Abstract Summary
The objective of this work is to characterize synthetic carbonate rocks, mainly composed by calcite, through microtomography and petrography, focusing on a comparative analysis before and after load application and chemical degradation. Dissolution tests were performed in a modified oedometer cell adapted to measure horizontal stress. Dissolution was conducted using an acid solution (10% acetic acid) to evaluate the influence of the pH on the mechanical behaviour of the samples. A model for degradation of carbonatic soft rocks based on critical state theory was used to reproduce the observed behaviour in experiments where mechanical and chemical loads are applied.
