2024年11月1日 · Reliable simulation of salt crystallization risk and its effects on masonry requires the development of Multiphysics (hydro-thermo-chemo-mechanical) models that accurately represent the physical and transport properties (e.g., porosity, pore size distributions, moisture capacity, moisture and ion permeability/diffusivity, thermal conductivity ...
Salt Crystallisation in Masonry - Building Conservation
While salt crystallisation in porous building materials has long been seen as an important cause of deterioration problems, much remains to be understood about how it works, why it causes damage and how best to prevent and treat salt problems. This article reviews the current state of scientific understanding on the problem and potential solutions.
Effectiveness of crystallization inhibitors in preventing salt …
2007年7月1日 · Salt crystallization in porous materials constitutes one of the most frequent causes of decay of buildings, in a wide range of environments. Pressures created by crystallization of salt in pores weaken the material until its mechanical strength is overcome and damage occurs.
Salt crystallization in porous materials : an NMR study - Semantic …
Salts are widely recognized as a cause of deterioration of porous building materials. One of the proposed mechanisms for salt weathering is crystallization pressure. Salt crystals in pores are under pressure because of their own surface energy.
Salt crystallization as damage mechanism in porous building …
Salts can damage building materials by chemical reactions or crystallization, which is a serious threat to cultural heritage. In order to develop better conservation techniques, more knowledge of the crystallization processes is needed. In a porous material, the size of a salt crystal is limited by the sizes of the pores.
