The samples were characterized by means of mercury intrusion porosimetry (MIP) and total-specific-area analysis (BET). A good agreement was achieved between the samples of the brick and mortar from the Bač Fortress,or the samples of the natural stone and render from the Dornava Manor, and the corresponding model samplesPrispevek obravnava mikrostrukturne lastnosti izbranih materialov iz dveh objektov kulturne dediščine (dvorec Dornava v Sloveniji in trdnjava Bač v Srbiji) ter modelnih materialov - kontrolnih in staranih. Vzorce smo preiskali z živosrebrno porozimetrijo in plinsko sorpcijo. Med vzorci iz objektov kulturne dediščine in modelnimi vzorci smo dosegli dobro ujemanje, tako v primeru opeke in malte s trdnjave Bač kot naravnega kamna in ometa z dvorca DornavaTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
