... The eastern half of the Iberian Peninsula is rich in gypsum outcrops, to which must be added the regions of Asturias, Valladolid, Palencia, Cádiz, Málaga, Seville and Córdoba. Adding these regions to the eastern, they represent a 58.5% of the total area of the Iberian Peninsula (Gárate Rojas, 1999;La Spina & Grau, 2020a;Bel-Anzué & Elert, 2021). It is therefore not surprising that in "gypsiferous Spain", a large part of the built heritage has been developed through the use of this traditional conglomerate. ...
... On the other hand, in traditional gypsum these same properties are highly variable, which allowed it to be used in many construction systems. The characteristics of this traditional binder are the heterogeneity of the raw material, which is accompanied by associated minerals depending on the place of extraction, what we know as "impurities"; the variability in the percentage of purity of the stone used; the heterogeneous firing at high temperature; the crushing of the fired material; the hardness acquired after laying; the strength; and the durability of the heritage (González- Sánchez et al., 2020;Mayo-Corrochano et al., 2022). ...
Until the second half of the 20th century, the traditional architecture of the Iberian Peninsula was directly linked to the resources available in its immediate surroundings, naturally diversification the built heritage throughout the territory. In its gypsiferous areas, we find a great versatility of construction systems in which the main binder used is traditional gypsum, although this material has been forgotten in the 20th and the 21st century architecture, meanwhile industrial gypsum currently plays a secondary role in the construction sector. Gypsum, like any traditional binder, is a material that is particularly sensitive to the amount of water with which it is mixed, which will be strongly linked to the technique of application, among other technological parameters. Thus, the final performance of the product is, among other things, a consequence of this water/gypsum ratio, as Francisco Arredondo states in some of his works. In them, the behaviour of an industrial gypsum is analysed as a function of the mixing water, relating it in turn to other parameters such as compressive strength, water absorption and bulk density. The aim of this work is to study the influence of the mixing water on the physical and mechanical properties of different traditional plasters, taking into account previous studies, the diversity of traditional uses of gypsum and current application techniques.
In traditional architecture, the construction systems used have always been linked to the material resources of the environment. In the areas of extraction of gypsum in the Iberian Peninsula, the use of this material as a conglomerant was not limited to the interior lining of vertical and/or horizontal walls or to interior decorations, as is the case today, but proved to be a very versatile material, which could be used both in structural elements and in finishing elements and decorations. This study shows the preliminary results of an ongoing research on the recovery of traditional gypsum pavements, where three types of traditional gypsum plasters with natural products such as collagen, coconut soap, potassium soap, vegetable oil and marshmallow root were tested. The hygroscopic behaviour of the treated samples has been evaluated from the capillarity water absorption and the contact angle, due to their high hygroscopicity. On the other hand, the density and porosity, surface hardness and thermal conductivity of the samples have also been determined.
