“…The result of the test indicates that the fiber reduce swell potential and swelling pressure compared with same untreated soil [19]. Babu et al (2008) investigated the effect of coir fiber reinforced black cotton soil and the results showed that the swelling decreases by approximately (40%) with increase fiber from 0.5 to 1.5% and the drop of compression index by about (35%) at fiber content (1.5%) [20]. It can dramatically reduce the excessive settlement of structures built above the soil.…”

Current research main aim is to study the effect of adding polypropylene fiber (PPF) on the behavior of expansive soil to reduce the swelling as percentage (0.5, 1 and 2%) of the weight of dry soil. Expansive soil used in this research was prepared artificially by mixing Ca-based bentonite from geological survey and mining company with sandy soil brought from Karbala city as percentage 80% bentonite to 20% sand of dry weight. Multiple laboratory tests have been carried are (Unconfined Compression Test, One-Dimensional Consolidation Test, Swelling Test, Sieve Analysis and Cycle Swell Shrink Test). A conventional odometer cell was modified to allow the study of swell- shrink cycle test to be carried out under controlled temperatures and surcharge pressure. The results showed that the increase in percentage of (PPF) led to decrease the swelling and to increase the unconfined compression strength. The wetting and drying results of (PPF) showed that with continuous cycles the effect of (PPF) keeps on reducing the swelling and the 2% of (PPF) produces less ratio of swell - shrink, which has obtained higher than 57 % in the improvement factor of swell and shrink.

“…Due to the high lignin content rate of decomposition of coconut coir is less than compared to all other natural fibers. It retains 20% of its strength even after 1 year [19]. These qualities are responsible for use of coconut coir in soil stabilization.…”

Soil which has high shrinkage and swelling property and having poor shear strength has poor stabilization property. Expansive clay soil is characterized by excessive compressive strength, collapse, high swell potential, low bearing capacity, and low shear strength. Such soils are unsuitable for subgrade. These soils are having cracking problems in the dry season and swelling problems in the wet season. By using different techniques, these properties of soil can be improved. The stabilization of soil is one of the important factor used before starting any construction work. In this research paper stabilization of expansive soil is done by using different waste material. The construction of large structures on soils of lesser density becomes a difficult task. The inclusion of some of the industrial waste is one of the soil stabilizing techniques that could be applied successfully to overcome this challenge.

“…Several studies on soil improvement by adding different types, lengths, and percentages of fiber have been carried out. Some authors have studied the effects of fiber on the mechanical behavior of the soil, 3 using synthetic fiber, 4‐6 organic, 7,8 steel fiber, 9 rubber fiber, 10 fiber extracted from palms, 11 and from carpet waste, 12 among other classes. Other researchers have investigated the incorporation of various hazardous materials combined with fibers 13,14 and cement 15,16 .…”

The high content of clay minerals within the soil has a significant effect on its engineering behavior; water affects the interaction of their minerals, which influences their plasticity and deformability. Structures made with or on plastic materials can experience problems due to the high deformations presented in soil. Therefore, decreasing the deformability of plastic soils contributes to the stability and serviceability of the structures supported by this kind of soils. This investigation is about the effect of fique fibers contents in the mechanical behavior of a plastic soil based on a kaolinitetype clay. Fique fiber is natural fiber from Colombia. Soil with additions of 0.0 wt%, 0.2 wt%, 0.7 wt%, and 1.0 wt% of fique fibers was fabricated. The goals by adding the fibers are to increase the compressive strength of the soil and to add a green reinforcement to the soil targeting a circular economy solution. Density, optimal water content, and unconfined compression tests were conducted. The microstructure was characterized with scanning electron microscopy and X-ray diffraction. Results showed that fique fibers improved not only the compressive strength by almost three times for sample with 1.0 wt% of fibers with respect to the reference soil without fibers but also the ductility increased.
