Characteristics of stones - CivilEngineeringBible

A dull, chalky and earthly fracture of a stone indicates signs of early future decay. Specific gravity: For a good building stone, its specific gravity should be greater than 2.7 or so. The heavy stones are more compact and less porous and they can be used for various engineering applications such as dams, weirs retiming walls, docks, harbours etc.
