摘要本文综述了无机多孔材料的盐致劣化，重点讨论了与理解这一现象最相关的问题。这些是水/水分和盐在孔隙系统内的运动;盐的存在对水分吸收的影响;一种以上盐的同时存在的影响;盐在砌体中的分布;劣化机制;和风化模式。在后者中，最普遍的是粉化和剥落，并且已发现它们发生在大多数石头类型上。然而，在不同的石头上诱导相同外观的机制可以根据多孔材料，盐和水分之间的协同作用而显着变化。
Abstract The present overview on salt-induced deterioration of inorganic porous materials focuses on those topics considered the most relevant for understanding this phenomenon. These are movement of both water/moisture and salts within the pore system; influence of the presence of salts in moisture absorption; effect of the simultaneous presence of more than one salt; salt distribution in masonry; deterioration mechanisms; and weathering patterns. Of the latter, the most ubiquitous are powdering and scaling, and they have been found to occur on most stone types. However, the mechanism that induces the same outward appearance on different stones can vary significantly depending on the synergism that develops among porous material, salt, and moisture.
