Muping Grey Granite

Muping Grey Granite is a natural stone quarried in the Shandong province of China. It is known for its stable, light-to-medium grey backdrop, which is accentuated by fine black and white mineral peppering, giving it a unique and elegant appearance. This granite is a popular choice for a variety of architectural and design applications due to its aesthetic appeal and durable nature.

Physical and Mechanical Properties

• Water Absorption: Typically ranges from 0.2% to 0.4% depending on the specific batch of granite.

• Density: Generally around 2.65 to 2.73 g/cm³, highlighting its solid and durable structure.

• Flexural Strength: Approximately 12 to 14.5 MPa, which makes it suitable for flooring and cladding applications.

• Compressive Strength: Generally between 165 to 185 MPa, indicating a robust stone that can withstand significant pressure.

• Hardness: Measures about 6 to 7 on the Mohs scale, reflecting its resistance to scratches and wear.

• Porosity: Characterized as low, due to its dense nature, which helps in reducing water absorption and increasing durability.

• Slip Resistance: Varies based on the finish; a polished finish will generally have lower slip resistance compared to honed or flamed finishes, which are more slip-resistant due to their texture.

Chemical and Mineral Compositions (by weight)

• Silica (SiO2): Approximately 65% - 75%
• Alumina (Al2O3): Around 14% - 15%
• Iron Oxide (Fe2O3): Typically 1% - 3%
• Calcium Oxide (CaO): Roughly 1% - 2%
• Magnesium Oxide (MgO): Often 0.5% - 1%
• Potassium Oxide (K2O): About 4% - 5%
• Sodium Oxide (Na2O): Approximately 3% - 4%

Usage

• Indoor Flooring and Wall Cladding: Its aesthetic appeal and durability make it ideal for high-traffic areas.
• Countertops: Resistant to scratches and staining, making it suitable for kitchen and bathroom applications.
• Outdoor Paving and Landscaping: With its slip resistance and weather resistance, it is a great choice for patios, driveways, and garden pathways.
• Monuments and Sculptures: Its ability to be polished to a high gloss makes it fitting for artistic and memorial structures.

Maintenance

• Cleaning: Regular cleaning with mild soap and water, avoiding harsh chemicals to protect the surface.
• Sealing: Periodic sealing is recommended to enhance resistance to stains and etching.
• Avoiding direct contact with acidic substances: As with all natural stones, acids can damage the surface over time.

Cutting Sizes (common in centimeters)

• Tiles: 30x30, 30x60, 60x60
• Slabs: 120x240, 150x300 (can vary based on manufacturer or quarry availability)
• Customized sizes are often available upon request for specific projects.

Common Surface Finish Options

• Polished: Provides a glossy, reflective surface showcasing the stone's color and pattern.
• Honed: Offers a smooth, matte finish that is less reflective.
• Flamed: Offers a rough texture, providing better slip resistance, ideal for outdoor use.
• Bush-Hammered: Produces a textured surface with a rugged appearance.
• Sandblasted: Offers an evenly textured non-slip surface.

Muping Grey Granite's blend of aesthetic versatility and robust physical properties makes it a preferred choice for architects and designers worldwide. Whether used in modern interiors or classic exteriors, it offers a timeless beauty coupled with practicality.
