Effect of Coir Fiber on the Stress–Strain Behavior of a Reconstituted Fine-Grained Soil

Enhancing compressive strength of soil using natural fibers

“…Addition of discrete coir fibers by about 1-2% by weight in the soil increases strength and stiffness of tropical soil [48]. Variation in the length of fibers and content in the soil results in improvement in strength characteristics of soil [49]. Therefore length of fibers plays a significant role in compressive strength improvement of soil.…”

Shear Strength Behaviour of Clay Reinforced with Treated Coir Fibres

“…The results of the tests and the model were quite comparable. The unconfined compressive strength test and unconsolidated undrained triaxial test on low compressible clay reinforced with coir fibres were reported by [9]. The results of the unconfined compressive strength test with the addition of 30 mm and 15 mm long coir fibres to the clay indicated a decrease and an increase in its unconfined compressive strength, respectively.…”

“…Coir is useful in different applications as reinforcing material in soil due its high lignin content [5]. Many researchers [1][2][3][4][5][6][7][8][9][10] have shown that coir fibre reinforcement can significantly improve the engineering properties of soil. But the presence of the pectins, lignin, hemicellulose, silica and pith on the surface of these fibres results in poor interaction with the soil [3].…”

Loading capacity strengthening to cement-stabilised crushed gravel using reinforced wire mesh

“…The performance of fibre-reinforced clay soil implies that ultimate bearing capacity is increased and settlement is decreased (Maheshwari, Desai, & Solanki, 2011). Test results of coir fibre to reinforce fine-grained soil indicate that coir fibre improves the stress-strain characteristic of mixed soil (Dasaka & Sumesh, 2011).…”
