  • Which cationic polyacrylamide has a charge density of 40%?
  • Three commercial cationic (PAM +S,τ40 ), nonionic (PAM °S) and anionic (PAM −S,τ40) polyacrylamides (PAMs) with a medium chain length produced by the SNF group (Andrézieux, France) were used ( Table 1 ). PAM +S,τ40 and PAM −S,τ40 have a charge density of 40%.
  • What is nonionic polyacrylamide?
  • Nonionic polyacrylamides represent the smallest group of acrylamide-based polymers, representing about 25% of the total polyacrylamide market. Nonionic polyacrylamide is somewhat misleading since in the manufacture of acrylamide, regardless of the route, some degree of hydrolysis of acrylamide occurs.
  • 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.
  • 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.
