“…(YASMINE and ZEINEDDINE, 2022) They indicated that 1% of polypropylene fibres (12mm and 18mm) mixed with cement content (0, 3, and 6%) and sand through the consolidated drained triaxial test increased both the cohesion and friction angle of sands. A study by (CORREIA and ROCHA, 2021) showed the effects of recycled polypropylene (R-PP) fibres on compacted clayey lateritic soil at different compaction degrees. The results of tests indicated that using fibres improved the shear stress-strain behaviour of the composites and soils compacted at different degrees of compaction.…”

The increase in urbanization has led governments to build on sites with certain geotechnical ‎hazards, such as liquefaction, ‎low bearing capacity, etc. In recent decades, as governments ‎have focused their efforts on the environmental and ‎economic aspects, researchers have ‎emphasized the need to use suitable alternative materials for the best design features, also the issue of plastic pollution is a significant global problem that requires urgent attention, current initiatives focus on the use of technical solutions to integrate non-biodegradable plastics into ‎the construction of buildings and road pavement.‎ ‎In this ‎paper, a series of direct shear tests were performed to evaluate the benefits of plastic wastes, ‎such as polypropylene ‎‎(PP) pots, and the engineering properties of sand reinforced with such ‎materials. To highlight the contribution of the ‎reinforcement to the shear strength, the ‎tests were carried out on sand reinforced with variable fibre contents (0.2, 0.4, 0.6, ‎and 0.8%) ‎for loose-density sand and medium-density sand. ‎ The experimental results showed that the increase in shear ‎strength is relatively more significant for specimens prepared with dry deposition mode as compared to those prepared ‎with wet deposition mode and it is increased with the fibre content. The inclusion of randomly distributed fibres has a significant effect on the shear strength and dilatation of sandy soils. Furthermore, the recycling fibre used in this study ‎shows a better performance in terms of shear strength. In conclusion, the use of plastic waste as ‎reinforcement would lead ‎to at least two solutions: soil reinforcement and reducing the ‎environmental impact of waste.

Expansive clay with great swelling potential requires improvement or stabilization of the soil. It can be successfully done by mechanical and chemical stabilization techniques. This study aims to determine the effect of adding Polyamide (PA) fibre as the material for mechanical stabilization and nano SiO2 as the material for chemical stabilization. The expansive clay used in this study deployed a sample of clay containing mineral montmorillonite with the USCS classification in the high plasticity (CH) category. The mixed materials used include PA fibre with variations of 0.5%, 0.75% and 1% by weight of dry soil and nano SiO2 with variations of 1%, 2% and 3% by dry soil weight. To prove the effectiveness of using nano SiO2, this study compares the treatment with the use of micro SiO2 materials under the same comparison variations. This result indicates that the expansive clay that has been stabilized using PA fibre and nano SiO2 is capable of preventing the swelling potential.
