Stress–strain behavior of a silty soil reinforced with polyethylene terephthalate (PET)

Behavior of cement-stabilized fiber-reinforced pond ash, rice husk ash–soil mixtures

“…A number of research studies on fiber-reinforced soils have recently been carried out through triaxial tests, unconfined compression tests, CBR tests, direct shear tests, and tensile and flexural strength tests (Freitag, 1986;Maher and Gray, 1990;Al-Refeai, 1991;Fatani et al, 1991;Maher and Ho, 1994;Ranjan et al, 1996;Nataraj and McManis, 1997;Consoli et al, 1998Consoli et al, , 2002Consoli et al, , 2005Santoni et al, 2001;Kumar et al, 2005;Casagrande et al, 2006Casagrande et al, , 2007aCasagrande et al, , 2007bKim et al, 2008;Park, 2008;Bera et al, 2009;Fatahi et al, 2012;Divya et al, 2014;Li et al, 2014;Anggraini et al, 2014;Botero et al, 2015). One of the primary advantages of randomly distributed fibers is the absence of potential planes of weakness that can develop parallel to oriented reinforcement (Maher and Gray, 1990).…”

Feasibility of using rubber waste fibers as reinforcements for sandy soils

“…In the first technique, the shear tensile strength in soils surrounding the reinforcement increases, which promotes the appearance of shear plans at the inclusions and affects both local and global stability of earth-based structures, especially when several layers of continuous reinforcements exist. However, in the second case, randomly distributed fibers reduce the formation of weak planes, which could increase the long-term stability of reinforced earth-based structures [3]. Reinforcing soils with short fibers has been increasingly investigated by researchers both in theory and in practice due to its advantages.…”

“…Tang et al [20] have reported that using randomly distributed fiber as reinforcements exhibits several advantages in comparison with planar geosynthetics including: discrete fibers can be simply added and mixed with soil, in much the same way as cement, lime and other additives; randomly distributed fibers can limit the potential planes of weakness that can develop parallel to conventional oriented reinforcement, and provide isotropic increase in the strength of the soil composite. Randomly distributed fibers can be distinguished by its material; in fact, many types of fibers are used by researchers for reinforcing both granular and cohesive soils, such as polypropylene fibers [8,20], vegetal fibers [12], polyethylene terephthalate fibers [3], linen fibers [10] and glass fibers [1].…”

Effect of reinforcement fibers on the collapse potential of clayey sands

“…Hamidi and Hooresfand (2013) used the conventional triaxial compression tests to determine the effect of cement and polypropylene fiber reinforcement on sand, the addition of fibers increased peak and residual shear strength of cement treated soil and changed its brittle behaviour to a more ductile one. Botero and Ossa (2015) studied the mechanical behaviour of a silty soil that was reinforced with randomly distributed PET fibers. The results indicated that the reinforced specimens presented increase of shear strength that was associated with the increasing quantities of the PET fiber.…”
