Abstract
Most of the natural soils and industrial wastes have been identified as problematic geomaterials. Utilization of them for any infrastructural applications have a detrimental effect in the long term. Among the significant problem’s the remediation of erosion and fugitive dust of geomaterials not received much attention from previous studies. The erosion and fugitive dust issues are mainly caused by smaller particles, type of minerals present, temperature, water content, thixotropy, the concentration of ions, type of pore fluid. The general practice is the amendment of traditional stabilizers such as cement and lime. However, these materials are not sustainable, that lead to an increased focus on eco-friendly additives for improving the properties of geomaterials. Synthetic polymers and biopolymers have been identified as viable stabilizers for improving soil properties, erosion control, and prevention of infiltration. However, the durability of biopolymers as stabilizers are of great concern. In this study, an attempt was made to review the use of polyacrylamide (PAM) a synthetic polymerfor mitigating the erosion and fugitive dust issues of geomaterials. This review shows that PAM is promising for the alleviation of erosion and dusting issues. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
