Incorporation of EVA Residue for Production of Lightweight Concrete
The use of residues as lightweight aggregates in concrete enables the production of so-called lightweight concrete. These compounds present many particular characteristics, such as the low specific mass when replacing the gravel by a lighter aggregate, directly influencing the weight of the structure, promoting the reduction of cross sections and consequent changes with the costs. In order to analyze the influence of these residues on the physical and mechanical properties of the concrete, a study was carried out with concretes composed of four different levels of incorporation. The incorporation of EVA residue was made by compensating the volume of the natural aggregate by the volume of EVA. The results indicated that the incorporation of 10% of EVA is feasible and allows the reduction of the environmental impact generated by the disposal of this residue.
