Lime-based historic plasters characterization: mineralogical composition and binder to aggregate ratio
Original language description
Preserving historic buildings requires renovation using compatible plasters that closely resemble the original ones. However, achieving this likeness requires a thorough characterization of the original plaster. This article explores the challenges of characterizing historic lime-based plasters from two architecturally interesting buildings in the Czech Republic dating back to the first half of the 20th century. Key issues include the determination of the binder-to-aggregate ratio, the fine aggregate particle size distribution, the mineralogical composition, and the degree of lime plaster carbonation. Experimental methods include X-ray diffraction analysis (XRD), pH-value determination, hydrochloric acid dissolution of binder components, sieve analysis, thermogravimetric analysis (TG), and differential scanning calorimetry (DSC). The tested plasters are compared, and the effectiveness of various approaches is evaluated. The binder-to-aggregate ratios are approximately 1:5. The plaster from one of the buildings was almost pure (lime binder + aggregate), while the second one contained other components, such as calcium silicate hydrates, gypsum, and magnesium phases.
