The material undergoes various temperature gradients ( 20 and 300ºC) in sets of daily accelerated aging cycles (100 cycles). The results illustrate the impact of thermal gradients and reveal a decrease in the material’s mechanical properties of up to 24%. Moreover, the reduction observed in the initial cycles at lower gradients (50 cycles, 20/50ºC) continues to progress with the increasing intensity and number of cycles. Changes induced in the microstructure manifest as microcracks between calcite grains. The correlation coefficient R2 > 0.9 confirms the effectiveness of non- destructive tests as reliable techniques for assessing the material’s strength capacity and potential deterioration 2024-05-06T07:07:05Z 2024-05-06T07:07:05Z 2024-02-07 info:eu-repo/semantics/article M.P.
