Abstract:
High performance coatings (HPC) are floors that protect substrates in several types of Brazilian industries. Its use is necessary due to several benefits such as speed of application, high mechanical performance and absence of expansion joints. However, the Brazilian standard mentions manufacturing with epoxy resins, of synthetic origin, and mineral aggregates. Therefore, this work aimed to study the mechanical performance of this material using a vegetable polyurethane resin and, as an aggregate, piassava fiber ground in the knife mill. The fiber used was obtained as an industrial by-product of a broom factory located in Campos dos Goytacazes-RJ. The research methodology consisted, initially, in the determination of the density of the fibers collected as waste through the pycnometry technique, as well as the morphological analysis through scanning electron microscopy (SEM). Subsequently, water absorption tests were carried out after boiling, compressive strength and fracture analysis using SEM. The results showed the efficiency of using 20% fiber that makes it possible to apply this composition for formulation and use in RAD.
