“…The soil used was mined in and around the Chlef river Chlef province, Algeria. Many studies were conducted on this soil and its physical and mechanical properties have been examined by numerous researchers (Adda Berkane et al, 2022;Bouri, Krim, Brahimi, & Arab, 2019;Della, Muhammed, Canou, & Dupla, 2016;Denine et al, 2021). The maximum void ratio (emax) corresponding to the loosest state of the soil sample and minimum void ratio (emin) corresponding to the densest state of the soil sample were determined according to ASTM D4253 (ASTM, 2006a) and ASTM D4254 (ASTM, 2006b) standards.…”

Incorporating fibers into the soil is a reinforcement remediation technique to improve its physical and mechanical properties. Depending on the type of fibers, synthetic fibers, have negative impacts on the environment linked to the waste of their chemical industry. Currently, vegetal fibers consider an economic and ecological alternative to soil reinforcement. Therefore, this study aims to evaluate the influence of two types of randomly distributed fibers (Alfa and Sisal fibers) on the mechanical properties of sandy soil. Direct shear tests were performed on Chlef sand at relative density (Dr = 75% and 40%) and of fiber contents varying from 1, 2, 3 and 4% for sand samples reinforced with Alfa fibers and 0.1, 0.3, 0.5 and 0.7% for sand samples reinforced with Sisal fibers. The test results show that the inclusion of vegetal fibers in sandy soil improves the peak and residual shear strength. In addition, soil resistance was found to attain a maximum with the optimums of 0.7% for sisal fiber content and 3% for Alfa fibers.

“…Biopolymer xanthan gum can significantly improve the shear strength and unconfined compressive strength of soil through agglomeration and adsorption, while reducing the collapsible potential of soil [7,8]; β-1,3/1,6-glucan biopolymer greatly improves the compressive strength of soil by forming ionic bonds with clay particles [9]. Biopolymers show impressive strength in improving soil engineering properties [10][11][12]. However, the biopolymer reinforced soil commonly exhibit brittle behavior [13,14].…”

Due to environmental concerns, the search for eco-friendly and efficient soil reinforcement has become urgent in recent. In this paper, the low-carbon and environment-friendly materials biopolymer and fibers were used for soil reinforcement. Direct shear tests were carried out to determine the reinforcement effect, results show that the shear strength of soil increases first and then decreases with the increase of fiber content, it reaches to the peak value at the content of 0.5%. Biopolymer increases soil shear stregnth and 0.5% content presents most effective strengthening effect. When biopolymer and fibers are mixed into soil, it show better reinforced effect than the sum of individual efforts.
