Research report. Experimental study of effects of various consolidants on mechanical characteristics of historic lime render
Slížková, Zuzana
The chemical-physical properties of the historical lime render to be restored were tested and then the tests of consolidation effects using liquid consolidants based on ethyl silicate and nano-calcium dispersion were performed. The highest strengthening effect was achieved by double treatment of the render with product Remmers KSE 300 (based on ethyl silicate). Due to the required hydrophilic properties of the render after consolidation, the final treatment of the render with a nanolime suspension, eg CaLosil IP 15 or CaLoSiL E 25, was recommended.

The report contains the results of the material analyses of plasters and stone samples taken from the facades and interior plasters of the historical building named “Nové Probošství” (Pražský hrad, nám. sv. Jiří č.p. 34).). The topic of the study was determination of the chemical composition and the microstructure of historical plasters and renders, sandstone petrography, porosity of materials by means of MIP, water absorption of plasters by tubes, the water content and the moisture distribution in masonry wall, the content and the chemical composition of water-soluble salts in plasters and renders. The results of the study serves as the basis for the future design of the building renovation and the restoration of the artistic elements.\n
