Characterization of Mortar from Casa Barbot (Portugal), a Case Study from the Beginning of the 20th Century

The popularity of natural cement (Roman cement) in buildings from the late 19th and beginning 20th century high diversity characteristics demand research mortar binders used this period Portugal. Understanding type binder historic will help project/intervention team to make best decisions terms development compatible mortars for historical conservation purposes. Casa Barbot is one Art Nouveau examples garden building characterized by peculiar elements materials architecture. Full characterization employed construction as well identification main objective study. study comprises a wide range laboratory techniques such X-ray fluorescence (XRF), diffraction (XRD), petrography, open porosity, density, water absorption capillarity, compressive strength. results show compositional decorative Barbot. All are composed Portland with mix additives blast furnace slag, limestone filler, air lime, occasional presence charcoal. raise doubt about use stated documents. This broaden scientific knowledge that Portugal provide comprehensive plan preservation buildings.
