Description
  • A method for the prediction of the degradation problems of sedimentary porous rocks in historical buildings, which has not been frequently used until now, is presented. It consists of a combination of computational and experimental approaches. In the experimental part, durability of the rocks is determined in terms of their frost resistance. In the computational part, a diffusion-type model is used for the description of coupled heat and moisture transport aimed at the identification of the number of frost cycles in a real structure. The prediction of moisture and temperature fields in the envelope parts of historical buildings over a sufficiently long time makes it possible to not only make a reliable estimate of the service life of the applied rocks on the basis of a sufficient amount of input parameters, but also to create a design of the time schedule of possible repairs. As a practical example, several historical walls composed of different types of sandstone are chosen. The influence of the different material parameters of the sandstones on their service life is analyzed, depending on the environmental conditions in a given locality. Conclusions are drawn on the most advantageous type of sandstone for the particular locations with respect to service life.
