Resumo: | Through the environmental perspective of producing new construction materials with the inclusion of tailings or residues that improve their properties and, at the same time, promote a practice that mitigates environmental impacts, the objective of this work is to diagnose the effect of incorporating scheelite- tailings as recycled aggregate in soil-cement bricks, partially replacing the soil, seeking to make its use feasible in interlocking pavements, as well as studying the physical-chemical properties of the mixing water used in the making of soil-cement bricks, originating from drains air conditioning system at IFPB Campus Campina Grande. The bricks produced used CP II Z-32 class cement, landfill cut-off soil for disposal, scheelite-tailings, and kneading water from air conditioning drains at the IFPB Campus Campina Grande. Conformation was performed manually with the aid of a hydraulic press, with subsequent curing at room temperature and periodic wetting during the first 7 days of cement hydration (alkaline stabilizer), until the ages of laboratory tests of compressive strength reached (28 days) and direct flexion (180 days). It was noted that the results of compressive strength exceeded the minimum limits of ABNT NBR 10834:2013, as well as the results of the flexion test demonstrated that the mechanical strength of the bricks is superior when incorporating the mineral tailings, a phenomenon also noticed through of the compressive strength test. The quality of the water used to manufacture the bricks, in addition to ensuring better chemical potential in the hydration reaction based on the state of the art, promotes a reduction in the use of water from the public supply, which comes from a relatively low water source. |

Los ladrillos producidos utilizaron cemento clase CP II Z-32, tierra de corte de relleno sanitario para eliminación, desechos minerales de scheelita y agua de amasado de los desagües de aire acondicionado en el IFPB Campus Campina Grande. La conformación se realizó manualmente con ayuda de una prensa hidráulica, con posterior curado a temperatura ambiente y humedecimiento periódico durante los primeros 7 días de hidratación del cemento (estabilizador alcalino), hasta alcanzar las edades de los ensayos de laboratorio de resistencia a la compresión axial (28 días) y flexión directa (180 días). Se notó que los resultados de resistencia a la compresión axial excedieron los límites mínimos de ABNT NBR 10834:2013, así como los resultados del ensayo de flexión demostraron que la resistencia mecánica de los ladrillos es superior al incorporar el residuo mineral, fenómeno también notado a través de la prueba de compresión axial. La calidad del agua utilizada para fabricar los ladrillos, además de asegurar un mejor potencial químico en la reacción de hidratación basada en el estado de la técnica, promueve una reducción en el uso de agua del suministro público, que proviene de un agua relativamente baja fuente.Através da perspectiva ambiental em produzir novos materiais de construção com inclusão de rejeitos ou resíduos que melhorem suas propriedades e, ao mesmo tempo, promovam uma prática mitigadora dos impactos ambientais, objetiva-se com esse trabalho diagnosticar o efeito da incorporação do rejeito da extração da scheelita como agregado reciclado em tijolos maciços de solo-cimento substituindo parcialmente o solo, buscando viabilizar seu uso em pavimentos intertravados, bem como, estudar as propriedades físico-químicas da água de amassamento utilizada na confecção dos tijolos de solo-cimento, oriunda dos drenos de ar condicionado do IFPB Campus Campina Grande. Os tijolos produzidos utilizaram cimento de classe CP II Z-32, solo de recorte de aterro para descarte, rejeito mineral da scheelita, e água de amassamento proveniente de drenos de ar condicionado do IFPB Campus Campina Grande. A conformação foi realizada manualmente com o auxílio de prensa hidráulica, com posterior cura à temperatura ambiente e molhagem periódica durante os 7 primeiros dias de hidratação do cimento (estabilizador alcalino), até atingirem as idades de realização dos testes laboratoriais de resistência à compressão axial (28 dias) e flexão direta (180 dias). Notou-se que os resultados de resistência à compressão axial superaram os limites mínimos da ABNT NBR 10834:2013, como também, os resultados do teste de flexão demonstraram que a resistência mecânica dos tijolos é superior quando incorporado o rejeito mineral, fenômeno também notado através do teste de compressão axial. A qualidade da água utilizada para fabricar os tijolos, além de assegurar melhor potencial químico na reação de hidratação com base no estado da arte, promove a redução do uso da água do abastecimento público, que advém de manancial com aporte hídrico relativamente reduzido.Research, Society and Development2021-05-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1541210.33448/rsd-v10i6.15412Research, Society and Development; Vol. 10 No. 6; e0210615412Research, Society and Development; Vol. 10 Núm. 6; e0210615412Research, Society and Development; v. 10 n. 6; e02106154122525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/15412/13766Copyright (c) 2021 João Victor da Cunha Oliveira; Frankslale Fabian Diniz de Andrade Meira; Leila Soares Viegas Barreto Chagashttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessOliveira, João Victor da CunhaMeira, Frankslale Fabian Diniz de Andrade Chagas, Leila Soares Viegas Barreto2021-06-10T22:51:46Zoai:ojs.pkp.sfu.ca:article/15412Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:36:14.432122Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
