AB Santa Pudia calcarenite was one of the most commonly used building materials in the construction of historical buildings inthe city of Granada (Spain). As a result, Santa Pudia calcarenite has been mainly studied from a petrographical point of viewin previous works. In this work, the mechanical properties of Santa Pudia calcarenite are studied. The main mechanical properties(compressive strength, elastic modulus and Poisson’s ratio) were determined using the corresponding tests. Samplesof Santa Pudia calcarenite were heated at 550 °C to study the effect of high temperatures on its compressive strength. Twodifferent cooling methods were considered: air-cooling and water-cooling. Stress–strain curves of heated and non-heatedsamples were obtained from uniaxial compression tests. Creep is of great importance in the long-term structural assessmentof historical buildings. To study the creep behaviour of Santa Pudia calcarenite, samples were subjected to uniaxial compressivetests at constant stress until the stabilization of the recorded strains was reached. Different rheological models wereadjusted to the experimental results to simulate the long-term behaviour of the material studied. The instantaneous responseto additional loadings on the samples (maintaining the long-term loading and deformation) were also studied. Results showthat a Santa Pudia calcarenite specimen subjected to dead loads will suffer a higher instantaneous deformation against asudden load than a non-preloaded specimen. This degradation effect can be particularly important in the case of a seismicevaluation of historical buildings.
