“…Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and thermogravimetry (TGA) analysis results suggested that all amino acids displayed the ability of calcite inhibition and amorphous calcium carbonate (ACC) facilitation, but to different degrees. It is intriguing to note that the effect revealed by a single amino acid can be similar to that of whole proteins, since in our previous studies on lime-based mortars with oxblood addition, the formation of ACC in mortars with oxblood addition was also confirmed by FTIR, XRD, TG-DSC and SEM analyses [12,51,52]. It was speculated in these previous studies that ACC stabilization could be realized through lowered supersaturation in solution by combination between calcium ions and protein sections rich in glutamic acid, serine, glycine, and carbohydrates.…”

The addition of protein-based additives (e.g. milk, egg white, animal blood) into lime mortars can improve mortar properties such as workability, strengths and durability. With the intent to understand how and why proteinaceous additives improve lime mortar properties, it could be useful to start from the basic building blocks of proteins amino acids. Consequently, the present study focuses on the influence of polar amino acids on the carbonation of lime mortars, and the results demonstrated that addition of amino acids into mortars could slow down mortar drying, increase surface hardness, slow down carbonation, promote amorphous calcium carbonate stabilization and inhibit calcite formation; moreover, these effects seemed to become more evident with the increase of amino acid concentration. It was speculated that in highly alkaline lime mortars, polar amino acids could lime carbonation by interacting with calcium carbonate via H-bonds and additional Ca2+ mediated adsorption.

“…The specific peaks at around 1083, 855 and 702 cm −1 found in all the samples suggest the presence of calcium carbonate in the mineralogical form of aragonite, both in the support and mixed with the pigments. The 855 and 702 cm −1 signals are due to ν2 and ν4 CO3 2− vibrations, respectively, and the absorbance at 1083 cm −1 could be attributed to ν1 symmetric CO3 2− stretching [13,14]. Figure 4a shows a representative spectrum of aragonite, identified in sample ST6, where the peaks are clearly distinguished from those of calcite.…”

Unexpected Findings in 16th Century Wall Paintings: Identification of Aragonite and Unusual Pigments

Sixteenth century wall paintings were analyzed from a church in an advanced state of decay in the Apennines of central Italy, now a remote area but once located along the salt routes from the Po Valley to the Ligurian Sea. Infrared spectroscopy (FTIR-ATR), X-ray diffraction (XRD) and scanning electron microscopy (SEM) with a microprobe were used to identify the painting materials, as input for possible future restoration. Together with the pigments traditionally used for wall painting, such as ochre, ultramarine blue, bianco di Sangiovanni, cinnabar/vermilion, azurite, some colors were also found to have only been used since the 18th century. This thus suggests that a series of decorative cycles occurred after the church was built, confirmed by the multilayer stratigraphy of the fragments. Some of these colors were also unusual, such as clinochlore, Brunswick green, and ultramarine yellow. The most notable result of the analytical campaign however, was the ubiquitous determination of aragonite, the mineralogical form of calcium carbonate, mainly of biogenic origin. Sources report its use in Roman times as an aggregate in mortars, and in the literature it has only been shown in Roman wall paintings. Its use in 16th century wall paintings is thus surprising.

“…The earliest organic–inorganic composite building mortar was discovered in China and dates to 2300 BCE [ 9 ]. It has been shown that ancient traditional lime-based binders contained organic additives such as glutinous rice [ 10 , 11 , 12 , 13 ], tung oil [ 7 , 14 , 15 ], blood [ 16 , 17 , 18 , 19 ], egg white [ 20 , 21 ], sugar [ 20 ], gelatin [ 6 , 9 ], and peach gum [ 2 ]. Similarly, these lime-based mortars also emerged in other countries around the world.…”

“…In Myanmar, glutinous rice and proteins were added to building mortars to meet higher living requirements [ 6 ]. From reports in the literature such as glutinous rice–lime mortar [ 11 , 24 , 25 , 26 , 27 ], tung oil–lime mortar [ 27 , 28 , 29 ], blood–lime mortar [ 17 , 18 , 19 ], egg white–lime mortar [ 20 , 21 , 28 ], and sugar–lime mortar [ 20 , 28 ], the same conclusion that organic–inorganic composite mortars have strong adhesion properties could be drawn. In these natural organic matters, blood–lime mortar has received special attention.…”

“…After curing, proteins accumulated on the surface, forming a smooth and dense protective layer that enhanced the material’s waterproofing and weather resistance. Zhang et al [ 19 ] investigated the impact of ox blood on lime-based mortars through TG and ATR. In the early stages of curing, ox blood promoted the formation of amorphous calcium carbonate, which, over time, could transform into vaterite and then calcite.…”

In the ancient Chinese recipe for composite mortar used in the construction of ground layers for architectural painting, the mixture of porcine blood and lime water is one of the constituent materials. Herein, according to the traditional recipe, the interaction between porcine blood and lime water was systematically and deeply investigated. The experimental investigation demonstrated that porcine blood mixed with lime water at the ratio found in the recipe can form a hydrogel with a hydrophobic surface. During air-drying, the lime water in porcine blood hydrogel can react with CO2 to form calcium carbonate. The crystal morphology of the formed calcium carbonate depends on the surrounding micro-environment of calcium ions in the porcine blood hydrogel. The formed morphology of calcium carbonate includes small calcite crystallites, small graininess calcite crystals with round features, calcite aggregates with layered ladder-like structures, and amorphous calcium carbonate (ACC). Interestingly, the calcium carbonate formed in the inner part of the porcine blood hydrogel exhibits lamellar distribution due to a Liesegang pattern formation. Based on the findings that the porcine blood hydrogel has surface hydrophobicity and brittleness, it can be predicted that in the preparation process of composite mortar for ancient building color painting base course, porcine blood used in the form of a hydrogel is not only easier to be dispersed in hydrophobic tung oil than in liquid porcine blood but also the affinity between porcine blood gel and tung oil is enhanced. As constituent material dispersed in the composite mortar, the layered distribution of calcium carbonate in the porcine blood hydrogel may presumably be beneficial to reduce the internal stress of the composite mortar material.
