Interface Resistance between Clays and Natural Hemp Fibers
The interface shear strength is essential for the design and safety assessment of deep foundations, offshore and onshore pipelines, mechanically stabilized earth walls, and fiber-reinforced soils, among others. Despite the wealth of data on the interface shear resistance between soils and solid interfaces, there is limited information on the interface resistance between clays and natural fibers, which are currently being considered as a sustainable measure of soil improvement. In this study, a comprehensive experimental program is implemented to investigate the interface shear strength between a sandy clay and natural hemp fibers. It consisted of a series of direct shear tests conducted on both clay-clay and clay-hemp interfaces, in addition to another series of single fiber pullout tests at different rates of loading. Clay samples were compacted at optimum water content and maximum dry density. Results indicate that the interface shear strength parameters that characterize the fiber/soil interaction are significantly affected by the test mechanism and the rate of loading.
