Lignocellulosic composites from Brazilian giant bamboo (Guadua magna): Part 2: Properties of cement and gypsum bonded particleboards

In the first part of this study, the feasibility of manufacturing resin-bonded particleboard from the recently identified Brazilian giant bamboo (Guadua magna) was evaluated. In this second part, the main goal was to study the material properties of the cement and gypsum-composites made from that ba...
