- Abstract
The article by Ghasemi et al. discusses the mechanical behavior of sand mixed with Polyurethane foam. The authors found that incorporating Polyurethane foam into sand significantly improved the shear strength parameters, particularly cohesion. However, the authors did not investigate the impact of Polyurethane foam on the strength-dilatancy relationship of the sand, which is an important aspect of soil behavior. They also did not mention the use of the Bolton stress-dilatancy equation to assess the stress-dilatancy behavior of the sand-foam mixtures. Further research is encouraged to explore the potential of using Polyurethane foam as a stabilized material for coarse-grained soils and to investigate other factors such as curing time and compaction effort on the mechanical behavior of the stabilized soil.
