Physical and mechanical characterization of gypsum matrix bio-composite

Session

Description

The present research aims to assess the physical and mechanical characteristics of gypsum-based bio-composites reinforced with Eucalyptus urophylla wood particles. Bio-composites with volume additions of 0%, 25%, and 50% were produced and evaluated. The results of the mechanical tests showed a statistically significant difference among the treatments, with the bio-composite with a 25% particle addition achieving a flexural strength of 2.81 Mpa and a compressive strength of 3.62 Mpa. There was a significant decrease in apparent density as the particle addition increased, with the composite with a 50% particle addition having a density of 0.71 g/cm³. All the results met normative requirements, with lower density compared to the control, demonstrating the feasibility of using the bio-composite as it fulfills the mechanical needs with less density.
