Resumo: Reinforced concrete consists of a material susceptible to attack by pathological manifestations caused by the flow of aggressive agents in its porous environment, which damage its steel armor, reduce the level of resistivity of its mechanical properties and generate irreversible damage to the structure when none intervention is carried out opportunely. Thanks to this, predictive mathematical models must be used as a preventive measure in order to contribute to the reduction of socioeconomic impacts caused by the interdiction of these structures to carry out corrective maintenance and to the reduction of the environmental impacts that are caused when a large-sized structure collapses. Thus, this research will present the most current predictive mathematical models in the international literature, through bibliographic review, which can be used to prevent damage caused by carbonation and by attack by chloride ions. Among the results found, the possibility of using mathematical models in the prediction of the aforementioned pathological manifestations is highlighted with the use of partial differential equations whose solutions can be obtained with the aid of computational software, beyond your contribution to the prevention of damage evolution promoted by the pathologies in question so that they do not reach a level where maintenance costs are higher, making it possible to carry out preventive maintenance at appropriate times in order to prolong the useful life of the structure.

Gracias a ello, se deben utilizar modelos matemáticos predictivos como medida preventiva con el fin de contribuir a la reducción de los impactos socioeconómicos provocados por la interdicción de estas estructuras para realizar mantenimientos correctivos y a la reducción de los impactos ambientales que se provocan cuando una gran estructura se derrumba. Así, esta investigación presentará los modelos matemáticos predictivos más actuales en la literatura internacional, mediante revisión bibliográfica, los cuales pueden ser utilizados para prevenir daños por carbonatación y por ataque de iones cloruro. Entre los resultados encontrados, se destaca la posibilidad de utilizar modelos matemáticos en la predicción de las manifestaciones patológicas antes mencionadas con el uso de ecuaciones diferenciales parciales cuyas soluciones se pueden obtener con la ayuda de software computacional, además de su contribución a la prevención de evolución de daños promovida por las patologías en cuestión para que no alcancen un nivel en el que los costes de mantenimiento sean mayores, permitiendo realizar mantenimientos preventivos en los momentos oportunos con el fin de prolongar la vida útil de la estructura.O concreto armado consiste em um material suscetível ao ataque de manifestações patológicas causadas pelo fluxo de agentes agressivos em seu meio poroso, os quais danificam a sua armadura de aço, reduzem o nível de resistividade de suas propriedades mecânicas e geram danos irreversíveis na estrutura quando nenhuma intervenção é realizada oportunamente. Graças a isso, modelos matemáticos preditivos devem ser utilizados como medida preventiva de forma a contribuir com a redução dos impactos socioeconômicos causados pela interdição dessas estruturas para realização de manutenções corretivas e com a redução dos impactos ambientais que são causados quando ocorre o colapso de uma estrutura de grande porte. Dessa forma, a presente pesquisa apresentará os modelos matemáticos preditivos mais atuais existentes na literatura internacional, através de revisão bibliográfica, os quais podem ser utilizados para prevenção dos danos causados pela carbonatação e pelo ataque de íons cloreto. Dentre os resultados encontrados destacam-se a possibilidade de utilização de modelos matemáticos na predição das manifestações patológicas supracitadas com a utilização de equações diferenciais parciais cujas soluções podem ser obtidas com o auxílio de softwares computacionais, além da sua contribuição com a prevenção da evolução dos danos promovidos pelas patologias em questão de maneira que eles não atinjam um patamar onde os custos com manutenções sejam mais elevados, viabilizando a realização de manutenções preventivas em períodos adequados com o objetivo de se prolongar a vida útil da estrutura.Research, Society and Development2021-05-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1496110.33448/rsd-v10i6.14961Research, Society and Development; Vol. 10 No. 6; e21710614961Research, Society and Development; Vol. 10 Núm. 6; e21710614961Research, Society and Development; v. 10 n. 6; e217106149612525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/14961/14036Copyright (c) 2021 Silvandro Ferreira de Siqueira Júnior; Arnaldo Manoel Pereira Carneirohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSiqueira Júnior, Silvandro Ferreira de Carneiro, Arnaldo Manoel Pereira 2021-06-10T22:51:46Zoai:ojs.pkp.sfu.ca:article/14961Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:35:54.437132Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
