Density and Strength Properties of Lightweight Composite Panel using Polysilicon Sludge

Sangsoo Lee, Jeonggeun Lim


Environmental pollution problem related to global warming is rising all over the world, and the solar-light power generation in eco-friendly energy production industry uses polysilicon sludge as main material. Waste of 2 ton polysilicon sludge is generated in order to produce polysilicon 1 ton, which creates another environmental pollution to produce eco-friendly energy. Recently, the previous wet construction method has continuously changed to dried lightweight wall panels in construction works but the existing lightweight wall panel needs separate curing process with poor water resistance as well as fire resistance and so, it is required to have a research to replace it. In this connection, this study aims to analyze density and strength properties of lightweight composite panel utilizing polysilicon sludge. Lightweight composite panel was manufactured using only inorganic materials without using cement for both surface and core material of panel, and density of core material was 0.79g/cm3, compressive strength showed 6.23MPa, and flexural strength of panel was 10.8MPa.
