Abstract

This research was developed to evaluate the potential use of Schizolobium amazonicum “Paricá” and Cecropia hololeuca “Embaúba” wood for wood cement board manufacture. Panels with the density of 1.200 kg/m³ were made, using cement CP V ARI as mineral bonding and wood particles without treatment and treated with immersion in cold water, hot water and sodium hydroxide. The panels were pressed at the pressure of 40 kgf/cm², room temperature and press / clipping time of 24 hours and maturation time of 28 days. The evaluation of the properties of water absorption, thickness swelling, internal bond, modulus of elasticity and modulus of rupture, showed that Schizolobium amazonicum “Paricá” and Cecropia hololeuca “Embaúba” wood are technically feasible for wood-cement board manufacture. It was also found that the panels of embaúba exhibit some properties superior to those of the paricá, and the particles do not necessarily need treatment.
