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.

The Church of the Company of Jesus in Quito (1605–1765) is one of the most remarkable examples of colonial religious architecture on the World Heritage List. This church has multiple constructive phases and several interventions with no clear record of the entire architectural site, including the historical mortars. A total of 14 samples of coating mortars inside the central nave were taken, with the protocols suggested by the research team and a comparative sample of the architectural group that does not have intervention. The analysis presented in this paper focuses on mineralogical characterization, semi-quantitative analysis by X-ray diffraction and scanning electron microscopy with microanalysis of the samples. The results showed the presence of volcanic aggregate lime and gypsum, used in lining mortars and joint mortars. Mineralogical and textural composition data have allowed the mortar samples to be relatively dated.

The aim of this paper is to propose a workflow for the real-time visualization of virtual environments that supports diagnostic tasks in heritage buildings. The approach integrates data from terrestrial laser scanning (3D point clouds and meshes), along with panoramic and thermal images, into a unified virtual model. Additionally, the methodology incorporates several post-processing stages designed to enhance the user experience in visualizing both the building and its associated damage. The methodology was tested on the Medieval Templar Church of Vera Cruz in Segovia, utilizing a combination of visible and infrared data, along with manually prepared damage maps. The project results demonstrate that the use of a hybrid digital model—combining 3D point clouds, polygonal meshes, and panoramic images—is highly effective for real-time rendering, providing detailed visualization while maintaining adaptability for mobile devices with limited computational power.

The religious art of the Dominican order is reflected in Santo Domingo Church, which was built between 1541 and 1688. This work of heritage architecture, one of the first to be built in the colonized city, was affected by multiple earthquakes, interventions, and constructions that have not been clearly recorded. A total of 13 samples were taken from the mortar inside the cloister, central nave, and side chapel, following the minor destruction-testing protocols and standards suggested by the research team. The analysis included mineral characterization studies and quantitative analysis by X-ray diffraction, petrographic, and scanning electron microscopy with microanalysis of the samples. The results showed the presence of volcanic aggregates and lime mortars, mortars of rustic composition and coarse manufacture. The results of mineralogical data and texture have allowed us to corroborate the historical information described by the chroniclers, to date relatively studied sites and to establish a hypothesis of constructive stages.
