“…Tuffs may show highly differential behavior and resistance to salt crystallization processes, often depending on their mineralogy, pore radii distribution and expansional behavior (Çelik and Sert 2020;Germinario and Török 2019;López-Doncel et al 2016;Pötzl et al 2018aPötzl et al , b, 2021aYu and Oguchi 2010). Comprehensive data on the salt weathering of 17 volcanic tuffs from Mexico can be found in López-Doncel et al (2016).…”

Many cultural heritage sites in Mexico have been built with volcanic tuff rocks from the earliest Central American civilizations to the time of the Spanish conquest and up to the present. Throughout this long period of time, the stones have been subjected to progressive weathering as evidenced by different types of damage phenomenon such as scaling, sanding, crumbling, sugaring and salt efflorescence. This study utilizes a collection of 53 tuffs from different regions in Mexico that show a diverse range of colors, rock compositions and mineralogy, and heterogeneous rock fabrics indicative of their volcanic origin. Comprehensive investigations have been done that include detailed petrographic analyses, cathodoluminescence, clay mineral analyses, and the determination of a wide range of petrophysical properties (e.g., porosity, capillary water uptake, water absorption, sorption, hydric and thermal expansion, and mechanical properties). All analyzed data combined are used for derivation of some general trends concerning the suitability/durability of tuffs applied as natural building stones.

“…Presently, studies have been carried out using experimental laboratory simulations to assess stone durability produced by freeze-thaw test, thermal shock weathering and salt crystallization [19,20]. The modification in pore size distribution is an important parameter, because it determines limestone durability to ice and salt crystallization cycles [21], and an increased crystallization pressure [22].…”

This paper aims with the preparation of Sr2+ and Zn2+ double substituted carbonated hydroxyapatite (Sr-Zn-CHAp) by the nanoemulsion method and to evaluate its consolidation capacity on artificial stone samples. The changes in CHAp lattice parameters were observed by a synergy between the shrinkage and dilatation induced by the two metallic ions, with different ionic radii by comparison with calcium. The changed morphology obtained by calcination was evidenced by SEM analysis. Also, the tendency to agglomerate of the double substituted CHAp as micron- and sub-micron-sized particles with spherical and irregular form was observed. The FTIR, XRD and EDS results confirmed that the CHAp was successfully substituted with Sr2+ and Zn2+ by replacing Ca2+ resulting a AB-type CHAp. The efficacity of Sr-Zn-CHAp as inorganic consolidant for the stone was tested by mechanical strength, resistance at freeze–thaw artificial aging test, thermal shock weathering, colorimetric changes of the artificial stone sample, all the results being correlated with the water absorption test, water repellency, and pore structure changes. By treating the stone with 0.5 g/L Sr-Zn-CHAp led to an improvement of the above-mentioned characteristics, without significant chromatic changes.

“…Magnesium sulfate and its hydrate are common salts that cause pathological changes in porous materials. The crystallization behavior of the salt solution in the pores of the materials leads to the formation and expansion of cracks, and the main destructive forces include crystallization force and hydraulic force. − Previous research on magnesium sulfate mainly focused on how it affected and destroyed contemporary silicate materials like cement and concrete. − With regard to the precipitation of magnesium sulfate whiskers on the surface of porous materials, Zhang once found magnesium sulfate whiskers on the soil of the Lidu wine-brewing workshop site in Jiangxi Province, China. He speculated that magnesium ions and sulfate ions were mainly derived from the wine-making process; Liu believed that the needle-like magnesium sulfate whiskers grown on the surface of the ceramic cricket boxes collected in the Hunan Museum of China were related to the high local relative humidity, and their ionic components came from impurities in the raw materials .…”

The wooden sluice site of the Nanyue Kingdom in Guangzhou, China, is covered with white magnesium sulfate salt whiskers continuously growing from the surface. In this paper, polarizing microscopy, scanning electron microscopy, infrared thermography, Fourier transform infrared spectrometry, and surface tension analysis were utilized to comprehensively analyze the micromorphology of whiskers grown on the surfaces of porous materials collected at the site of Nanyue Kingdom, as well as the change laws of magnesium sulfate solution droplets on the porous hydrophilic matrix, and the migration and crystallization of magnesium sulfate solution in the capillary tube. The diameters of magnesium sulfate salt whiskers grown on the surfaces of porous samples range from 30 to 110 μm. For the first time, it is clear to see that the whisker’s structure is hollow and nodular. There are solid crystalline salts in hollow tubes, and some of them are aqueous. The top sections of whiskers are approximately circular and are composed of particles with a size of about 0.4–4.0 μm. Their growth conditions are mainly characterized by the high humidity environment where the porous material is located or locally located, the formation of an annular whisker base, and the pressure difference generated during the formation progress of water-bearing crystals in the capillary of the whisker. The research results expound on the circumstances and mechanism of magnesium sulfate solution-induced whisker development on the surface of porous materials, providing a reference for the study of the whisker growth mechanism.
