Fiber reinforced soil

Fiber-Reinforced Soil Studies reported in the literature have shown that fiber reinforcement can improve the properties of soil, including the shear strength, compressive strength, bearing capacity, postpeak load strength retention, and the elastic modulus. Recycled-fiber-reinforced soil was studied by laboratory... 

The use of carpet waste for soil reinforcement has been shown to increase the triaxial compressive strength and ductility of soil. Field trials showed that shredded carpet waste fibers (to 70 mm long) can be blended into soil with conventional equipment. The availability of low-cost fibers from carpet waste could lead to wider use of fiber reinforced soil and more cost-effective construction.

Glass fiber-reinforced polymer (GRP) pipe is used for the transport of water and wastewater in pressure and non-pressure systems. This composite is composed of glass fiber and PP, PE, or PVC resins. These pipes are lightweight, corrosion resistant, and straightforward to install and have a long and effective service life and low maintenance costs. These features make GFR POCs, a strong candidate for piping applications in environments with acidic soil [51].

Fiber-reinforced polyesters - Their properties depend on the composition of the resin and the amount and distribution of the fibers. The composite composition determines the penetration of light as well as its mechanical and chemical properties. Thus, the use of tetrachlorophthalic acid increases the refractive index whereas the use of PMMA in place of styrene lowers the diffusion power and increases the transparency and stability of the product. Polyesters are slightly transparent to UV radiation and the penetration is further reduced or eliminated by UV absorbers. Transparency of reinforced polyesters to solar radiation is low and hence gives rise to a reduced temperature build-up. The greenhouse effect results from the opacity of this material to radiation emitted by the soil. 

Concrete and soil are dealt with in great quantities in construction. Studies have shown that the properties of these materials can be enhanced by fiber reinforcement. A brief review is provided in this article on the advantages of fiber reinforcement of concrete and soil. Laboratory and field studies using carpet waste fibers for concrete and soil reinforcement are described. 

The increase of the load-carrying capability of soil due to fiber reinforcement could result in significant savings in construction cost and time. An increase in allowable slope angle would reduce the space and the amount of soil needed for a slope. As illustrated in Fig. 14.2, the reduction of soil volume (V) can be calculated from ...
