Strength and microstructural behaviour of sand Kaolin mixtures stabilized with terrazyme and Xanthan gum Geethu Thomas, Ripsa Rani Nayak, Navneet Kumar Gupta, Gali Madhavi Latha Scientific Reports, 2026 This study evaluates the efficacy of TerraZyme (bioenzyme) and Xanthan Gum (biopolymer) in improving the mechanical behavior of Sand-Kaolin mixtures for sustainable soil stabilization. Sand and 15% Kaolin blend were treated with different additive dosages, and the specimens were evaluated via static triaxial testing under unconsolidated undrained conditions, the results are supported by further microstructural and chemical spectroscopy analyses. The optimum dosages found to be 0.075 mL/kg for TerraZyme and 1% (w/w) Xanthan Gum for increasing the shear strength up to 2.5 times after curing for 30 days. TerraZyme facilitated biochemical interaction, forming cemented bonds between sand particles and Xanthan Gum connected the particles via a polymeric network improving interparticle bonding. The results reveal that the use of bioenzymes and biopolymers in stabilization is an environmentally friendly, low-carbon option for ground improvement compared to that of chemical stabilizers.
Liquefaction response of geocell-reinforced sand beds Prerana Krishnaraj, Gali Madhavi Latha Soil Dynamics and Earthquake Engineering, 2026 The evolvement and wide usage of geocells in numerous soil reinforcement applications necessitate the understanding of the liquefaction resistance of the geocell-reinforced soils. This paper investigates the liquefaction resistance of geocell-reinforced sand beds through laboratory shaking table model studies and numerical studies. To scale down the dimensions and mechanical strength of geocells for 1- g shaking table model tests, geocells used in the experiments were fabricated using 3D-printed polypropylene sheets. Sand beds were subjected to ground shaking of different intensities. At an input acceleration of 0.2 g , the inclusion of the geocell layer enhanced the loading cycles required for the liquefaction by 120 % and the beneficial effects of geocell increased at higher base accelerations. To complement the shaking table model tests and to understand the role of geocells on the liquefaction resistance of sand beds in the field, numerical studies were conducted using FLAC 3D . From numerical studies, the depth of improvement, where the influence of the geocell on the development of the pore water pressure is prominent, is quantified. The depth of improvement is found to be a function of the depth of placement of the geocell layer, aspect ratio, stiffness of geocells, and the relative density of the sand.
Experimental investigation of the effect of grain morphology on packing density of granular assemblies K.V. Anusree, Gali Madhavi Latha EPJ Web of Conferences, 2025 The physical and mechanical properties of granular media at the macro scale are greatly influenced by the morphology of its grains at the micro-scale. The morphology of grains is a multi-level property, with the morphological features at each level being independent. Thus, while understanding the effect of the granular morphology on the macro scale behaviour of granular media like sands, it becomes imperative to understand the influence of individual morphological features. The current study investigates the effects of macro and meso-scale morphological properties of grains on the packing density of granular media. Virtual granular assemblies with controlled shape parameters are generated using the spherical harmonics algorithm. The shapes of the grains in the virtual granular assemblies are varied to understand the effects of individual morphological properties at different levels. Polyjet 3D printing is employed to generate synthetic grains from virtual grain assemblies. Further, experimental investigations are performed using these synthetic grains with controlled shapes to estimate their minimum and maximum packing density. The effects of particle form and roundness on the packing density are analysed. The results highlight that the particle shape significantly affects the packing density of granular media at loose and dense states with packing density values decreasing with a decrease in roundness and regularity.
