20.500.12556/DiRROS-17020 Characterisation of 20th century cementitious materials from selected cultural heritage structures in Slovenia This paper deals with the characterisation of cementitious materials from selected cultural heritage structures in Slovenia. The mineralogical–petrographic compositions of an aggregate, a type of binder and secondary minerals were studied via electron microscopy and X-ray powder diffraction. The porosity and pore network were determined using a mercury porosimeter. The results show that the aggregate of the samples was highly diverse, ranging from limestone, dolomite, quartz, feldspar and mica. The binder of the investigated samples was cementitious; either ordinary Portland cement was used, or ordinary Portland cement blended with ground granulated blast furnace slag was used. Some samples consisted of cement–lime binders. The investigated examples entailing cement materials for their construction contribute to a better understanding of the technology used to prepare historical cementitious and cement–lime mixtures. 20th century cementitious materials historical concrete cultural heritage 20. stoletje cementni materiali kulturna dediščina true false true Molecular Diversity Preservation International Angleški jezik Slovenski jezik © 2023 by the authors.
