  • Can a high molecular nonionic polyacrylamide (PAM) be used as anti-washout admixtures?
  • In this article, underwater cement paste (UWP) was fabricated through using the high molecular nonionic polyacrylamide (PAM) as anti-washout admixtures (AWAs). The traditional coaxial rotary method was used to systematically investigate UWPs rheology parameters.
  • Why is nonionic polyacrylamide used as anti-scouring admixture?
  • Nonionic polyacrylamide was selected as anti-scouring admixture to eliminate the influence of different polymer electrical properties (Lu et al. 2025 ). The molecular weight of PAM is more than 10 million Daltons, and its main chain is connected with a C=O bond and an amino functional group as a branch chain structure, as shown in Fig. 2.
  • What is polyacrylamide (PAM) used for?
  • npj Clean Water 1, Article number: 17 ( 2018 ) Cite this article High molecular weight (10 6 –3 × 10 7 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
  • What is cationic polyacrylamide (C-PAM)?
  • Cationic polyacrylamide (C-PAM), copolymerized from acrylamide and substituted acrylate or acrylamide segments, offers an alternative to PHPA and exhibits high stability under high TDS conditions 28.
