Concrete with incorporation of polymeric recycled aggregate

Abstract

This study aims to evaluate the properties of a concrete with polymeric glue residue aggregate, through formulations by replacing natural coarse aggregate (NCA) with polymeric coarse aggregate (PCA). The gradual increase in the PCA content resulted in a reduction in consistency, specific gravity, compressive and flexural strength. However, there was an increase in the void ratio and water absorption. Regarding durability, the partial replacement of 40% of NCA by PCA showed the best performance. The conclusion is that it is possible to use polymer glue waste as aggregate in the production of concrete, helping to reduce the extraction of raw materials and the pollution of this waste in the environment. Its use in concrete production can increase the durability of this material, which will reduce building maintenance.
