“…According to the surface morphology shown in Figure 8, there were large cracks on the surface of sample A, which were beneficial to the exchange of water vapor inside and outside. This had a small impact on gas permeability [32], consistent with water absorption test results. The surface of sample V was uniform and dense, which may have hindered the exchange of water vapor and had a greater impact on the air permeability.…”

The purpose of this work was to use different surfactants to deposit different crystalline calcium carbonate films on the surface of sandstone through a simple double displacement reaction. This was done to test the protective effects of calcium carbonate coatings based on water absorption, moisture permeability and weather resistance. Experimental results showed that the air permeability of the stone treated with vaterite calcium carbonate was reduced, but that this did not affect water vapor’s access into and out of the stone. Compared with untreated stone, the water absorption rate was reduced 0.5 times, and the weather resistance increased by 4 times due to small crystal grains, high solubility, and deep penetration hindering the erosion of water and soluble salts. These findings are expected to provide useful suggestions for the protection of stone cultural heritage.

“…After our treatment, the contact angle of the sandstone sample surface decreased, and the hydrophilicity increased. There are two reasons for the decrease in the contact angle of the sandstone surface: the rst is that the calcium carbonate particles are on the sandstone surface, increasing the surface roughness of the hydrophilic stone and improving the surface hydrophilicity; the second is that calcium carbonate deposited on the surface of sandstone produces a large number of hydrophilic hydroxyl groups in the aqueous solution, which is easy to attract water molecules [22].…”

The purpose of this work is to use different surfactants to deposit different crystal forms of calcium carbonate film on the surface of sandstone through a simple double replacement reaction. The protective effect of calcium carbonate coatings was evaluated through water absorption, water vapor permeability and weather resistance tests. The results show that the stone treated with vaterite calcium carbonate has excellent water absorption and permeability. Compared with untreated stone, the water absorption rate is reduced by 0.5 times, and the weather resistance is increased by 4 times, effectively hindering the erosion of water and soluble salts. These findings are expected to provide useful suggestions for the protection of stone cultural heritage.

“…AFM force measurements in a dissimilar surface configuration with one calcite surface against a smooth and less-reactive surface (such as colloidal silica, gold, or substrates with modified hydrophilicity) are less experimentally challenging and provide a higher distance resolution. − These works point to the dominant effect of ion-specific hydration on the repulsive forces measured at the smallest surface separations and show a significant decrease of the measured adhesion in the presence of Ca 2+ . The strong ion-specific effects on adhesion between calcite and a functionalized AFM tip have also been demonstrated in a molecular dynamics study for several different crystallographic planes of calcite .…”

Solution composition-sensitive disjoining pressure acting between the mineral surfaces in fluid-filled granular rocks and materials controls their cohesion, facilitates the transport of dissolved species, and may sustain volume-expanding reactions leading to fracturing or pore sealing. Although calcite is one of the most abundant minerals in the Earth’s crust, there is still no complete understanding of how the most common inorganic ions affect the disjoining pressure (and thus the attractive or repulsive forces) operating between calcite surfaces. In this atomic force microscopy study, we measured adhesion acting between two cleaved (104) calcite surfaces in solutions containing low and high concentrations of Ca 2+ ions. We detected only low adhesion between calcite surfaces, which was weakly modulated by the varying Ca 2+ concentration. Our results show that the more hydrated calcium ions decrease the adhesion between calcite surfaces with respect to monovalent Na + at a given ionic strength, and thus Ca 2+ can sustain relatively thick water films between contacting calcite grains even at high overburden pressures. These findings suggest a possible loss of cohesion and continued progress of reaction-induced fracturing for weakly charged minerals in the presence of strongly hydrated ionic species.
