“…In the field of soft soil stabilisation, POFA has been used as a cement replacement in order to improve the Atterberg limits and unconfined compressive strength (UCS) (Pourakbar et al, 2015). Ground POFA was used in two different particle sizes (30µm and 12µm) by Mujah et al (2015) for soil improvement. Shear and one dimensional consolidation tests were conducted to evaluate the effect of different sizes of POFA particles in soil stabilisation, the results indicating that fine grade POFA gave a much more pronounced improvement in comparison to the coarse grade.…”

Soil stabilisation using traditional binders such as Ordinary Portland Cement (OPC), has a serious negative environmental impact, specifically carbon dioxide (CO 2) emissions as a result of the manufacture of OPC. Because of this, the use of sustainable binders has become a critical issue to help reduce cement production through the use of by-product materials. This research seeks to develop a new ternary blended cementitious binder (TBCB) to replace cement for soft soil stabilisation. Different ternary mixtures containing wastes i.e., high calcium fly ash (HCFA), palm oil fuel ash (POFA) and rice husk ash (RHA) along with flue gas desulphurisation (FGD) gypsum used as a sulphate activator and grinding agent, were examined. The results illustrate that ternary mixtures improved the engineering and mechanical properties of stabilised soil. The results indicated that the plasticity index (PI) was reduced ACCEPTED MANUSCRIPT from 20.2 to 13.0 and the unconfined compressive strength (UCS) increased after 28 days of curing from 202kPa to 944kPa using the optimum non-FGD activated mixture. FGD contributed significantly by increasing the UCS to 1464kPa at 180 days of curing, which surpassed that for the reference cement (1450kPa), and by improving the soil consistency limits; where the PI decreased to 11.7 using TBCB compared with 14.5 for the soil treated with the reference cement. X-ray diffraction (XRD) and scanning electron microscopy (SEM) analysis revealed substantial changes in the diffraction patterns and microstructure components of the TBCB paste over the curing period, confirming the formation of cementitious products. A solid, coherent and compacted structure was achieved after treatment with TBCB as evidenced by the formation of C-S-H, CH and ettringite.

“…The amount of natural fiber incorporated into the soil is a variable that can compromise its benefits as a reinforcement. [41,42,43] concluded that the best experimental yield was found for samples incorporating a higher content of smaller length fibers. The compressive, shear, and tensile strength tend to decrease with excessive fiber content.…”

Improvement of the soil's properties in order to resist erosion is desirable, and soil reinforcement is one of the techniques used to achieve this. The incorporation of natural fibers into the soil to form a composite material has been widely investigated. The most common natural fibers used for soil reinforcement are green coconut, sisal, and jute fibers, which were the subject of the systematic review carried out in this study. The study also presented babassu coconut as a potential material for soil reinforcement. Using the methodology adopted, 76 publications related to the theme were selected and studied. This study made use of the Periodicals Portal virtual library and the articles selected were limited to peer-reviewed articles published between 2008 and 2019 in either Portuguese or English. The references of the selected articles were also analyzed. The data from the selected publications were analyzed and described under the following discussion topics: natural fibers in soil reinforcement (green coconut, sisal and jute), ideal fiber length and content for soil reinforcement, correlation between fiber content and ideal length, aspects of babassu, and future perspectives for the use of babassu. It was concluded that the natural fibers increase the mechanical properties of the soil and that the babassu husk fiber also has potential to improve the soil. It is necessary to investigate, among other characteristics, the ideal fiber length and content for the principal types of soil found in the northeast region, as well as to evaluate the effect of saturation and durability over time. I. INTRODUCTIONConcern over soil erosion has reached a high level of importance in many regions of the world, due to the loss of considerable amounts of arable land, the silting up of water bodies, and the occurrence of landslides [1,2]. The form soil erosion takes may vary according to local climatic conditions. For example, tropical and semi-arid regions of Michele Joyce Pereira dos Santos et al.
