Strength Properties of Recycled Waste Plastic and Quarry Dust as Substitute to Coarse Aggregates: an Experimental Methodology

Plastic waste disposal is a significant environmental concern due to its low degradability and management practices, especially in developing countries. recycling considered the most effective method, which minimizes impacts. This paper discusses use of poly(ethylene terephthalate) (PET), high-density polyethylene (HDPE), polypropylene (PP) plastic as aggregates concrete industry by incorporating quarry dust base material. An experimental mix design series was carried out, followed deoxygenated heat treatment on each mixture for optimum bonding. Compressive strength, specific gravity water absorption properties were then investigated mixture. Although PET 30% lower than natural aggregates, higher HDPE or PP aggregates. Therefore, proposed method ideal low-strength components.
