TL;DR: In this article, a set of 44 samples of plastered elements used in the Portuguese architecture belonging to a time period of 2 centuries was studied, and compositional patterns with a direct relation to the type of application: smooth surface thin-layer plasters, moulded on site and pre-moulded elements.

TL;DR: In this paper, the physical and mechanical properties of 44 ancient gypsum-based plaster samples are studied for the design of compatible solutions to be used in restoration and conservation interventions.

TL;DR: In this paper, the process of design and evaluation of compatible materials to partially or completely substitute damaged interior walls and ceilings coatings made of gypsum-based plasters is presented and the results obtained are discussed.

TL;DR: In Portugal, a large number of vernacular earthen buildings present an advanced state of degradation due to their historical, technological, architectonic, cultural and social recognizability as mentioned in this paper.

TL;DR: The characterization of a gypsum plaster sample from the end of the 19th century simulating imperial red porphyry using a multi-analytical approach is presented and discussed, providing important information about the materials, the skills, and the technological development involved in the art of imitating noble stones with Gypsum pastes.
