Resumo: | Ferruginous features occur frequently in soils of the Araguaia river plain, where profiles can be verified completely dominated by these characteristics. The objective of this study was to evaluate the physical variations in the plinthite and petroplinthite, considering: a) the compressive strength and stability of plinthic materials present in soils of the Araguaia river plain under natural drying and in a forced ventilation oven for different periods; b) the influence of different solutions and periods of immersion in the reversibility of hardening of plinthite and petroplinthite of the Araguaia river plain soils, both with the purpose of subsidizing the classification of these features. The study was carried out in five soil profiles in the Araguaia river flood plain, in Luiz Alves, district in the municipality of São Miguel do Araguaia, Goiás. A soil profile was also studied in Terezópolis de Goiás, Goiás, in the João Leite riverside flood plain. Soils samples were collected with PVC cylinders, directly in the plinthic horizons. From these samples were extract subsamples of plinthite and matrix of the soil. Homogenous samples of petroplinthite were also collected and separated into subsamples. Two experiments were carried out: in the first, plinthite, matrix of the soil and petroplinthite subsamples were submitted to two types of drying: in the natural environment and in a forced ventilation oven, and in the second, plinthite and petroplinthite subsamples were submitted to five hydration treatments: natural water, calcium carbonate solution, sodium hydroxide solution, sodium hydroxide + sodium hexametaphosphate solution and acid solution. The periods determined for the evaluations were 10, 20, 40, 80 and 160 days. The degrees of dispersion and stability and the compressive strength were evaluated. For the plinthite and petroplinthite of the same profile, there is a great variability of behavior as to the applied compression strength, which is associated with the iron contents that compose them. The immersion of plinthite and petroplinthite in solutions composed of chemical agents affects the dispersion, and the plinthite is more susceptible to the alkaline agents, with reduction of the compressive strength exercised. |

Este estudo objetivou avaliar as variações físicas na plintita e na petroplintita, considerando: a) a força de compressão e estabilidade de materiais plínticos presentes em solos da planície do rio Araguaia sob secagem natural e em estufa de ventilação forçada por períodos distintos; b) a influência de diferentes soluções e períodos de imersão na reversibilidade do endurecimento de plintita e petroplintita de solos da planície do rio Araguaia, ambos com finalidade de subsidiar a classificação dessas feições. O estudo foi realizado em cinco perfis de solos na planície de inundação do rio Araguaia, em Luiz Alves, distrito no município de São Miguel do Araguaia, Goiás. Para comparação entre os materiais plínticos, foi também estudado um perfil de solo no município de Terezópolis de Goiás, Goiás, na planície de inundação do ribeirão João Leite. Amostras de solos foram coletadas com auxílio de cilindros de PVC, diretamente nos horizontes plínticos. Dessas amostras foram separadas subamostras de plintita e matriz do solo. Foram também coletadas amostras homogêneas de petroplintita, igualmente separadas em subamostras. Foram desenvolvidos dois experimentos: no primeiro, subamostras de plintita, matriz do solo e petroplintita foram submetidas a dois tipos de secagem: em ambiente natural e em estufa de ventilação forçada e no segundo, subamostras de plintita e petroplintita foram submetidas a cinco tratamentos de hidratação: água natural, solução de carbonato de cálcio, solução de hidróxido de sódio, solução de hidróxido de sódio + hexametafosfato de sódio e solução ácida. Os períodos determinados para as avaliações foram 10, 20, 40, 80 e 160 dias. Foram avaliados os graus de dispersão e estabilidade e a resistência à compressão. Para a plintita e petroplintita de um mesmo perfil, existe grande variabilidade de comportamento quanto à força de compressão aplicada, a qual é associada aos teores de ferro que as compõem. A imersão da plintita e petroplintita em soluções compostas por agentes químicos afeta a dispersão, sendo que a plintita é mais susceptível aos agentes alcalinos, com redução de força de compressão exercida.Submitted by Marlene Santos (marlene.bc.ufg@gmail.com) on 2018-07-13T16:00:55Z No. of bitstreams: 2 Dissertação - Angélica Pires Batista Martins - 2017.pdf: 3335884 bytes, checksum: 89378cfa32c3cf46f97258266490ea63 (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Approved for entry into archive by Luciana Ferreira (lucgeral@gmail.com) on 2018-07-17T13:34:10Z (GMT) No. of bitstreams: 2 Dissertação - Angélica Pires Batista Martins - 2017.pdf: 3335884 bytes, checksum: 89378cfa32c3cf46f97258266490ea63 (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Made available in DSpace on 2018-07-17T13:34:10Z (GMT).

Ferruginous features occur frequently in soils of the Araguaia river plain, where profiles can be verified completely dominated by these characteristics. The objective of this study was to evaluate the physical variations in the plinthite and petroplinthite, considering: a) the compressive strength and stability of plinthic materials present in soils of the Araguaia river plain under natural drying and in a forced ventilation oven for different periods; b) the influence of different solutions and periods of immersion in the reversibility of hardening of plinthite and petroplinthite of the Araguaia river plain soils, both with the purpose of subsidizing the classification of these features. The study was carried out in five soil profiles in the Araguaia river flood plain, in Luiz Alves, district in the municipality of São Miguel do Araguaia, Goiás. A soil profile was also studied in Terezópolis de Goiás, Goiás, in the João Leite riverside flood plain. Soils samples were collected with PVC cylinders, directly in the plinthic horizons. From these samples were extract subsamples of plinthite and matrix of the soil. Homogenous samples of petroplinthite were also collected and separated into subsamples. Two experiments were carried out: in the first, plinthite, matrix of the soil and petroplinthite subsamples were submitted to two types of drying: in the natural environment and in a forced ventilation oven, and in the second, plinthite and petroplinthite subsamples were submitted to five hydration treatments: natural water, calcium carbonate solution, sodium hydroxide solution, sodium hydroxide + sodium hexametaphosphate solution and acid solution. The periods determined for the evaluations were 10, 20, 40, 80 and 160 days. The degrees of dispersion and stability and the compressive strength were evaluated. For the plinthite and petroplinthite of the same profile, there is a great variability of behavior as to the applied compression strength, which is associated with the iron contents that compose them. The immersion of plinthite and petroplinthite in solutions composed of chemical agents affects the dispersion, and the plinthite is more susceptible to the alkaline agents, with reduction of the compressive strength exercised. |
