Brown Qussair Granite Overview

• Origin: Quarried in Al-Quseir, Egypt
• Appearance: Medium to coarse-grained texture with a pale brown base color interspersed with earthy gray grains.

Physical and Mechanical Properties

• Water Absorption: 0.3 – 0.6%
• Density: 2650 – 2750 kg/m³
• Flexural Strength: 12 – 18 MPa
• Compressive Strength: 130 – 170 MPa
• Hardness: Granite generally has a Mohs hardness of about 6 to 7, indicating good resistance to scratching and wear.
• Porosity: Generally low, enhancing its durability and resistance to staining.
• Slip Resistance: Depends on the surface finish; polished finishes can be slippery when wet, while honed or flamed finishes offer better traction.

Chemical and Mineral Composition

• Quartz: 20-40%
• Feldspar (Orthoclase and/or Plagioclase): 30-60%
• Mica (Biotite and/or Muscovite): 10-15%
• Others: Traces of minerals such as hornblende, pyroxene, and garnet may be present depending on specific quarry samples.

Usage

• Internal Applications: Flooring, countertops, wall cladding, and decorative features.
• External Applications: Facades, pavements, and outdoor decorative elements due to its durability and weather resistance.
• Landscaping: Used for garden features, benches, and steps.

Maintenance

• Regular cleaning with mild soap and water is recommended.
• Seal periodically, particularly in high-use areas, to maintain appearance and stain resistance.
• Avoid harsh chemical cleaners and abrasives.

Cutting Sizes (cm)

• Common slab sizes:
• 240 x 120 cm
• 260 x 160 cm
• Tile sizes can vary depending on design requirements.

Surface Finish Options

• Polished: Provides a high-gloss, mirror-like finish that enhances the color and pattern but may be slippery when wet.
• Honed: Offers a smooth, matte finish with reduced glare and better slip resistance.
• Flamed: A rough surface finish created through high-temperature treatment, improving slip resistance for outdoor use.
• Bush-Hammered: Textured finish achieved through mechanical processing, suitable for non-slip surfaces.
• Leathered: Soft, textured finish that offers warmth and a more natural appearance.

Brown Qussair Granite is prized for its aesthetic appeal combined with notable strength and versatility, making it suitable for a wide range of architectural and design applications.
