Resumo: | http://dx.doi.org/10.5902/1980509813339This research was developed with the objective of evaluating the potential use of residues of the productionof Pinus spp. sawnwood, as substitution to the fine aggregate of the concrete used for the production ofblocks for structural masonry. The evaluation of the physical characteristics (density, porosity and waterabsorption) and mechanics (compression and tension strength) of the concrete was evaluated in agreementwith the ABNT normalization. Substitutions of the fine aggregate were tested by percentages of 0, 20,40, 60, 80 and 100% of residue of Pinus spp. in natura, Pinus spp. in natura and with addition of 4,5%CaCl2.2H2O and residue of Pinus spp. pre-treated with extraction in cold water for 48 hours (AF-48H).The compositions were initially used for the production, in laboratory, of cylindrical specimens of 50 mmdiameter, by the use of a molding system for vibrate-compression and later, for producing blocks, withoptimized compositions, in vibrate-press commercial machine. Satisfactory results were obtained withsubstitutions of up to 50% of the mineral fine aggregate for the residue of Pinus spp. |

A avaliação das características físicas (massa específica, índice de vazios e absorção de água) e mecânicas (resistência à compressão e à tração) do concreto foi realizada conforme normas da ABNT. Foram testadas substituições do agregado miúdo por teores de 0, 20, 40, 60, 80 e 100% de resíduo de Pinus spp. in natura, Pinus spp. in natura e com adição de 4,5% de CaCl2.2H2O e resíduo de Pinus spp. pré-tratado com extração em água fria por 48 horas (AF48H). As composições foram inicialmente utilizadas para a produção em laboratório, de corpos de prova cilíndricos de 50 mm, com o uso de um sistema de moldagem por vibrocompressão e posteriormente, para produção de blocos, com os traços otimizados, em máquina vibroprensa. Obtiveram-se resultados satisfatórios com substituições de até 50% do agregado miúdo mineral pelo resíduo de Pinus spp.Universidade Federal de Santa Maria2014-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1333910.5902/1980509813339Ciência Florestal; Vol. 24 No. 1 (2014); 223-235Ciência Florestal; v. 24 n. 1 (2014); 223-2351980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/13339/pdfLima, Adauto José Miranda deIwakiri, Setsuoinfo:eu-repo/semantics/openAccess2017-04-13T18:25:02Zoai:ojs.pkp.sfu.ca:article/13339Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-13T18:25:02Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
