons per day. The sludge generated due to insufficient treatment of polysilicon sludge is currently solidified and is processed by landfilling. Therefore, in this study, polysilicone sludge is used as the concept of admixture, and the physical properties of the matrix according to the polysilicon sludge replacement ratio based on light burned magnesia is determined.

In recent years, active loess cement has been used instead of cement in order to reduce the amount of cement and industrial byproducts that are the main cause of environmental pollution. We also used polysilicon sludge as a by-product to reduce the amount of cement used and to improve the environmental pollution due to the reduction of carbon dioxide. Polysilicon is a raw material used in the production of panels for solar power generation. When producing 1 ton of polysilicon, 2 tons of sludge is generated. It is an experiment to reduce sludge treatment and cement usage. This study analyzed basic characteristics of polysilicon sludge and active loess cement according to replacment ratio.

Researches for the development of renewable energy as a fuel substitute for global warming and depletion of petroleum resources are actively being carried out. Among them, the annual growth rate of PV generation is 20.73%, which is higher than other renewable energy sources. However, the production of 1 ton of polysilicon, which is known as a raw material for solar power generation panels, generates 2 tons of waste. As the demand for PV panels increases, the problem of the treatment of polysilicon sludge is attracting attention, and studies on the utilization of polysilicon sludge are needed. Therefore, in this study, the applicability of polysilicon sludge treated as industrial waste to the lightweight panel for architectural purposes was examined.

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.

The environmental pollution problem the globally related to global warming arises, the demand for the solar power generation increases. 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 this research, cement is not used dynamic properties tries to be analyze inorganic binder based on blast furnace slag and polysilicon sludge ratio. The appropriate replacement ratio of the experimental result polysilicon sludge was to be 8%.

This application plan is hasty prepared with the actual condition in which the majority is reclaimed by the waste with the marine and the polysilicon sludge, that is the main raw material of the solar pannel support, does. In this research, by using OPC and Fly ash, the applicability as the blending material of the polysilicon sludge was analyze and it tried to contribute to the waste reduction afterward. The replacement ratio of the sludge was set to 5. 10, 15, 20(%) with the experiment based on the based test result and the air flow rate, liquidity, flexural strength, and compressive strength was measured. The liquidity was reduced in spite of as the replacement ratio of the sludge increased and the air flow rate increased.

The environmental pollution problem the globally related to global warming arises. In the construction industry the cement mostly use material, generates the great quantity of CO₂ among the fired process and the global warming is more aggravated. In addition, the polysilicon that is the main raw material used in the solar power generation, produces 1 ton and the industrial by-product of 2 tons is generated. In this way, the arising sludge there is not method recycling and it is all discarded. Therefore, in this research, try to present as the fundamental research material for using the polysilicon sludge as the admixture of the cement in order to reduce the amount of the cement. The based on 'KS L ISO 679' was progressed mortar test. the liquidity, air flow rate, setting time, water absorption ratio, flexural and compression strength was measured. According to, appropriate replacement ratio of the polysilicon sludge tries to analyze.
