This analysis reveals how crystallisation pressure varies in porous media with compliant crystals, suggesting new insights into geochemical processes.

Key Points

The aim is to revisit the Correns equation for crystallisation pressure using poromechanics to enhance understanding of crystal growth in porous media.
Established a theoretical framework integrating principles of physical chemistry and thermodynamics.
Incorporated generalised poroelasticity to account for crystal and matrix stiffness.
Conducted parametric analyses examining the effects of crystal and skeleton compliance on crystallisation pressure.
Higher pressure results from less stiff crystals during crystallisation.
Greater crystal growth is accommodated by more compliant porous skeletons.
Significant strain is observed within crystal phases, especially with compliant secondary solids.
