Impact strength and behavior of concrete containing different plastic wastes

Abstract

The growth of post consumed plastic wastes requires recycling to save the environment against pollution. One solution is the reuse of the waste as a substantially material for concrete production. Different properties of concrete containing different plastic wastes have been investigated by the past researchers. In this study, impact strength and behavior of normal strength concrete contained shredded PVC waste aggregate or PET waste fiber has been investigated experimentally. Results show that there is a first crack impact and ultimate impact loads enhancement of 97% and 23% as a result of using 20 mm length PET fiber added to concrete by 0.75%. The impact performance of 40 mm length PET fiber was found to be lower as compared with that of 20 mm length fiber to enhance impact. There is a reduction in both first crack impact and ultimate load impact of concrete as a result of replacing a part of fine aggregate with a PVC waste aggregate reaching 84% related to using 45% PVC aggregate as fine aggregate replacement. Results also show that there is a strong linear relationship between the first crack impact and ultimate load impact for concrete contained PET fiber or PVC aggregate.
