Resumo: The aim of this work was to evaluate the potential use of three different chemical additives (CaCl2, MgCl2 and hydrated lime) in the production of wood-cement composites made with particles from the slab wood of piãozinho (Eschweilera coriaceae (DC.) Mart), matá-mata branco (Eschweilera odora (poepp.) Miers) and Portland cement CP II-Z, with a wood:cement ratio of 1:2,75, by the vibro-compaction densification method. The compatibility test between wood and cement indicated that both species were suitable for the composites production when pre-treated and mixed with chemical additives. Main results: (I) The two species of the Eschweilera genus are suitable for wood-cement composite productions; Composites produced with piãozinho (Eschweilera coriaceae) particles presented better results (II) The use of CaCl2 had a positive effect on the mechanical properties of composites with Eschweilera coriaceae wood; and (III) The use of hydrated lime as chemical additives is not recommended when the method of densification by vibro-compaction is applied.

Mart) e matá-mata-branco (Eschweilera odora (poepp.) Miers) e cimento Portland tipo CP II-Z, na razão 1:2,75, pelo método de adensamento por vibrocompactação. Teste de compatibilidade entre a madeira e cimento mostrou que essas espécies são aptas para a produção de compósitos quando pré-tratadas com o uso de aditivos químicos na mistura. Com base nos resultados, pode-se concluir que: (I) As espécies do gênero Eschweilera estudadas são aptas para produção de compósitos madeira-cimento, sendo que compósitos produzidos com a madeira de piãozinho (Eschweilera coriaceae) obtiveram melhores resultados; (II) A adição de CaCl2 teve efeito positivo nas propriedades mecânicas dos compósitos de Eschweilera coriaceae; e (III) Não é recomendável o uso de cal hidratada como aditivo químico quando o método utilizado é o de vibrocompactação.Universidade Federal de Santa Maria2019-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1949710.5902/1980509819497Ciência Florestal; Vol. 29 No. 3 (2019); 1343-1353Ciência Florestal; v. 29 n. 3 (2019); 1343-13531980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/19497/pdfCopyright (c) 2019 Ciência Florestalinfo:eu-repo/semantics/openAccessCastro, Vinicius Gomes deAzambuja, Rafael da RosaParchen, Carlos Frederico AliceIwakiri, Setsuo2019-10-01T13:06:32Zoai:ojs.pkp.sfu.ca:article/19497Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2019-10-01T13:06:32Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
