Popis: Soft soil suffered from different aspects for example high compressibility and low shear strength; in which cannot provide satisfactory support to any structure. In order to support such type of soil, the synthetic/natural fiber reinforcement has been recently suggested to ensure the stability of buildings and infrastructures. This technique involves the randomly mixing of soil with small discrete materials like fibers or meshes to get a homogeneous material. The Kaolin (K) and jute fiber (JF) were used to prepare unreinforced and reinforced specimens for the experimental work. The JF was chosen as a reinforcement material with different contents namely (0.5%, 1%, 2%, and 3%). The fibers were cut into two different lengths (2 cm and 4 cm). A total of 27 laboratory tests including standard Proctor compaction test, one dimensional consolidation test, and unconfined compression test were conducted on the prepared mixture to investigate the effect of jute fibers on the behavior of clay. The maximum dry density decreases and optimum moisture content increases with the inclusion of JF. Mixing the clay with JF of 0.5% decreases the maximum dry density MDD by 5% less than the unreinforced clay. The JF greatly influenced the unconfined compressive strength (UCS) for all that fiber’s content and length. UCS of the JF specimen is 4.26 times that for the natural clay. Moreover, JF increases the failure strain especially for fiber length L= 4 cm. The reinforced clay specimens show almost a strain softening behavior.
