  • Does polyacrylamide mix with silty soil?
  • The geotechnical properties of Polyacrylamide (PAM) mixed with a type of local soil called silty soil are discussed in this study. First, five mixed variations of PAM (0.2%, 0.4%, 0.6%, 0.8%, and 1%) were tested in the laboratory to determine local soil properties.
  • Does water soluble polyacrylamide change physical and mechanical properties?
  • This laboratory study uses a sustainable water-soluble polyacrylamide (PAM) as an additive to determine the potential changes to physical and mechanical properties. This study is centred on the mechanical properties of cohesive soils. Furthermore, the experiments are supported by observing the morphology of soils at particle content.
  • Does adding anionic polyacrylamide improve soil aggregation?
  • Adding anionic polyacrylamide (PAM) to soils stabilizes existing aggregates and improves bonding between and aggregation of soil particles. However, the dependence of PAM efficacy as an aggregate stabilizing agent with soils having different clay mineralogy has not been studied.
  • Does acrylamide bond increase soil strength?
  • The results from the analysis of particle content show that PAM mainly interacts with soil particles. That confirmed the pores space had been reduced by acrylamide bonds that can increase soil strength. In the bearing capacity, a dosage of 0.4% PAM is the minimum to fill up the requirements for backfill materials.
