Production and study of polymeric composite based on recycled waste from civil construction

Abstract

As awareness of environmental issues grows, society recognizes the need for change, and more consumers advocate for environmentally friendly products. Consequently, the construction industry is compelled to devise new strategies to meet these demands. Construction and Demolition Waste (CDW) arises from construction, renovation, or demolition activities, constituting a residual product that has a significant negative impact on the environment. Expanded Polystyrene (EPS), also known as "Styrofoam," is a polymer-based material characterized by its low density, high flexibility, exceptional thermal, acoustic, and chemical resistance, in addition to being entirely recyclable. Composites refer to materials created by combining one or more materials with a matrix, also known as a reinforcement or filler load. This work aimed to conduct research by producing composite materials with a polymer matrix based on expanded polystyrene reinforced with CDW particles. The incorporation of CDW into expanded polystyrene was proposed through its dissolution in the solvent "acetone," enabling the mixing of CDW particles into the polymer matrix. Through structural characterization and mechanical properties, it is intended that the study of this new material can fill gaps in research on the reuse of construction and demolition waste in the field of civil engineering.
