Cristallizzazione del solfato di sodio in calcari biomicritici: l'uso di inibitori per la mitigazione del degrado
Salt crystallisation is one of the most harmful decay problems in porous materials. Especially ancient building and archaeological sites can show very intense damage (e.g. detachment and pulverization of the materials) that produce a strong loss of matter and so cultural identity. Mainly hypogea …

Factors influencing salt-induced weathering of building sandstone.
The role of chemical cleaning in causing salt-induced weathering of building sandstone was investigated by looking at the changes in a series of weathering indicators selected. These were mainly, porosity and pore size distribution changes, chemical composition and colour changes. Laboratory …

An experimental method to measure crystal growth rate in porous materials and quantity deformation developed during crystal growth
… method to quantify dam-ages produced by salt crystallisation in porous building materials, a phenomenon long considered as one of the most important cause of deterioration problems, occurring in monuments exposed to a wide range of environmental conditions [125]. Sodium sulphate in …
