  • 3D characterization of weathered building limestones

    Research highlights 3D image analysis can be used to quantify the modification in the porous structure of weathered limestones For the studied sample, weathering caused an increase in porosity (notably by cracks), removed silica grains from their settings, induced below the surface some constraints on the solid phases, and locally compacted the grains A weathering criterion is proposed
