  • Does polyacrylamide affect aqueous solutions and fresh cement pastes?
  • In this paper, we study the effects of polyacrylamide (PAM) on both aqueous solutions and fresh cement pastes. Our solution viscosity and hydrodynamic radii measurements in various solutions suggest that calcium ions lead to a cross-linking of anionic PAM and to the formation of PAM micro-gels.
  • How does Pam affect the rheological properties of cement pastes?
  • Bessaies-Bey et al. studied the influence of PAM on the rheological properties of fresh cement pastes and found that micro-gel was formed through the complexation between PAM and calcium ions, and thus bridging cement particles.
  • Do polyacrylamide micro-gels bridge cement grains?
  • We measure adsorption isotherms of polyacrylamide on cement grains. We suggest that polyacrylamide micro-gels do bridge cement grains and increase the yield stress of cement pastes. In this paper, we study the effects of polyacrylamide (PAM) on both aqueous solutions and fresh cement pastes.
  • Does polyacrylamide adsorption affect the structural buildup of IPMC paste?
  • This paper also found that the dispersing effect produced by the AM adsorption and the flocculating effect generated from the polyacrylamide (PAM) microgels bridging would jointly impact the structural buildup of IPMC paste; the former improved the rheological properties and fluidity, while the latter acted contrary.
