  Plastic Wastes as a Raw Material in the Concrete Mix: An Alternative Approach to Manage Plastic Wastes in Developing Countries
  Author(s): Yalemsew Adela*, Mohamed Berhanu and Biruk Gobena
  
  The twenty-first century can be marked as a “plastic era” where different sectors are producing and consuming a huge amount of plastic. Concurrently, the plastic waste generation rate has been increasing and causing serious problems on the public health and ecosystem. Hence, recycling of plastic wastes can be one alternative management option for this peculiar waste stream. This study aims to evaluate the technical feasibility of plastic wastes as a partial replacement of coarse aggregate in a concrete mix using volcanic pumice as an admixture. Concrete test specimens prepared with standard M20 mix design were measured for a compressive and split tensile strength. Plastic aggregate made from plastic bags and bottles has shown a different degree of workability to replace the concrete mix. The compressive and split tensile strength tends to decrease with increasing the ratio.. View more»
