Abstract
This study attempted to apply a hybrid technology that integrated mineral-based fillers and water-repellent agents to control the efflorescence that results from the use of inorganic binders, for the conservation treatment (surface finishing) of cultural heritage materials made up of stone. Herein, different types of mixing ratios of a filler (silica fume 3.4%) and a water repellent (silane-siloxane 1%) were selected for fabricating the inorganic binder, and it was determined that the ratio selected by weight is effective in controlling efflorescence substances. In addition, it was identified that the inorganic binder with the mixing ratio resulted in a higher compressive strength than the standard (20MPa), and the water permeability resistance was high with low water absorption. The result of ion elution from the bilder showed that a smaller number of ions was observed to affect the efflorescence (directly and indirectly) as compared to that of the control group, which was considered to be relatively stable.
