“…The results plotted in Figure 2 shows that after 14days curing period, the UCS of samples mixed with 5% cement increases from 707 kPa at 0% fibre content to 957 kPa) and 964kPa at 0.4% polypropylene and 0.8% glass fibre contents respectively. The increase in UCS with increasing cement and fibre contents agrees with the results of Chore and Vaidya, and Chenge et al [44,45]. Over time, the high strength observed in the samples contaning 5%PC and 0 to 0.8% fibre is due to the formation of calcium silicate hydrate gel (C-S-H gel) as expected.…”

Clayey soils endure adverse changes in strength and volume due to seasonal changes in moisture content and temperature. It has been well recognised that high cement content has been successfully employed in improving the mechanical properties of clayey soils for geotechnical infrastructural purposes. However, the environmental setbacks regarding the use of high cement content in soil reinforcement have necessitated the need for a greener soil reinforcement technique by incorporating industrial by-product materials and synthetic fibres with a reduced amount of cement content in soil-cement mixtures. Therefore, this study presents an experimental study to investigate the mechanical performance of polypropylene and glass fibre-reinforced cement-clay mixtures blended with ground granulated blast slag (GGBS), lime and micro silica for different mix compositions and curing conditions. The unconfined compressive strength, linear expansion and microstructural analysis of the reinforced soils have been studied. The results show that an increase in polypropylene and glass fibre contents caused an increase in unconfined compressive strength but brought on the reduction of linear expansion of the investigated clay from 7.92% to 0.2% at fibre content up to 0.8% for cement-clay mixture reinforced with 5% Portland cement (PC). The use of 0.4–0.8% polypropylene and glass fibre contents in reinforcing cement-clay mixture at 5% cement content causes an increase in unconfined compressive strength (UCS) values above the minimum UCS target value according to American Society for Testing and Materials (ASTM) 4609 after 7 and 14 days curing at 20 °C to 50 °C temperature. Therefore, this new clean production of fibre-reinforced cement-clay mixture blended with industrial by-product materials has great potential for a wide range of applications in subgrade reinforcement.

This study examines the effect of polypropylene fiber on the flexural strength properties of lightweight foam mixed soil (LFS). The flexural properties of LFS comprising different proportions of polypropylene fiber (58 mm) at different volume fractions (0.5%, 0.75%, and 1%), three different cement contents of 100, 150, and 200 kg/m3, and densities of 0.8, 1.0, and 1.2 g/cm3 were thoroughly investigated. The flexural performance of LFS according to ASTM C1609 was achieved after 28 days of aging. The results show that the flexural characteristics of LFS could be enhanced by fiber additives, as indicated by the increase in the flexural/residual strength and equivalent flexural strength ratio. The flexural performance is also related to the mixing components, including the density and cement content. For the toughness behavior, the equivalent flexural strength ratio reached up to 100%, which could be achieved with the strain-hardening specimens. The fiber inclusion is more efficient with an increase in the density and cement content of specimens as shown by the overall rating of the flexural performance.

“…In addition to concrete, synthetic or natural fibers can be used for soil stabilization. The synthetic fibers presently being used include strands of waste tires [1], nylon fibers [2], polypropylene fibers [3][4][5], glass fibers [6], and basalt fibers [7]. The emerging natural fibers include coir fiber [8], wheat straw, barley straw, wood shavings [9], bamboo fiber [10], and oil palm empty fruit bunches (OPEFBs) [11,12].…”

“…Soil stabilization with fiber is influenced by many factors, including the amount of fiber [1,2,[4][5][6][7]9,10,12,15,16], fiber length [5,7,10,15], moisture contents of the samples [16], fiber characteristics [6,9,12,17], fiber diameter [10], soil properties [2,17], and soil stress [1,8,17]. In some cases, natural fibers can absorb sufficient quantities of water [9,18,19].…”

Natural fibers are already being used to stabilize the soil. However, the exact mechanism by which natural fibers improve the shear strength of soil is still not clear, and it varies according to the morphology of each fiber. Its durability in the soil is also an important issue in the use of natural fibers for soil stabilization. This study focused on the strength and durability of oil palm empty fruit bunch (OPEFB) fiber as a stabilizing material for soft clay. The durability was determined according to the changes in tensile strength and friction of the soil after a certain period. The clay was obtained from Banyu Hirang in South Kalimantan. The OPEFB fiber was obtained without further treatment from a palm oil processing plant. Tensile, soil-fiber friction, and unconfined compression tests were conducted for mixtures of fiber and soil. Preparations were made for each test with the same duration and conditions (1, 7, 14, 28, and 90 days) in closed and open conditions. The results showed that the average tensile strength of the fiber before use was 101 MPa. This value decreased sharply after 14 days in the soil, leaving a strength of 35.71 MPa in the open condition and 23.89% in the closed condition on the 90th day. The soil-fiber friction increased with increasing time, reaching 0.15 MPa in both conditions from the initial value of 0.06 MPa. The compressive strength of the soil-fiber mixture also increased with time. The corresponding scanning electron microscope results strengthened the findings of this study.
