MANUFACTURING METHOD OF CONCRETE USING WASTE VINYL AGGREGATE

摘要

PURPOSE: A production method of concrete using waste plastic aggregate is provided to improve the intensity and thermal insulation of the concrete by molding the waste plastic aggregate into a polygonal shape, and to reduce the weight of a concrete structure. CONSTITUTION: A production method of concrete using waste plastic aggregate comprises the following steps: heating a waste plastic material at a high temperature for melting (S100); extruding the molten gel form waste plastic material into a polygonal shape for molding (S200); cooling the waste plastic aggregate (S300); and producing the concrete using the waste plastic aggregate (S400). In the heating step, the waste plastic material is heated at 150-250°C. In the heating step, the waste plastic material is mixed with more than one material selected from soil, waste plastic, waste tire powder, and sludge.
