Description
Branco Gris Granite is a hypidiomorphic granular crystalline granite primarily composed of quartz, orthoclase, and plagioclase feldspar with some biotite mica. It features a tightly interlocked fine-to-medium grain pattern with a predominantly grey color palette, ranging from medium to light grey, often interspersed with subtle white highlights and occasional darker mineral flecks. This granite is quarried in Portugal, specifically in Maria Ribeira, Tapada dos Veados, Santa Eulália (Elvas), in the Distrito de Portalegre.
Physical and Mechanical Properties:
- Water Absorption: 0.19% by weight
- Density: 2643 kg/m³
- Flexural Strength: 15.68 - 16.0 MPa
- Compressive Strength: 145.0 - 165.0 MPa
- Hardness: Generally falls between 6 and 7 on the Mohs scale (though specific hardness may vary)
- Porosity: Low; the granite is considered dense and less porous
- Slip Resistance: Usually good; can vary based on the surface finish
Chemical and Mineral Composition (% by weight):
- Quartz: 35%
- Orthoclase (alkali feldspar): 25%
- Plagioclase: 30%
- Biotite mica: 9%
- Others: 1%
Exact percentages may vary slightly based on the specific location and depth within the quarry.
Usage:
- Ideal for indoor and outdoor applications including countertops, flooring, wall cladding, stairs, and monuments.
- Suitable for both residential and commercial spaces due to its durability and aesthetic appeal.
Maintenance:
- Regular cleaning with mild soap and water to maintain its appearance.
- Sealing is recommended every 1-2 years to enhance stain resistance, especially for countertops.
- Avoid using acidic or abrasive cleaners which can dull the surface.
Surface Finish Options:
- Polished: Enhances the stone's natural colors and patterns, giving a high-gloss finish.
- Honed: Provides a smooth, matte finish ideal for more subtle aesthetics.
- Flamed: Creates a rough texture, improving slip resistance, commonly used outdoors.
- Brushed: Offers a slightly textured surface, combining the aesthetics of honed and flamed finishes.
Branco Gris Granite is a versatile and durable stone suitable for various aesthetic and functional applications, maintaining its integrity and appearance with proper maintenance over time.
