The traditional gypsum of Albarracín is probably the only one currently marketed in Spain. In the Pyrenees of Lleida, specifically in the regions of Pallars Jussá and Pallars Sobirá, the traditional constructions are carried out, mainly with traditional plaster. In order to obtain a traditional gypsum that presents properties similar to those of Albarracín, a traditional oven was built in the Pyrenees of Lleida in 2016, in Senterada (Pallars), obtaining a product of 500 Kg of plaster after cooking. The present work shows a comparative through an experimental study, at a physical-mechanical level, of the two traditional gypsums, with different water/plaster dosages and with different mixing times. The results show many similarities between both materials and demonstrated, once again, how the manufacturing factors can affect them.
