    Análisis del uso de ceniza de la hoja de Agave Americana (Cabuya) para la estabilización de suelo

    Soil is a fundamental component in civil engineering, since it provides a basis for the construction of highways, rural roads and other infrastructure. Therefore, it is essential to carry out detailed studies to evaluate its physical and mechanical characteristics. In case it does not meet the technical requirements, it is necessary to consider alternatives, such as its replacement or the addition of elements or materials that improve its mechanical properties. The influence of American agave leaf ash (CHA) on the physical and mechanical properties of three soil samples was analyzed. Quantitative methodology was used, which included data collection and laboratory tests, such as moisture content, granulometric analysis, determination of specific gravity, Atterberg limits, modified Proctor test and CBR test. The results indicated that, for sample M1 (poorly graded sandy soil, SP), from Cevallos canton, the CBR value increased to 43.16 percent with the addition of 5.22 percent CHA, although this improvement was not representative. For sample M2 (silty soil, SM), collected in the Ambato canton, the CBR increased to 39.32 percent, with the addition of 16.92 percent CHA, showing a substantial improvement. Finally, sample M3 (high plasticity clayey soil, CH), taken from Puyo canton, reached a CBR value of 22.35 percent with the addition of 24.84 percent CHA, reflecting a significant improvement in its mechanical properties. In conclusion, the inclusion of agave leaf ash improves the mechanical properties of certain types of soils. However, in sandy soils (sample M1) the increase is not significant enough, while for silty and clayey soils (M2 and M3), it is considered an alternative for their stabilization.
