Abstract: (1590 Views)
In recent years, the use of environmentally friendly microorganisms and biopolymers in geotechnical activities, especially in soil improvement, has received much attention. This is in order to reduce the harmful environmental effects caused by the use of traditional and industrial materials, including cement. Therefore, it seems to be necessary to study the effects of environmentally friendly biopolymers from different points of view, including environmental issues, soil erosion and the factors that influence the geotechnical parameters of the different deposits. The purpose of this article is to review the studies carried out on the use of guar gum. As a green additive from an environmental point of view and the factors that influence the mechanical parameters of soils treated with this biopolymer. The advantages and disadvantages of guar gum from an environmental point of view, as well as the effects of this additive on different soils, are the subject of discussion. Geotechnical parameters such as the unconfined compressive strength, the shear strength, the erosion resistance and the durability of the soils treated with guar gum will be evaluated. The influence of the guar gum parameters in relation to the concentration of the biopolymer guar gum, the moisture conditions, the temperature and the processing time will then be discussed. Finally, the potential opportunities and challenges for the use of guar gum in the geotechnical field will be presented.
