“…Hence they can not increase the strength of the reinforced soil. Ahmad et al 7 carried out experimental tests on randomly reinforced soil samples and showed that the strength parameters decreased by increasing the fiber length. They stated that the reduction of strength parameters may be due to the non-uniform distribution of fibers in the soil sample or increasing the number of fibers in the horizontal plane in the sample.…”

Randomly reinforced cohesive soils can be used as construction material in many civil engineering projects. These materials may be subjected to compressive, tensile or flexural stresses in their life. The presence of stabilizing agents or fibers may affect their resistance against various loads. In this work a clay soil was reinforced randomly at four different lengths of fiber ((10, 15, 20 and 25 mm) [0.394, 0.591, 0.788 and 0.985 in]) with fiber inclusions of 0.5 and 1%. Reinforced soil-cement samples were also prepared with 8 and 10% cement and reinforced similar to the soil. Unconfined compressive and tensile strength tests were carried out on the prepared samples. The results show that the compressive strength is increased with fiber length up to about 10 mm (0.394 in). When length of fiber is larger than 10 mm (0.394 in), the compressive strength is still increased but with a slow rate. The results for the reinforced soil-cement samples indicate that for a given fiber and cement content increasing the length of fiber has no significant effect on the strength of the sample.The tensile strength of reinforced soil is increased by increasing the fiber inclusion and length of fiber. For the reinforced soil-cement samples the tensile strength is increased with increasing fiber content, length of fiber, percent of cement and curing time.

“…The inclusion of fibers significantly changes the failure mechanism by preventing the formation of tension cracks 5 . Since 1970s investigators have studied the mechanical behaviour of this kind of soil reinforcement through conducting appropriate tests [6][7][8][9][10][11][12][13] .…”

“…The previous studies describe that inclusion of OPEFB fibres can significantly increase the peak shear strength of silty sand soil (Ahmad et al, 2010). The fibre content increment leads to increasing the shear strength and consequently stabilized the reinforced soil.…”

Abstract. Fiber reinforced soil is an effective and reliable technique for improving strength and stability of subgrade soil. Many studies have been conducted to investigate the influence of randomly distribution fiber inclusions in soil. Agricultural waste fiber was chosen as it is cheap, locally available, bio-degradable and eco-friendly. For this study, coir fiber and palm oil fiber will be implemented. Three types of soil with different properties were used to be mixed with both fibers. The present work will be focused on the influence of 1% waste materials into soils in terms of physical, chemical, morphological and mineralogical properties of waste-soil mixture and its relationship to the shear strength properties. Test result indicates that with addition of both fibers, the optimum moisture content (OMC) increased and the maximum dry density (MDD) decreased. Fibers inclusion can significantly decrease and increased the cohesion and internal angle of friction of soils, respectively.
