“…[4] reported that the optimum width of the geocell is 4.9B, beyond this width the improvement was found to be very marginal. Reference [12] reported the optimum width of the geocell was 4B in his study for jute geocell.…”

“…The lateral outspreading of the infill material is limited due to the all-around confinement offered by the geocell. The beneficial results of the geocell reinforcement were reported by many researchers by using field studies and experimental studies [6][7][8][9][10][11][12]. Although, for the design of complex geotechnical problems only experimental and field studies are not sufficient.…”

The usage of geocell reinforcement for foundations supported on weak soil has been increased these days. The purposed study uses FEM-based ABAQUS software to analyse the behaviour of square footing supported on geocell reinforced sands subjected to static vertical loading. Numerical analysis was performed to find the optimum combination of the different geometric parameters of the geocell reinforcement. Three distinct types of sands were employed in the study with relative densities of 30%, 50%, and 70%. The geometric parameters of the geocell, such as the placement depth of geocell (u), the width (b), and the height (h) of the geocell, were modified in relation to the footing width (B) to access the optimum combination ratios. The inclusion of the geocell reinforcement increases the load-carrying capacity up to 5-6 times compared to unreinforced sand. The results obtained from the numerical analysis were intended to correlate well with the experimental data available in the literature.

“…Recent concerns over environmental sustainability emphasize research towards the development of eco-friendly materials for engineering applications including ground improvement [1]. One of the possible approaches to achieve sustainability is the replacement of artificial geotextiles with natural geotextiles to reduce associated CO 2 emissions [2].…”

“…Polymeric geosynthetics are having a long life and better durability for improving the unpaved roads but these are the sources of creating nuisance to an environment at end-of-life span [3]. Natural fibers such as jute, coir, and hemp are normally implemented to replace synthetic fibers as reinforcing agents in soil owing to their easy accessibility, reproducibility, low cost, and good biocompatibility [1,4,5]. Immediate protection against soil erosion can be achieved through wool geotextile which is slow at biodegradation and further promotes vegetation for full slope protection [6].…”

The application of natural fibers for improving the strength of soft soil is gaining recent global popularity to achieve sustainable development. However, the biodegradability of natural fibers within 6-12 months is the main source of a hindrance towards its practical implementation. Treatment of natural fibers with antimicrobial chemicals, plant-derived oils, acetylation, and bitumen coating results in improving the durability of natural fibers, but these methods are costly and may cause leaching. The current work suggests a unique treatment approach for natural jute geotextiles that involves treating these geotextiles with an alkali-activated binder (AAB) to improve their strength and durability. Fly ash, an aluminosilicate-rich industrial waste, reacts with a sodium silicate and sodium hydroxide-based activator solution to form AAB. The water-to-solids ratios (w/s) are maintained at 0.30, 0.35, 0.4, 0.45, and 0.50 for treatment of the fibers. The untreated and treated natural geotextiles are subjected to different durability tests including soil burial, compost burial, exposure to acids and alkalis, and hydrolysis of water for three different periods of 30, 60, and 90 days. The durability performance is assessed by analyzing the surface texture, surface morphology, change in chemical bonds, weight loss, tensile strength, and elongation at failure (fiber breaking). It is observed from the durability studies that the AAB treatment makes the jute geotextile harder and more resistant to exposure to different chemicals. It is also been determined that jute coated with an AAB of 0.35 w/s ratio degrades the least.

“…There are a number of research studies on the efficiency of jute as two-dimensional geotextile or geogrid [16][17][18][19][20]. Muthukumar et al [21] performed model footing tests on sand bed with geocells made from woven jute geotextiles and the bearing capacity of sand was found to increase 3.5 times compared to unreinforced sand. However, a comparison with HDPE geocell or analytical modelling was not attempted.…”

This paper presents the performance of soil bed reinforced with jute and sisal geocells compared to HDPE geocells. The bearing pressure-settlement behaviour of the soil bed reinforced with natural geocells, soil bed reinforced with HDPE geocells and of unreinforced soil bed are discussed. The soil bed reinforced with jute cell and sisal cell showed a uniform increase in the settlement with increase in the applied pressure. The soil reinforced with HDPE geocell, however, showed a sudden rise in the settlement at higher pressure. Sisal mat used for developing the geocell was found to have greater tensile strength, followed by jute mat over HDPE material. Soil reinforced with sisal cells could bear larger stresses at lower strain compared to HDPE geocell. Analytical studies on jute and sisal geocells also were carried out considering the load transfer mechanism of geocell-reinforced soil.
