Testing
- Water Absorption:
- 0.2 - 0.45%
- Density:
- 2670 - 2730 kg/m³
- Flexural Strength:
- 15 - 17 MPa
- Compressive Strength:
- 180 - 220 MPa
- Stone texture:
- a natural earthy palette of medium grey, brown, and dark mineral tones interspersed with black and white crystalline speckles that create a rugged and organic mountain-inspired appearance. Its overall look is bold yet balanced, with a consistent granular pattern and subtle tonal variations that reflect its natural geological formation rather than directional veining. The texture is medium- to coarse-grained and crystalline, with a dense igneous structure typical of granite, ensuring excellent durability, high compressive strength, and strong resistance to weathering
Description
Native Mountain Granite is an igneous rock characterized by a natural earthy palette with medium grey, brown, and dark mineral tones. It includes black and white crystalline speckles, creating a rugged, organic, mountain-inspired appearance. Its texture is medium- to coarse-grained and crystalline with a consistent granular pattern, avoiding directional veining. This bold yet balanced look reflects its geological origins and provides durability.
Physical and Mechanical Properties:
- Water Absorption: Typically low, around 0.2%-0.45%, contributing to its resistance to staining and moisture damage.
- Density: Approximately 2,670 - 2,730 kg/m³, indicating a compact, dense structure.
- Flexural Strength: Generally ranges from 15 to 17 MPa, providing good resistance to bending forces.
- Compressive Strength: Around 180 - 220 MPa, highlighting its ability to withstand substantial loads without deforming.
- Hardness: Granite typically features a Mohs hardness of 6-7, indicating significant scratch resistance.
- Porosity: Low porosity, usually below 1%, contributing to its durability and resistance to weathering.
- Slip Resistance: Varies by finish but generally provides moderate to high slip resistance, important for flooring applications.
Chemical and Mineral Composition:
Native Mountain Granite is composed of various minerals, typically including:
- Quartz: 20-40%
- Feldspar (Alkali Feldspar and Plagioclase): 40-60%
- Biotite and/or Muscovite: 5-15%
- Hornblende or Other Dark Minerals: 5-10%
- Accessory Minerals (including Magnetite, Zircon): <5%
Usage:
- Interior Applications: Kitchen countertops, bathroom vanities, flooring, walls, staircases.
- Exterior Applications: Facades, cladding, outdoor flooring, monuments, and garden features.
- Commercial Applications: Reception desks, tabletops, and in hotels or office buildings for aesthetic and functional purposes.
Maintenance:
- Regular cleaning with mild soap and water.
- Periodic sealing recommended to maintain appearance and resistance to stains.
- Avoid acidic or abrasive cleaners that could damage the surface.
Surface Finish Options:
- Polished: Highly reflective, enhancing the stone’s natural colors and patterns.
- Honed: Smooth, matte finish suitable for indoor spaces needing a subtler look.
- Flamed: Textured finish achieved by high-temperature treatment, ideal for slip resistance in outdoor settings.
- Brushed and Leathered: Soft, textured surfaces that enhance the stone’s color and are suitable for a variety of applications.
Native Mountain Granite excels in architectural and design applications due to its robust mechanical properties, appealing appearance, and wide finish options, making it a versatile choice for both residential and commercial projects. Its inherent characteristics necessitate minimal maintenance while providing long-term durability and aesthetic appeal.
