Tests on sustainability of consolidation treatments with CaLoSil nanosuspensions on plaster reference samples

Abstract

The main task of this study was to evaluate novel group of materials based on nanosuspension of calcium hydroxide and calcium hydroxide combined with calcium sulphate which should be used for consolidation of calcerous materials. This research has focused on assessment of consolidation on highly corroded pure lime and gypsum plaster. The evaluation was made through comparison of selected physical, mechanical and microstruce properties. The main task was to assess resistance of consolidated substrates to conditions following the external environment, especially the freeze-thaw cycles, resistance to the salts and humid-air conditions.
