Study of the correlation of the mechanical resistance properties of Macael white marble using destructive and non-destructive techniques
Abstract The current research explores the influence of thermal gradients on the mechanical strength of Macael marble using both Non-Destructive Testing (NDT) and Destructive Testing (DT). 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.

Highlights The correlation system offers precise insight into the behavior of the Macael marble. The intensity of aging cycles gradient applied is crucial. NDT evaluates the state of decay of marble and helps to decide the conservation interventions. The intergranular behavior of marble as a result of thermal expansion after the first 25 cycles.
