Resumo: | Tropical soils have mineralogical peculiarities resulting from their formation that give them unique structural behaviors. They are divided into lateritic and saprolitic soils, and both have unique characteristics when compared to other soil occurrences. One of the characteristics of interest from these soils is the plasticity, measured by the Atterberg limits test. Such limits are widely used in geotechnics and, in determining the moisture values, it is observed that the soil changes from a physical state to the next (solid, semi-solid, plastic and liquid). A method capable of improving soil properties, such as plasticity, is stabilization with Portland cement. In addition to the plasticity-reducing effect, this additive also promotes a significant gain in strength. The objective of this study is to compare the Atterberg limits of a pure lateritic soil with others that are mixed with Portland cement percentages in different granulometric intervals. For this purpose, a lateritic soil and contents of 5% and 8% of Portland cement of high early strength were used, in relation to the total mass. The experimental program involved the tests of granulometric analysis, specific gravity of the grains, liquid limit and plastic limit of the pure soil. Liquid limit and Plastic limit tests were performed at different granulometric intervals, starting from the #40 sieve, in pure soil and soil-cement samples. The results obtained showed a tendency of increase in the Atterberg limits, as the grain size is reduced. A reduction in plasticity was observed with the addition of the additive, as long as conditions are promoted for sufficient hydration of the cement grains. In addition, for smaller grain sizes, greater must be the amount of additive to reduce plasticity. |

Estes se dividem em solos lateríticos e saprolíticos, e ambos possuem características únicas em comparação com outras ocorrências de solo. Uma das características de interesse desses solos é a plasticidade, mensurada através dos ensaios de limites de Atterberg. Tais limites são amplamente utilizados na geotecnia e, na determinação dos seus valores de umidade. Observa-se que o solo muda de um estado físico para o próximo (sólido, semissólido, plástico e líquido). Um método capaz de melhorar as propriedades do solo como, por exemplo, a plasticidade, é a estabilização com uso de cimento Portland. Além do efeito redutor de plasticidade, esse aditivo ainda promove um sensível ganho de resistência. O objetivo deste trabalho é comparar os limites de Atterberg de um solo laterítico puro e misturado a porcentagens de cimento Portland em diferentes intervalos granulométricos. Para tal, foi utilizado um solo laterítico e teores de 5% e 8% de cimento Portland de alta resistência inicial, em relação à massa total. O programa experimental envolveu os ensaios de análise granulométrica, massa específica dos grãos, limite de liquidez e limite de plasticidade do solo puro. Os ensaios de limite de liquidez e limite de plasticidade foram realizados em diferentes intervalos granulométricos, a partir da peneira #40, em amostras de solo puro e solo-cimento. Os resultados obtidos mostraram a tendência de aumento nos limites de Atterberg, conforme se reduz o tamanho dos grãos. Foi observada uma redução de plasticidade com a adição do aditivo, contanto que se promovam condições para haver suficiente hidratação dos grãos do cimento. Além disso, para menores tamanhos dos grãos, maior deve ser a quantidade do aditivo para reduzir a plasticidade.São Cristóvão, SEporEngenharia civilEnsino superior (UFS)Solos lateríticosLimites de AtterbergEstabilização de solosCimento PortlandGeotécnicaLateritic soilsAtterberg limitsSoil stabilizationENGENHARIAS::ENGENHARIA CIVIL::GEOTECNICAAnálise dos limites de Atterberg em intervalos granulométricos de um solo laterítico puro e aditivado com Cimento Portlandinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/bachelorThesisUniversidade Federal de Sergipe (UFS)DEC - Departamento de Engenharia Civil – São Cristóvão - Presencialreponame:Repositório Institucional da UFSinstname:Universidade Federal de Sergipe (UFS)instacron:UFSinfo:eu-repo/semantics/openAccessLICENSElicense.txtlicense.txttext/plain; charset=utf-81475https://ri.ufs.br/jspui/bitstream/riufs/18552/1/license.txt098cbbf65c2c15e1fb2e49c5d306a44cMD51ORIGINALLeandro_Augusto_Morais_Souza.pdfLeandro_Augusto_Morais_Souza.pdfapplication/pdf1917548https://ri.ufs.br/jspui/bitstream/riufs/18552/2/Leandro_Augusto_Morais_Souza.pdf758c9356fb106b656cba47fb5528a36eMD52riufs/185522023-10-20 09:03:33.141oai:ufs.br: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Repositório InstitucionalPUBhttps://ri.ufs.br/oai/requestrepositorio@academico.ufs.bropendoar:2023-10-20T12:03:33Repositório Institucional da UFS - Universidade Federal de Sergipe (UFS)false |
