Abstract

Plastic consumption is increasing on a daily basis, despite efforts to minimize it. On the other hand, the management of waste plastic was a significant issue in several countries around the world. A healthy and sustainable reuse of plastics has numerous benefits. The acceptability and benefits of recycled plastics as Coarse aggregate in concrete are explored here. Plastic aggregate parameters such as density and specific gravity were determined through tests. Because complete replacement of natural Coarse aggregate with plastic Coarse aggregate is impractical, partial replacement at various percentages was investigated. In addition to that silica fume is added as a binding material at a constant of 10%. The substitution of 15 Percent Plastic aggregate resulted in high compressive, splitting tensile, and flexural strength.
