Abstract: In 2016, the CEG Association (Center d’estudis del Guix) visited the region of Pallars with the intention of making a traditional kiln with the autochthonous stone found in the area and then to obtain a traditional plaster product from it. Once the traditional kiln was built and the processes of calcination and crushing of the stone were finished, approximately half a ton of traditional plaster was obtained, which was stored in bags of 25 kilograms each.
In the year 2017, it was decided to carry out the physical-mechanical characterization from the traditional gypsum product obtained in the region of Pallars. Furthermore, looking for a point of comparison, it was decided to carry out also the physical-mechanical characterization of the traditional gypsum of Albarracín. The last one, probably is the only traditional gypsum which is commercialized in Spain.
As a result of this, the question arises as to whether the traditional plaster of Pallars has sufficient physical and mechanical properties to be able to compete with the traditional commercial plaster of Albarracín.
