摘要: Abstract Control and hot water treated particles of cypress ( Cupressus spp.) were used to manufacture cement-bonded particleboards (CBPB). Three replications carried out for each treatment, totaling six single layered boards. Physical mechanical properties the boards evaluated according ASTM D 1037-96a [Annual Book Standards, vols. 04–09. Philadelphia: American Society Testing Materials––ASTM, 1037-96a, 1998] standard. The wood showed suitability as raw material CBPB. All CBPB higher than Bison HZ type building reference. light color easy processing are favorable parameters panels manufacturing. results corroborate those reported using pine, rubberwood, acacia, babassu, eucalyptus particles. also submitted fungi decay resistance test 2017-81 1994-e1. 2017-81, p. 324–8] standard exposed attack Gloeophyllum trabeum (Persoon ex Fries) Murr. Trametes versicolor (Linnaeus Pilat. Twelve specimens tested treatment average weight loss was determined after 12 weeks exposure. Laboratory tests that there no measurable degradation (weight loss). Fungi mycelium did not even cover completely surface specimens. when both brown- white-rot fungi, rather loss, gains ranging from 2% 4%. Therefore, is technically suitable exterior use where moisture conditions development present.
