Origin and growth of weathering crusts on ancient marbles in industrial atmosphere
TL;DR: In this article, the origin and growth of weathering crusts on the ancient marbles of ruins of the Sanctuary of Demeter in the industrial atmosphere of Eleusis in Greece have been investigated.

Chemical relations between atmospheric aerosols, deposition and stone decay layers on historic buildings at the mediterranean coast
K. Torfs,R. Van Grieken +1 more
TL;DR: In this paper, the effects of the environment on weathering of historical buildings in the Mediterranean Basin, an elaborate study has been carried out at four monuments, with specific interest directed on the action of air pollution and marine salts.

Accelerated microstructural evolution of a calcium-silicate-hydrate (c-s-h) phase in pozzolanic pastes using fine siliceous sources: comparison with historic pozzolanic mortars
TL;DR: In this paper, a microstructural analysis revealed an enhanced reaction rate but similar morphologies of the resultant C-S-H phases, confirming that the reaction-limiting factor is the dissolution of the siliceous sources.

Effect of stone thickness on run-off water composition and derived damage functions in ambient exposure experiments
K. Torfs,R. Van Grieken +1 more
TL;DR: In this article, a damage function was constructed to explain the Ca 2+ loss for both stone thicknesses as a function of rain input and environmental conditions and showed that the absence of correlations between atmospheric conditions and stone decay during short time intervals (e.g. 1 d) does not appear to be due to retention of ions in the stone.

Use of Stable Isotope Measurements To Evaluate the Origin of Sulfur in Gypsum Layers on Limestone Buildings
TL;DR: The feasibility of applying sulfur isotope measurements to elucidate the origin of sulfur and the mechanism of crust formation on monuments has been investigated in this article, where relatively large variations of the 34S/32S ratio have been found in gypsum crusts on monuments situated in the center of Antwerp, the suburbs, and the surrounding area.
