Application of Herzegovinian dolomite as dimension stone
In general, dolomite is a stone of medium high/ high compressive strength, with low water absorption, low porous. By bulk density, it is a heavy stone, and by wear resistance it is a hard stone, but also moderately hard in some cases. All this should be taken into account when using these dolomites.
