| Popis: | In this work, was performed a comparative analysis of the mechanical properties resulting from the addition of sisal and piassava fibers in lightweight cementitious composites with EVA. The workability, compressive strength, apparent specific mass, tensile strength in bending and deformation capacity were assessed in mixtures and cylindrical and prismatic specimens. EVA reduced apparent specific mass and mechanical properties of the composites. Sisal produced a maximum increase of 49.08% in tensile strength in bending of cementitious matrix with EVA, whereas piassava ensured greater deformation capacity up to rupture, with maximum elongation of 12.693 mm. Ultimately, sisal was more efficient as reinforcement. |
