The waste was mechanically activated at dry conditions at room temperature for 30 minutes. Strength characteristics - impact, bending and compressive strength - dependance on the waste concentration was determined. The optimal results were achieved at waste concentration of 10 w.%. Morphology observations of filled systems were performed to clarify the influence of the structure on composite's properties.enArticle
