Shear strength properties of wet granular materials [PDF]
Physical Review E, 2006 We investigate shear strength properties of wet granular materials in the pendular state (i.e. the state where the liquid phase is discontinuous) as a function of water content. Sand and glass beads were wetted and tested in a direct shear cell and under

Switching off PAE wet strength [PDF]
Nordic Pulp and Paper Research Journal, 2019 Abstract The wet strength of cellulose-cellulose joints, reinforced with PAE-loaded microgels, was decreased by nearly a factor of two when the labile disulfide crosslinks on the supporting microgels were exposed to a reducing agent. The supporting microgels were temperature and pH sensitive poly(N-isopropylmethacrylamide-co-acrylic acid)
