Repairing of Damaged Stone in Monuments and Stone Buildings

Advances in Science and Technology, 2010
The main causes of rock degradation in stone buildings are discussed and the current methods of recovering damaged stones are summarized. The Alkaline Activation seems to present a great potential to deal with particular cases of damaged stones resulting mainly from fracture incidents provoked by physical actions, where the global substitution of the ...

Stone Monuments Consolidation with Nanomaterials

Key Engineering Materials, 2015
Historical monuments suffer different forms of degradation, due to some improper works on architecture structure, vibrations caused by blasting, traffic, the inadequate restoration, the phenomenon of freeze-thaw, air pollution, humidity and temperature variations, friable mortar, deposits adhering impurities (dust, smoke, tar), soluble efflorescence ...

Stone Materials of the Necropoleis Monuments

2018
Based on the results of many years of monitoring, the unique stone material of tombstones in the historical Necropoleis of the Museum of City Sculpture is described, represented by marbles, limestones, granites and other rocks. The most probable locations of deposits of the used decorative facing stone were in most cases identified with the help of ...

Microbial melanins in stone monuments

Science of The Total Environment, 1995
In polluted environments, black deposits on the surface of building stones have traditionally been considered a result of fossil fuel combustion. This has been supported by SEM observations and EDX analyses of gypsum black crusts as well as by chemical characterization of the organic compounds.

Bioconsolidation of Stone Monuments. An Overview

Restoration of Buildings and Monuments, 2016
Abstract This article reviews the carbonation process through biomineralization referred to as Microbial Induced Calcium Carbonate Precipitation (MICCP) for the conservation of carbonate stone monuments and historic building materials. This biological process widely occurs in nature as microbes produce inorganic materials within their ...

Origin of films on monumental stone

2008
This paper investigates the origin of superficial films on different rock types from rural and urban locations in Spain and Ireland, focusing mainly on oxalate films. There is little agreement on the origin of oxalate films coating building stone. Some authors state that they are man originated whereas others claim that they are naturally produced by ...

Stone Conservation on Buildings and Monuments

1973
The rapid, visible decay of stone in urban areas has made it necessary to protect stone surfaces from premature decay; the attempt is to halt the natural process of stone decay but we can merely slow down nature’s continuous gnawing. Protective commercial chemicals have been applied since the 17 th century. The heterogeneity of stone, however, does not
