The presence of red-brown garnet inclusions adds warmth and visual interest to the stone, making it a popular choice for various architectural and design projects.
Physical and Mechanical Properties:
- Water Absorption: 0.14%
- Density: 2720 kg/m³
- Flexural Strength: 17.92 MPa
- Compressive Strength: 172.0 MPa
- Hardness: Typically measured on the Mohs scale, granite has a hardness of around 6-7.
- Porosity: Generally low, but specific values may vary slightly due to natural variations in the stone.
- Slip Resistance: Typically high, making it suitable for flooring applications, though precise values may depend on the surface finish.
Chemical and Mineral Compositions (% by weight):
- Silica (SiO₂): Approximately 70-75%
- Alumina (Al₂O₃): Around 12-15%
- Potassium Oxide (K₂O): 3-5%
- Sodium Oxide (Na₂O): 2-4%
- Calcium Oxide (CaO): 1-3%
- Iron Oxides (FeO & Fe₂O₃): 1-3%, contributing to the dark flecks
- Magnesium Oxide (MgO): 0.5-2%
- Titanium Dioxide (TiO₂): 0.5-1%
- Minerals: Quartz, feldspar (mainly orthoclase), biotite, and garnet.
Usage:
- Architectural Applications: Ideal for countertops, flooring, wall cladding, and staircases due to its durability and aesthetic appeal.
- Interior Design: Frequently used for fireplace surrounds, bathroom vanities, and as an accent stone in high-end residential and commercial projects.
- Outdoor Applications: Suitable for use in outdoor landscaping, garden paths, or as a building facade thanks to its resilience and weather resistance.
Maintenance:
- Cleaning: Regular cleaning with a mild detergent and water is recommended to maintain its shine and prevent staining.
- Sealing: Periodic sealing can help protect the granite from stains and enhance its longevity.
- Care: Avoid using harsh chemicals or acidic cleaners which can dull the surface over time.
Cutting Sizes (cm):
- Standard slab sizes generally vary, but commonly available dimensions are 240 cm x 120 cm up to 300 cm x 180 cm.
- Custom sizes can be cut to order based on project requirements.
Available Common Surface Finish Options:
- Polished: A glossy, reflective finish that enhances the natural colors and patterns.
- Honed: A smooth, matte finish that offers a more understated look.
- Flamed: A rough texture achieved by exposing the stone to high temperatures, suitable for slip resistance in outdoor applications.
- Bush Hammered: A textured finish created by hammering the surface, often used for non-slip outdoor environments.
