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.
