Studies in ancient gypsum based plasters towards their repair: Physical and mechanical properties (original) (raw)

Abstract

h i g h l i g h t s 44 samples of gypsum plasters from a time period of 2 centuries were studied. The main binders used were calcium sulphate hemi-hydrate and lime putty. 3 compositional patterns, characterised by 3 different ranges of the 2 main binders, were identified. The type of application, composition and microstructure are related. Higher quality raw materials and techniques were used in most valuable buildings.
