Influence of wood treatments on mechanical properties of wood-cement composites and of Populus Euroamericana wood fibers
Woodecement composites are interesting materials for structural and isolation purposes. Dimensional stability, economic factors and resistance to environmental degradation are features that can be exploited for housing ...
THE EFFECT OF HEAT TREATMENT ON SOME PROPERTIES AND COLOUR IN EUCALYPTUS (Eucalyptus camaldulensis DEHN.) WOOD
(Universidad del Bío-Bío, 2003)
Static bending strength of heat-treated and chromated copper arsenate-treated plywood
Plywood can be used in the furniture industry and in civil construction due to its structural strength. However, for long useful life in construction, especially in tropical countries, it needs to undergo treatments against ...
Influence of Indian cedar particle pretreatments on cement-wood composite properties
This work physically, mechanically, and chemically characterized the composites produced from Portland CP II-E32 cement and fresh Indian cedar wood particles previously treated by immersion in hot and cold water. Density ...
Combining steam explosion with 1-ethyl-3-methylimidazlium acetate treatment of wood yields lignin-coated cellulose nanocrystals of high aspect ratio
Lignin-coated cellulose nanocrystals (CNCs) were extracted from the tropical wood Angelim Vermelho in a yield of 47 % based on wood cellulose content. The procedure combined a mild steam explosion process with a treatment ...
Physical properties of thermally modified juvenile and mature wood of Hevea brasiliensis (Euphorbiaceae)
Exposing timber to temperatures approaching 200 °C causes thermal modification and changes its characteristics. This study evaluates the effect of various levels of thermal treatment on the physical properties of juvenile ...
Physical and chemical changes in juvenile and mature woods of Pinus elliottii var. elliottii by thermal modification
This study is aimed at evaluating the effect of thermal treatment on the physical and chemical properties of juvenile and mature wood from Pinus elliottii. Boards were taken from 35-year-old P. elliottii var. elliottii ...
Treatments of residual pine strands: characterization and wood-cement-compatibility
This paper aims to evaluate treatments on pine strands as well as wood-cement compatibility. The strands were prepared and then were submitted to four treatments (untreated; cold water, hot water and NaOH). Physical, ...
