The Pressure induced by salt crystallization in confinement
Salt crystallization is a major cause of weathering of rocks, artworks and monuments. Damage can only occur if crystals continue to grow in confinement, i.e. within the pore space of these materials, thus generating mechanical stress. We report the direct measurement, at the microscale, of the force exerted by growing alkali halide salt crystals while visualizing their spontaneous nucleation an...
متن کاملFracture of Porous Materials Induced by Crystallization of Salt
The penetration of salt into porous materials is known to have deleterious effects, often resulting in fracture. The damage process begins with a saline solution penetrating the porous network by way of capillary action. This is followed by supersaturation of the saline solution, which may result in the formation of salt crystals. In turn, these salt crystals induce pressure on the pore walls. ...
متن کاملSalt crystallization in porous construction materials I Estimation of crystallization pressure
The crystallization process of soluble salts inside the natural and artificial porous materials partially immersed in different saline solutions has been studied, This procedure is used to simulate the conditions of exposure to salt weathering in which foundations and lower walls of building structures are within the zone of capillary rise of saline
متن کاملIn situ pressure crystallization: an alternative to crystallization by cooling
Acta Crystallographica Section A: Foundations and Advances publishes articles reporting fundamental advances in all areas of crystallography in the broadest sense. This includes metacrystals such as photonic or phononic crystals, i.e. structures on the mesoor macroscale that can be studied with crystallographic methods. The central themes are, on the one hand, experimental and theoretical studi...
متن کاملChronology of blood pressure changes in renal hypertension induced by solid plexiglass clips in the rat
The objective of this study was to determine the chronology of changes in blood pressure in renalhypertension induced by solid plexiglass clips in rats. Saw blades with the thickness of 0.21-0.22 mm wereused to make clips sized 4 × 2 × 2 mm from a piece of 2-mm thick plexiglass. Rats were subjected to shamoperation or left renal arterial clipping, and 1, 2, 3 and 4 weeks later blood pressure, a...
