Pomiary wilgotności murów z kazimierskiej opoki wapnistej przy zastosowaniu metody TDR

The article presents monitoring measurements of the physical parameters and mineralogical-petrographical composition analysis of the chalk rock from the Kazimierz Dolny region. The experiments involve the reflectometric techniques TDR (Time Domain Reflectometry) as a perspective alternative in moisture determinations. The investigation domain was the stone from the Castle of Janowiec by the Vistula river, which walls indicate the progressive corrosion depending on external exposition and age. Other object of investigations was the stone from quarry in Kazimierz Dolny. Porosimetric examinations of the chalk rock from the southern and northern elevation of the castle indicate differences in structure changes of the stones. These differences influence different behaviour of the chalk rock during capillary rise of water and salt solutions. It is connected with the suitable matching of the conservation protection, wall protecting preparations which kind and application depend on porosimetric parameters of the material. The TDR method is applied as a good alternative of water transport measurement in porous building materials and other water parameters characterisig described material.
