    Análisis comparativo del uso de ceniza de la cascarilla de arroz para la estabilización de suelo
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2024-02) Portero Panimbosa, Christian Javier; Bayas Altamirano, Myriam Marisol
    This research arises as an alternative in soil stabilization by using rice husk ash (RHA) to generate a positive impact on the environment. The rice industry generates a huge amount of agricultural waste that are not used, such as rice husk, which, when it is incinerated under controlled temperatures exceeding 500 degrees Celsius, produce ash rich in silica. To assess the influence of RHA on the mechanical properties of soils, one sample of soil was taken from three different locations, tests like modified Proctor and CBR were conducted initially on natural soil samples and subsequently with the replacement of RHA in different proportions (15, 25, and 35 percent). The data revealed that the inclusion of RHA led to an increase in the optimum moisture content and a decrease in maximum dry density, also showed a significant improvement in CBR, where, for sandy soil SM with the addition of 26.80 percent of RHA, the CBR increased by 18.30 percent, for sandy silty soil ML with the addition of 12.30 percent of RHA, the CBR increased by 12.55 percent, and for clayed soil CH with the addition of 26.00 percent of RHA, the CBR increased by 11.10 percent. Consequently, the findings from this experimental project could serve as a starting point for the development of new methods and materials for soil stabilization.
