Engineering uses of granite and marble
Short answer
Granite is used for foundations, bridge piers, retaining walls, dams, crushed aggregate for concrete, road metal, and polished slabs for facing and flooring. Marble is employed as a decorative stone for flooring, wall cladding, steps, columns, and monuments because it takes a fine polish; crushed marble serves in terrazzo and lime production.
Outline the engineering uses of granite and marble.
Granite
- Foundations, bridge piers and abutments, retaining walls and dams, because of high strength and durability.
- Crushed to aggregate for concrete, road metal and railway ballast.
- Polished slabs for facing, flooring, steps, kerbs and monuments.
Marble
- Decorative flooring, wall cladding, steps, columns, statues and monuments (takes polish).
- Crushed for terrazzo flooring and as filler; used in lime and cement industry in some areas.
- Not suitable for external use in acidic environments.
