Strengthening of poor lime mortar with consolidation agents

Popis výsledku v původním jazyce

Lime water treatment on a specific lime mortar was tested and evaluated for effectiveness, showing that after a sufficiently high number of applications (160 cycles, 54-80 days of a permanent consolidation treatment) some of the poor mechanical characteristics (compression and surface cohesion) were substantially improved. The lime water treatment was also compared with some other less labour-intensive technologies. The most efficient agents were dispersions of calcium hydroxide in alcohols, which are marketed under the trade name CaLoSiL by the German producer IBZ Freiberg. The major advantage with these agents is that they can be applied much more rapidly than tens to hundreds of lime water cycles and they deliver a higher amount of lime in each cycle. While lime water contains only small calcium ions, sized about 0.1 nm, calcium hydroxide particles in CaLoSiL are considerably larger (50-200 nm). This property makes the use of these nanolime dispersions limited to structural consolid
