Slit Pores

Humidity-dependent closing and reopening slit pores can produce hysteresis loops in sorption diagrams even at low relative vapor pressure. Pore closing is supported by adhesion of the slit wall surfaces. In a macroscopic model for sorption hysteresis in narrow slits, the adhesion energy jumps by a finite value when touching slit walls are separated from each other. We consider a more realistic adhesion model by introducing a smoothly-varying adhesion force, which depends on the distance between the slit walls. The range of the attraction between the slit walls is found to have a pronounced influence on the shape of hysteresis loops at low vapor pressure. A large interaction range avoids an extraordinarily small relative vapor pressure necessary for pore closing, which is a precondition for low pressure hysteresis. Our extended model allows us to describe a discontinuity, which can appear in the desorption branch of swelling/shrinkage diagrams for hardened cement paste.

Different Origin

Abstract Some recent experiments on the diminution of the vapor pressure of solvents in rubber jellies, as well as measurements of swelling pressure, allow us to draw some conclusions as to the nature of the swelling phenomenon. It has been found that, at the same concentration of rubber, the vapor pressure of rubber jellies from rubber of different origin was the same, and the previous mechanical working (mastication) of rubber had also no effect on this value (cf. Stamberger, Rec. trav. chim., 47, 316 (1928)). After the mechanical working, however, it swells in an unlimited manner, and gives as a resulting product up to a concentration of 30 per cent a more or less viscous liquid. This behavior shows that the solvent is not bound by surface adsorption and that there is a great resemblance to the process of molecular disperse solution. The three solvents used for these determinations were carbon disulfide, chloroform, and benzene. The same relative vapor pressure diminution was found when the concentration has been calculated as grams of rubber in 1 gram-molecule of solvent.
