Mineralogical and microstructural characteristics of historic Roman cement renders from Budapest, Hungary

Popis výsledku v původním jazyce

Roman cements were one of the most extensively produced types of hydraulic binders of the second half of the 19th century. This paper deals with the chemical-mineralogical and microstructural characterization of historic Roman cement renders from Budapest. Different microscopic techniques were used on polished thin sections and fracture surfaces in order to understand the method of producing these renders and the effect of urban pollution on them. The renders exhibited characteristics typical to a Romancement mortar, such as high binder to aggregate ratios and high capillary porosity, but without the shrinkage cracks. Despite exposure to a polluted urban environment, which resulted in formation of gypsum on the surface of the renders, the samples showgood to excellent state of preservation after more than a century. The strong "house of cards"-like arrangement of the complex C-(A)-S-H-type phases is responsible for both the high capillary porosity and the good resistance of Roman cem
