Abstract

Concrete is one of the most commonly used materials for construction. Due to the increased of concrete demand, the need for alternative material to substitute natural aggregate becomes crucial. In this study HDPE plastic waste was used as artificial aggregate. HDPE was mixed with natural coarse aggregate at variation of 0%, 10%, 15% and 20%. Compressive test and split tensile tests were performed on concrete age of 28 days. The compressive strength of concrete decreased with the addition of HDPE levels. The result shows that the highest value of compressive strength was 27,88 MPa on 0% HDPE and the lowest value was 11,08 MPa on 20% HDPE mixture. The highest split tensile strength achieved by normal concrete of 2,71 MPa. Split tensile strength of concrete gradually decreased with the addition of HDPE variations. The lowest value of tensile strength was obtained from variation of 20% HDPE plastic waste that is equal to 1.72 MPa. From the analysis it can be concluded that the replacement of coarse aggregate crushed stone with HDPE plastic waste reduce split tensile strength of concrete.
