Assessment of the efficiency of various consolidation agents based on the evaluation of changes of material properties of plaster from the Imperial Palace in the Karlštejn Castle
Slížková, Zuzana ; Drdácký, Miloš ; Hasníková, Hana ; Frankeová, Dita
The report describes the procedure of assessment of efficiency of four consolidation agents used on plaster from the Imperial Palace in the Karlštejn Castle. It includes photographic documentation and all the results with final evaluation and conclusion. Three non-destructive methods were used in-situ in the Karlštejn Castle – water absorption measurement by Karsten tube, water absorption measurement by microtube and so called peeling test. The locations and way of taking samples are mentioned in the report also. Mechanical tests, (compression test, three point bending test) have been performed on the samples and also bulk density, open porosity and water absorption of treated and untreated material according to ČSN EN 1015-10 have been investigated in laboratories of ITAM AS CR.
