چکیده
This work presents a corpus of measurement methodologies utilized during multidisciplinary project, aiming at the protection and conservation ancient steel joints (clamps dowels) Acropolis monuments, undertaken by Restoration Service (YSMA). The Laboratory Physical Chemistry National Technical University Athens collaborated with YSMA in designing evaluating laboratory scale field experiments, testing materials. first phase involved application seven coating systems on uncorroded metal coupons. characteristics, physicochemical properties (colour, gloss, hydrophobicity), performance against accelerated corrosion polymer photo-oxidation were measured. Poligen CE12 Paraloid B67 +2% nano-alumina selected as two most suitable materials for pilot applications corroded outdoor exposure monument site. assessment coatings reversibility surfaces chemical alteration was Raman spectroscopy analyses orthophotographic documentation. During 1-year exposure, development retarded, but some local events active could not be prevented. joint areas coated enhanced 2% enabled more uniform exhibited better protection. In case CE12, nature products indicated acceleration reactions.
