dc.description.abstractThis paper aims to evaluate geotechnically, chemically, mechanically, and hydraulically parameters of vegetal-based biomass ashes (VBA) and its soil incorporation with different ratios as potential liner material and soils strengthening. Composites were developed for testing with different ratios of VBA: soil, following 05:95, 10:90, 15:85, and 20:80%. All laboratorial testing program followed European standards. For geotechnical characterization, the following tests were performed for all mixtures, the soil and VBA: granulometric distribution, specific gravity and Atterberg limits. Chemical characterization was done by collecting pH values and energy-dispersive X-ray spectroscopy (EDS) parameters for elemental and oxides analysis. Also, x-ray diffraction (XRD) was done to evaluate all sample’s mineralogical description. In addition, mechanical analysis was conducted by analyzing expansibility, one-dimension consolidation through oedometer, and consolidated undrained (CU) triaxial test, along with falling head permeability for additional permeability analysis. Results have shown a finer granulometry and decrease of plasticity, 5% to non-plastic behavior, as higher amounts of VBA are introduced, exposing a filling-material behavior. EDS and XRD analysis indicate quartz, muscovite, orthoclase and calcite composition, and VBA could possibly have pozzolanic properties due to high silica-alum-ferric oxides amount. Mechanical parameters have shown a stabilization of VBA within the analyzed soil, exposing a slight reduction on settlements while increasing friction angle, 25–30º, and decreasing cohesion, 5–0 kPa. Permeability values have shown their feasibility for liners application, as found values characterizes all mixtures as low-permeability materials, especially introducing 5% of the residue into soil which values were below 10–9 m/s. Thus, the incorporation of VBA into soils paves a solid alternative for reusing this material in varied applications, as the analyzed soft soil has been geotechnically enhanced. Additional analysis, mainly pozzolanicity levels and leachability tests, can contribute for this on-going study to stablish VBA as a feasible material for the industry.pt_PT
