ABSTRACT: This study is part of a sustainable innovation initiative, proposing the use of plastic waste as a binder, combined with flint, for the formulation of environmentally friendly polymer concrete. The aim is to demonstrate the technical feasibility of replacing traditional cementitious binders while ensuring reliable adhesion between metal reinforcements and the polymer matrix. A comparative study was conducted between conventional cement concrete and several formulations based on melted plastics. The results showed that PET + flint concrete offers remarkable adhesion (8.06 MPa), superior to cement concrete (6.59 MPa), for which the values set by the BAEL 91 and Eurocode 2 standard are between 2.8 and 3.2 MPa. Although HDPE and PP-based concretes have slightly lower adhesion, they exceed the usual reference values while displaying improved compressive strength, in line with previous studies. These results confirm the feasibility of polymer concretes reinforced with reinforcement for specific uses such as the prefabrication of components for use in roads, networks and various other applications, as well as in wet areas.
