“…Specifically, nanolime dispersions in a mixture of 50% water and 50% iso-propanol in volume, (W/A = 50%), demonstrated to be particularly suitable in optimizing the carbonation process [14,29].The aim of the present work is to test the effectiveness of this nanolime as a compatible treatment on biocalcarenite stones. Specifically, these stones constitute the building material used for most of the buildings of the "Valley of the Temples" in Agrigento -Sicily, Italy, characterized by a documented advanced decay [32][33][34]. The paper has been divided into three parts:…”

Nanolime is a promising consolidant for the conservation of most historic structures thanks to its high compatibility with carbonate-based substrates. Nanolime can recover the superficial cohesion of deteriorated surfaces thanks to its potential to complete the carbonation process, recreating a thin network of new cementing calcium carbonate. In this paper, the nanolime was produced by an innovative, time and energy-saving and scalable method, and its efficacy was tested preliminarily on biocalcarenite stones from Agrigento. The stones characterization as well as the treatment effectiveness, in terms of protection against water and superficial consolidation, was investigated by several techniques such as X-ray fluorescence, X-ray diffraction, scotch tape test, water absorption by capillarity, mercury intrusion porosimetry, drilling resistance measurement system and colorimeter. Investigations showed that nanolime could guarantee a complete transformation in pure calcite together with a superficial consolidation and a reduction in water absorption.

“…This nding supports that the petrographic analyzes obtained in various studies in the literature provide information about the nature and distribution of the mineralogical phases and elements within the stone sample and the stone interface, which contributes to the identi cation of essential minerals and the behavior responsible for stone degradation. In addition, petrophysical and petrographic properties determine the amount and degree of weathering of stone monuments and support the fact that weathering processes and damage analyzes can be explained by examining these properties in the material [12][13][14][15][16][17][18].…”

Petrophysical and petrographic properties determine the amount and degree of weathering of stone monuments, and weathering processes and damage analyzes can be easily explained by examining these properties in the material [13][14][15][16][17][18]. However, in order to understand the material behavior in detail, it is necessary to conduct an integrated systematic study from different aspects such as examining the in-situ conditions of the building, archaeometric research, investigating the previous phases of the building [19][20].…”

In historical stone structures, material deterioration occurs over time due to climate-related reasons. In order to perform the correct interventions to these material deteriorations in the building, original material properties should be determined and restoration applications should be carried out in accordance with these properties. In this study, it was aimed to examine the material properties and problems of the Mor Yakup Church, in the Nusaybin District of Mardin Province, in order to create a laboratory guideline that reveals the material analysis to be used in the restorations to be made at the regional scale of Mardin. Although many studies have been carried out on the structure, up-to-date information and data on the chemical-physical decomposition processes that have occurred on the material over the years are lacking. In order to fill this gap and provide basic information for the proper preservation of the structure, the Mor Yakup Church was analyzed. This structure is important in that it is the first university of education in the world that has survived to the present day. In this study, field studies and laboratory studies were carried out to determine the textural, physical, chemical, mineralogical and mechanical properties of the material used in the building, and the changes it has undergone over the years. The weathering pattern, forms and profiles show that the limestone deteriorates due to the cement-containing mortars used in the building and environmental effects (especially from the exhaust gas effect). It has been determined that nitrate salt has a role in the intense black layering, which can be observed visually, especially on the stone surfaces.
