Foram avaliadas as propriedades físicas e mecânicas de painéis de E. urophylla, variando-se a relação madeira-casca com o cimento Portland. Os resultados apontaram que painéis produzidos com até 10% de casca, apresentam resultados equivalentes aos painéis produzidos com 100% de partículas de madeira, para as propriedades de LI e MOE. Esta percentagem chega a 25% para as demais propriedades. Os painéis produzidos com 100% de casca apresentaram a menor performance em todas as propriedades avaliadas.
It was evaluated the physical and mechanical properties of panels of E. urophylla with varying proportions of wood-bark with the Portland cement. The results showed that panels produced with up to 10% of bark presented equivalent results of panels produced with 100% of wood particles, for properties of internal bond and MOE. This percentage is as much as 25% for the other properties. The panels produced with 100% of bark presented the lower properties in all of the properties evaluated.
