  • Stabilisation of weathered limestone surfaces using

    Calcium carbonates and other constituents of limestone dissolve in acidic groundwater due to the rock's hydrophilic characteristics (RodriguezNavarro and Sebastian, 1996; Massey, 1999) This can result in embrittlement by internal or surficial mineral alteration and such weathering can strongly impact rock stability (Abbaszadeh et al, 2016)
