Resumo: | Concrete has advantages such as economy, malleability, durability, resistance, and may have low permeability and maintenance cost. However, the occurrence of cracks is not uncommon, which can occur due to hygrothermal, hygroscopic and other variations. Such cracks are aggravated by the action of weathering agents. In this sense, the present work sought to verify whether the use of ureolytic bacteria, of the type Bacillus subitilis, could correct the cracks through the process of biomineralization and by converting nutrients such as calcium lactate into limestone through the precipitation of calcium carbonate. The sample of Bacillus subitilis was discovered in leachate in a landfill, located in the community of Perema, municipality of Santarém-Pará, Brazil. After the characterization of the sample, temperature resistance test and preparation of the bacteriological solution, the content was applied to fissures of three specimens with fissures of 0.1 mm, 1 mm and 2 mm. After a period of six days, the cracks in the three PCs were completely regenerated, showing the high capacity of Bacillus subitilis in the calcification of the cracks. The results, therefore, proved to be promising, directing the development of new technologies in this field, as well as awakening another look at the environmental issue linked to leachate. |

Sin embargo, no es infrecuente la aparición de grietas, que pueden ocurrir debido a variaciones higrotérmicas, higroscópicas y de otro tipo. Estas grietas se ven agravadas por la acción de agentes meteorológicos. En este sentido, el presente trabajo buscó verificar si el uso de bacterias ureolíticas, del tipo Bacillus subitilis, podría corregir las grietas mediante el proceso de biomineralización y mediante la conversión de nutrientes como el lactato cálcico en caliza mediante la precipitación de carbonato cálcico. La muestra de Bacillus subitilis fue descubierta en lixiviados en un relleno sanitario, ubicado en la comunidad de Perema, municipio de Santarém-Pará, Brasil. Tras la caracterización de la muestra, ensayo de resistencia a la temperatura y preparación de la solución bacteriológica, se aplicó el contenido a fisuras de tres probetas con fisuras de 0,1 mm, 1 mm y 2 mm. Después de un período de seis días, las grietas en los tres PC se regeneraron por completo, mostrando la alta capacidad del Bacillus subitilis en la calcificación de las grietas. Los resultados, por tanto, demostraron ser prometedores, orientando el desarrollo de nuevas tecnologías en este campo, además de despertar una nueva mirada a la problemática medioambiental ligada a los lixiviados.O concreto apresenta vantagens como a economia, maleabilidade, durabilidade, resistência, podendo apresentar baixa permeabilidade e custo de manutenção. No entanto, não é incomum, a ocorrência de fissuras, que podem ocorrer por causa de variações higrotérmicas, higroscópicas e outras. Tais fissuras são agravadas pela ação dos agentes de intemperismo. Neste sentido, o presente trabalho buscou verificar se o uso de bactérias ureolíticas, do tipo Bacillus subitilis, poderia corrigir as fissuras por meio do processo de biomineralização e pela conversão de nutrientes como lactato de cálcio em calcário por meio da precipitação do carbonato de cálcio. A amostra de Bacillus subitilis foi descoberta em chorume em um aterro sanitário, localizado na comunidade de Perema, município de Santarém-Pará, Brasil. Após a caracterização da amostra, teste de resistência a temperatura e preparação da solução bacteriológica, o conteúdo foi aplicado em fissuras de três corpos de prova com fissuras de 0,1 mm, 1 mm e 2 mm. Após um período de seis dias as fissuras nos três CPs foram completamente regeneradas, mostrando a alta capacidade da Bacillus subitilis na calcificação das fissuras. Os resultados, portanto, mostraram-se promissores, direcionando o desenvolvimento de novas tecnologias neste campo, bem como despertando um outro olhar para a questão ambiental atrelada ao chorume.Research, Society and Development2021-05-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1573410.33448/rsd-v10i6.15734Research, Society and Development; Vol. 10 No. 6; e31510615734Research, Society and Development; Vol. 10 Núm. 6; e31510615734Research, Society and Development; v. 10 n. 6; e315106157342525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/15734/14124Copyright (c) 2021 Marilú Carvalho da Silva Gato; Wellington Muniz; Karina Barbosa da Silva; Márlison Santos de Sáhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessGato, Marilú Carvalho da Silva Muniz, WellingtonSilva, Karina Barbosa da Sá, Márlison Santos de2021-06-10T22:51:46Zoai:ojs.pkp.sfu.ca:article/15734Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:36:30.558904Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
