Resumo: | The inadequate disposal of industrial and mining solid wastes have become a potential issue, especially because of the negative impacts on the environment and human health. This occurs mainly through the contamination of subsurface soil and groundwater by wastewaters, which are often of acidic constitution. To prevent situations like this, the study and improvement of efficient containment techniques for wastes generated in potentially polluting activities has become necessary and opportune. In this way, this work was aimed to investigate the mechanical and hydraulic behavior of two different compacted soils, with and without the addition of Portland cement (0 and 2%), submitted to the action of a sulfuric acid solution (2% volume concentration) and to a constant static vertical load (280 kN/m2), aiming at its prospective application as containment barrier. The experimental program comprised a few permeability tests, performed in an instrumented rigid-wall permeameter, during which the variations in hydraulic conductivity, shear deformation modulus, and settlement were measured and analyzed. In addition, for the specimens percolated with the acidic solution, the split tensile strength was also determined. The results showed that the hydraulic conductivity increased with cement addition and decreased with the acidic percolation. Regarding the mechanical behavior, the acidic percolation caused, almost instantaneously, an increase in settlement rate and a reduction in stiffness, although the trend of stabilization observed afterwards, until the end of the tests. |

Isso ocorre principalmente através da contaminação dos solos e mananciais hídricos pelo lixiviado gerado, muitas vezes de características ácidas. Para prevenir situações como esta, faz-se necessário o estudo e o aperfeiçoamento de técnicas eficientes para contenção de resíduos gerados em atividades potencialmente poluidoras. Desta forma, este trabalho tem como objetivo investigar o comportamento mecânico e hidráulico de dois solos compactados, um argiloso e outro arenoso, com e sem adição de cimento (0 e 2%), quando submetidos à ação de uma solução de ácido sulfúrico (concentração volumétrica de 2%) e à carga vertical estática constante (280 kN/m2), visando a sua aplicação em barreiras impermeáveis de contenção de resíduos. O programa experimental consistiu na realização de ensaios de percolação, em permeâmetro de parede rígida instrumentado, durante os quais foram medidas e analisadas as variações do coeficiente de condutividade hidráulica e do módulo de deformação cisalhante, além dos recalques, e ensaios de resistência à compressão diametral. Os resultados mostraram que a condutividade hidráulica aumentou quando adicionado cimento e diminuiu com a percolação ácida. Quanto ao comportamento mecânico, a percolação ácida causou, quase que instantaneamente, o aumento na taxa de recalque e a redução da rigidez, embora a tendência de estabilização observada posteriormente até o final dos ensaios.Submitted by Mariana Freitas (marianafreitas@upf.br) on 2018-06-06T19:59:43Z No. of bitstreams: 1 2015fFancieleNolldaSilva.pdf: 6148933 bytes, checksum: c64ac4846ec0c6ff8e847dce2feba517 (MD5)Made available in DSpace on 2018-06-06T19:59:43Z (GMT).

The inadequate disposal of industrial and mining solid wastes have become a potential issue, especially because of the negative impacts on the environment and human health. This occurs mainly through the contamination of subsurface soil and groundwater by wastewaters, which are often of acidic constitution. To prevent situations like this, the study and improvement of efficient containment techniques for wastes generated in potentially polluting activities has become necessary and opportune. In this way, this work was aimed to investigate the mechanical and hydraulic behavior of two different compacted soils, with and without the addition of Portland cement (0 and 2%), submitted to the action of a sulfuric acid solution (2% volume concentration) and to a constant static vertical load (280 kN/m2), aiming at its prospective application as containment barrier. The experimental program comprised a few permeability tests, performed in an instrumented rigid-wall permeameter, during which the variations in hydraulic conductivity, shear deformation modulus, and settlement were measured and analyzed. In addition, for the specimens percolated with the acidic solution, the split tensile strength was also determined. The results showed that the hydraulic conductivity increased with cement addition and decreased with the acidic percolation. Regarding the mechanical behavior, the acidic percolation caused, almost instantaneously, an increase in settlement rate and a reduction in stiffness, although the trend of stabilization observed afterwards, until the end of the tests. |
