Abstract
The main purpose of this work is to analyze the elastic properties (i.e. Young’s modulus and Poisson’s ratio) of gypsum specimens manufactured by traditional methods (non-industrial kilns). More specifically we have evaluated the Bajo Aragon variant by means of a low-cost digital image correlation approach. The accuracy of the data was contrasted with the press, obtaining an RMSE of 0.008%, corroborating the viability of the method. The results obtained during this experimental campaign revealed a gypsum with an average compressive strength, Young’s modulus and Poisson’s ratio of 4.01 MPa, 2989 MPa and 0.24 respectively.
