|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.
