Hydrofobizacja opoki wapnistej w obiektach zabytkowych Kazimierza Dolnego

Abstract

The scientific aim of work is determination of technological and restoration possibilities in use of silica-organic compounds in repairs of monuments built of Kazimierz stone which are necessary to improve its resistance against damaging activity of water. In this work a series of analyses were conducted to prevent unhomogenous and porous structure of the rock from damaging activity of rain water by hydrophobisation. Another part of this work is determination of procedures before decision of hydrophobisation processes. Examinations present the influence of silica-organic, hydrophobic agents on moisture parameters of Kazimierz limestone. The hydrophobic layers property analysis was conducted in the structure of five different chalkrock specimens. Examinated material is the calcium silicate stone used in building of XVI-th century monuments of Lublin site and rock from Kazimierz Dolny quarry which can be used as a restoration material. The hydrophobisation processes subjects are five kinds of siliceous limestone differing in parameters which influence the procedure effects, for example differing in geographical orientation (different insolation, frequency of freezing – melting cycles), salinity, area of origin.
