Physical property evolution of granite during experimental chemical ...

Specifically, we investigate how the physical (porosity, permeability, mass) and mechanical (compressive strength, Young's modulus) properties of granite may evolve over time, when exposed to different acid environments. We use chemical and microstructural analyses to interpret the operative mechanisms at work during our experiments.
