Crystal growth in salt efflorescence
WebIf the efflorescence is essentially uniform throughout the exterior facade, it indicates normal water loss from the materials and the building. Some identify this occurrence as “early age” efflorescence or “new building bloom”. If unattended, the salts will eventually be removed by rain water. If the deposit is heavy and essentially ...

WebJan 15, 2015 · In case of the salt mixture, at the maximum concentration of inhibitor (0.01 m) a supersaturation of 1.16 is observed compared to 1.55 in case of the single salt. One of the reasons for this relatively low supersaturation can be the fact that ferrocyanide ions act as a growth inhibitor for both NaCl and KCl [15], [26].
WebAqueous inorganic ions are a major component of atmospheric aerosols, typically comprising 25 to 75 percent of the dry aerosol mass. At sufficiently low relative humidity (RH), aqueous inorganic aerosols can undergo crystallization with the loss of particle-phase water (efflorescence), which alters the aerosol’s effect on global climate and many … Webface, this causes the salts to crystallise out, often producing the white crystals known as efflorescence on the surface. While these fluffy white crystals can appear dramatic, they are relatively harmless compared to hidden salt crystallisation (cryptoflorescence) which can occur within the pores below the masonry surface.
