Research explores CO2 mineralization impacts on basalt's physical and mechanical properties, suggesting insights for geologic storage applications.

The study aims to characterize the CO2 mineralization rate and its effects on the physical and mechanical properties of basalt.
Conducted experiments in a self-designed rock reactor.
Used standard cylindrical basalt samples under 12 MPa and 70°C.
Measured CO2 consumption over various reaction times (0, 10, 20, 30, 60 d).
Developed a theoretical CO2 consumption calculation method.
Validated results against actual consumption data from weight changes.
CO2 consumption fitted with a double exponential function showing a peak reaction rate followed by a decline.
Altered physical and mechanical properties include changes in porosity and strength metrics.
Increased porosity and decreased mechanical properties noted with longer reaction times.
Siderite and calcite precipitated, but rock dissolution was dominant.

Pan et al. (2026) studied this question.
