“…After fibers are added to sandy soil, they form an interlocking network structure within the soil, which notably improves the mechanical strength of sandy soil [16]. Jairaj et al [17] used naturally grown sisal fibers to improve sandy soil and found that the addition of the fibers significantly improved the mechanical strength of the soil, with an optimal sisal fiber content of 2%. Xu et al [18] conducted direct shear tests on polypropylene-, glass-, and basalt-fiber-reinforced sand using large-scale direct shear tests to compare and study the shear strength and shear expansion phenomenon of reinforced sand under different fiber-content conditions.…”

Natural sand has a loose and porous structure with low strength, and is prone to many geoengineering problems that cause huge losses. In this study, an organic polymer-polymer-fiber blend was used to improve the strength of sand. Using a series of laboratory and numerical simulation tests, researchers have investigated the microdamage behavior of an organic polymer and fiber-treated sand in various types of mechanical tests and explored the improvement mechanism. The results showed that the polymer- and fiber-treated sand enhanced the integrity and exhibited differential damage responses under different test conditions. The increase in polymer content induced uniform force transfer, leading to a wider range of particle motion and crack initiation, whereas the fibers adhered and confined the surrounding particles, inducing an arching force chain and dispersive/buckling cracking. Polymer- and fiber-treated sands increased their energy-carrying capacity and improved their energy release, which affected the damage characteristics. Organic polymers, fibers, and sand particles were wrapped around each other to form an effective interlocking structure, which enhances the integrity and mechanical properties of sand. This study provides novel ideas and methods in the polymer-fiber composite treatment of sand in the microscopic field.
