Effect of Freeze–Thaw Cycles on Black Cotton Soil Reinforced with Coir and Hemp Fibres in Alkali-Activated Binder

Compressive and Shear Strengths of Coir Fibre Reinforced Activated Carbon Stabilised Lateritic Soil

“…However, the reinforced specimens illustrate a ductile behaviour, by adding 0.5% coir fibre to AC specimens. Fibre additions in the AC specimens enhance the soil strength by tightly enclosing the particles around the fibres as a bridge surface [46]. The high strength of AC depends on soil-porosity reduction.…”

Effect of Polypropylene Macro Fiber on Geotechnical characteristics of Black Cotton Soil: An Experimental Investigation and Correlation Analysis

“…Tharini et al 2020 [22] found 15.39 kN/m 3 and 34% for MDD and OMC, respectively, for 0.5% replacement of PPF with BC soil. Syed et al 2020 [27] 19.8 kN/m 3 and 17.2% for 0.4% replacement for MDD and OMC respectively for coir fiber with BC soil, 20.2kN/m 3 and 17% for 0.4% replacement for MDD and OMC respectively for hemp fibers with BC soil, Kamya and Kumar 2020 [29] found 15.49kN/m 3 and 23% for 0.5% replacement, 15kN/m 3 and 27% for 1% replacement, and 15.20 and 25% for 1.5% replacement for MDD and OMC respectively for human hair fiber with BC soil. Ganja 2020 [31] found 14.6kN/m 3 and 28% for 0.5% replacement, 14.04kN/m 3 and 30% for 1% replacement, and 12.54 kN/m 3 and 32% for 1.5% replacement for MDD and OMC respectively for coir fiber with BC soil.…”

“…Syed et al 2020 [27] ,569kN/m 2 for 0.4% replacement for coir fiber with BC soil, 572kN/m 2 for 0.4% replacement for hemp fibers with BC soil, Kamya and Kumar 2020 [29] found 147kN/m 2 for 0.5% replacement, 274 kN/m 2 for 1% replacement, and 245 kN/m 2 for 1.5% replacement of human hair fiber with BC soil. Kesavan and Rajalingam 2019 [30] found 118kN/m 2 for 0.5% replacement of arecanut fibers with BC soil.…”

Special Issue on “Materials and Processes for Ground Engineering Infrastructure”

“…These powder forms are originated from waste materials and have less alternative usage compared with fibres, which are agricultural residues and have alternative use in food chain of animals and also in textile manufacturing in developing countries. The requirement of percentage content of powder form materials from 7.5% for waste marble powder [1] to 30% for biochar powder [5] to achieve peak performance is much higher than that of fiber content (within 1% mainly [1]). This could be related to tensile strength of fibre itself, which enhances mobilization of shear forces within amended soil specimens.…”

“…The topics of this special issue cover various aspects, including laboratory testing and evaluation of material properties, field monitoring of ground improvement practices, data processing techniques, theoretical and numerical modelling, and supporting technologies and methodologies in ground engineering infrastructure. This special issue contains several papers dealing with the usage of new materials ranging from fibres to powderbased materials (waste marble, eggshell, flyash, and biochar) and pre-fabricated drains from different perspectives (freeze-thaw, dry-wet resistance, dynamic shear, compressive and tensile loading as well as gas flow) [1][2][3][4][5][6][7][8][9][10][11][12]. Coir and hemp fibres along with fly ash based alkaline binders are found to have profound effect on geotechnical properties of soils, such as tensile strength under the condition of freeze-thaw cycles [1].…”
