AB  - Incorporating recycled plastic waste in concrete manufacturing is one of the most 
      ecologically and economically sustainable solutions for the rapid trends of 
      annual plastic disposal and natural resource depletion worldwide. This paper 
      comprehensively reviews the literature on engineering performance of recycled 
      high-density polyethylene (HDPE) incorporated in concrete in the forms of 
      aggregates or fiber or cementitious material. Optimum 28-days' compressive and 
      flexural strength of HDPE fine aggregate concrete is observed at HDPE-10 and 
      splitting tensile strength at HDPE-5 whereas for HDPE coarse aggregate concrete, 
      within the range of 10% to 15% of HDPE incorporation and at HDPE-15, 
      respectively. Similarly, 28-days' flexural and splitting tensile strength of HDPE 
      fiber reinforced concrete is increased to an optimum of 4.9 MPa at HDPE-3 and 4.4 
      MPa at HDPE-3.5, respectively, and higher than the standard/plain concrete matrix 
      (HDPE-0) in all HDPE inclusion levels. Hydrophobicity, smooth surface texture and 
      non-reactivity of HDPE has resulted in weaker bonds between concrete matrix and 
      HDPE and thereby reducing both mechanical and durability performances of HDPE 
      concrete with the increase of HDPE. Overall, this is the first ever review to 
      present and analyze the current state of the mechanical and durability 
      performance of recycled HDPE as a sustainable construction material, hence, 
      advancing the research into better performance and successful applications of 
      HDPE concrete.
