| Abstract Scope |
Brazil has been standing out in the agroindustrial production in which large volumes of waste are generated. Natural fibers have been studied in different composites, especially cementitious. This research aimed to evaluate fibers from the pineapple crown for their application in coating mortars. The residue was submitted to wetting and drying cycles and, were treated in variable parameters: reagent concentration (5% and 10%), exposure time to chemical attack (30 min and 60 min), and type of reagent (NaOH and Ca (OH) 2 ). The fibers were incorporated with 1.5% in relation to the mass of cement of the produced mortar and compared with the reference mortar (0%), which were evaluated in the fresh state. It was found that the treatment with NaOH was the one that most degraded the external surface of the fiber and the produced mortars showed satisfactory performance, thus contributing to the development of alternative materials. |
