“…As shown in various studies, the strength property and tenacity of textile are important and needed to be improved for geotextile application due to the bearing capacity of soil and to protect from landslide disaster. [17][18][19][20] The maximum load of yarn directly impacts the fabric tensile strength. Therefore, PET yarns from plastic bottles have more potential to be used as a geotextilereinforced embankment.…”

This research article describes the preparation and characterization of geotextile-reinforced embankment made from yarns produced from polyethylene terephthalate bottles by the bottle cutter and stretching yarn prototype. The yarns produced from plastic bottles were weaved to obtain fabrics with different pattern structures. Yarns and fabrics samples were characterized including yarn number, yarn tensile, fabric thread density, fabric weight, fabric thickness, fabric breaking strength, and fabric bursting strength. The performance of the fabric samples as a geotextile was evaluated by direct shear test, California bearing ratio, and water permeability. The results show that the fabric pattern structure plausibly was the main factor for geotextile performance. The fabric samples with low thread density could develop both interlocking and interbedding mechanisms resulting in higher shear stress and California bearing ratio. Lastly, PLAXIS 2D program simulation with finite element method was used to estimate the possibility of the use of fabric samples as geotextile-reinforced embankment. It was found that the predicted safety factor of soil erosion with fabric sample could reach the value of one which is higher than the safety factor of the soil erosion without fabric sample.

“…There was no consensus on the effect of temperature on the soil strength. The mechanical properties of polymer materials were reduced with increasing temperature [30,[39][40][41][42] and increasing temperature may reduce the internal strength of GCL. Studies on fiber-reinforced soil mostly focus on the influence mechanism of the fiber-reinforced soil strength, the influence of freeze-thaw cycles on fiber-reinforced soil, and the influence of the fiber content and other factors [43][44][45][46][47].…”

Effect of Temperature on Internal Shear Strength Mechanism of Needle-Punched GCL

Needle-punched geosynthetic clay liner (NPGCL) has been widely used in landfills. The internal strength of the GCL changes with temperature variation, which affects its application in landfills. A large-scale temperature-controlled direct shear apparatus was developed to study the internal shear strength characteristics of GCL affected by temperature. The internal strength of the GCL was dependent on the bentonite, the fibers, and the interaction between the fibers and the bentonite. The influence of temperature on the internal strength of the GCL was mainly reflected in the displacement at peak strength. However, the peak strength was basically unchanged. The strength of the bentonite and the fibers-reinforced bentonite increased when the temperature increased. The tensile strength of needle-punched fibers decreased with increasing temperature. The peak strength displacement of the fibers-reinforced bentonite decreased with increasing temperature.

“…Several studies have demonstrated the effectiveness of using polypropylene fibers as a reinforcing material in improving the strength properties of soils [21,28,39,40,50,67,69,71]. Cai et al [14] reported that an increase in polypropylene fiber content caused an increase in the strength and shrinkage potential of soil.…”

The reuse of industrial and agricultural wastes is an alternative method to provide low-cost building materials for the construction industry and reduce the environmental pollutions. This study evaluates the feasibility of using a couple of waste materials including palm fiber, palm fiber ash and fiber bundles both individually and in combination with lime to improve strength characteristics of clayey sand. A series of laboratory tests were performed on samples cured for 7, 14, 28 and 56 days to investigate the compaction properties, unconfined compressive strength (UCS) and failure characteristics of the untreated and lime-treated clayey sand. The results demonstrate that the application of all the additives resulted in a noticeable increase in strength, and both treated and untreated specimens exhibited more ductile behavior. It was also revealed that the mixture of lime and fiber performed more impressively compared to that of lime and fiber individually and the UCS of the improved specimens depends on fiber length and curing period. Inclusion of the various proportions of palm fiber, palm fiber ash and lime increased the optimum moisture content (OMC) and decreased the maximum dry density (MDD), while the addition of fiber bundles decreased the value of MDD and OMC. Palm fiber ash was more effective in increasing the UCS of specimens, and fiber bundles had the most significant impact on the variations of compaction properties.
