Resumo:
This paper presents the experimental study of the behavior of a sandy soil and a clay soil, reinforced and unreinforced with sugarcane bagasse ash and rice husk ash, by performing physical and chemical characterization tests and direct shear tests. The aim is to establish patterns of behavior that may explain the influence of the addition of ashes, relating them to the shear strength parameters and soil deformation. The tests were carried out on samples with concentrations ranging from 5-20 percent. Through the results, it was possible to conclude that the inclusion of sugarcane bagasse ash, to clay and sandy soils under study, proves viable, since it resulted in improved strength parameters or did not cause significant alterations. For the rice husk ash in mixtures with sandy soil, the application was not feasible, since for both ash contents there was a decrease in the friction angle and no increase in the cohesion. In blends with clay soil, the application of the same ash proved to be feasible, given that its application resulted in improvement of resistance parameters. As for the ash content for mixtures containing clay soil, it was found that the best performance was obtained with 20 percent content for mixtures with both ashes. For mixtures with sand, as there was not a proportional increase in resistance with increasing content of ash it was difficult to determine an optimal ash content to be used. The results of this study generally were satisfactory and met the initial proposed objectives in relation to soil-ash behavioral research for use in geotechnical works.
