Wood wastes from the eucalyptus products (plywood, veneer, MDP, cellulose, MDF, sawnwood) could be a source of raw material for the production of CBPB.
No study is available in Brazil on the application of CBPB for flooring.
The CBPB panels were sent to the Forest Products Laboratory (LPF) in Brasilia, Brazil, and finished by overlaying one face either with wood or with veneer for producing the flooring panels.
Four kinds of commercial glues, used for bonding solid and laminated wood flooring, were used in assembling the wood or veneer to the CBPB panels.
The density at 12 percent MC of the CBPB flooring panels overlaid with wood of tauari (density of 0.
The A503 and A602 glues did not resist the humidity test and, despite the good dimensional stability, the overlay was detached from the CBPB.
These results are well above the specifications of major CBPB producers, such as Bison type HZ cement-bonded boards (3,000 MPa) (NCL Group 2009), Versaroc (4,949 MPa) (Versaroc 2009), and Cetris (4,500 MPa) (Cetris 2009), all having application for floorings.
