Project description

Countering salt damage by controlling rock dynamics through mesoscopic analysis

Cyclic changes during rock weathering or at geothermal or CO2-sequestration sites lead to precipitation-dissolution cycles of salts, natural constituents of brines inside rocks, which might degrade rocks’ structure. What triggers rock dynamics up to fracturing during salt precipitation? Can we ultimately control this trigger? The EU-funded PRD-Trigger project advocates that the answer lies at the mesoscale, the scale of the pore network. It will combine 4D X-ray imaging with a mesoscopic numerical simulator integrated into the image analysis workflow to identify key factors in precipitation-induced damage. Damage control and crack healing will then be demonstrated on core-scale rocks. These advanced methods could be used to increase durability of building stones, to protect historic monuments, or to optimize geoengineering techniques.
