Abstract
Concrete is a composite material made from cement, fine aggregates, coarse aggregates, and water. The issue of extensive exploitation has arisen due to continuous global development. Efforts have been made to reduce plastic waste through recycling. This aligns with research aimed at finding ways to make plastic waste more useful and replace certain materials, from furniture to construction materials. The goal of this research is to obtain the characteristics of processed plastic waste and compare various parameter values with coarse aggregates according to the requirements as concrete mix material (referring to the Indonesian National Standard). The methods employed include plastic waste sorting, washing, burning, and mixing with sand variations (2 variants) to add rigidity to the plastic, followed by pouring into molds. The plastic is then crushed to resemble coarse aggregates. The bulk density of plastic aggregates (PA) are 631.89 kg/m3 (PA1), 706.85 kg/m3 (PA 2) and 763.02 kg/m3 (PA3). The spesific gravity of plastic aggregates are 0.99 (PA1), 1.09 (PA2) and 1.15 (PA3). The absorbtion of aggregates are -0.69 (PA1), 0.59 (PA2) and 0.32 (PA3).
