Comparison and Use of Hg Porosimetry and X-ray Computed Microtomography in Durability Tests of Sandstone on the Charles Bridge in Prague
Original language description
Sandstones were often used as dominant building material in medieval Prague. Weathering processes lead to deterioration of these dimension stones and to changes in their durability. The range of the deterioration depends on petrography, including internal structure, mineral composition and cementation type, and also changes initiated. A special weathering simulation program was developed to enable study the durability of sandstone in Prague winter climatic conditions. The Kocbeře cretaceous sandstone used for the last reconstruction of the Charles bridge in Prague was tested during this experiment. Changes developing in the internal structure were determined by Hg porosimetry and X-ray computed microtomography. The relationship between uniaxial compressive strength and porosity were studied during this experiment. It was ascertained that the decrease of uniaxial compressive strength is accompanied by growth of the volume of closed pores.
