- a medium- to coarse-grained crystalline composition with tightly interlocking minerals such as quartz, feldspar, and mica, resulting in a dense, compact, and highly durable material; rich and warm natural stone distinguished by its deep brown base color, often complemented by a harmonious blend of black and grey mineral speckles that create a classic, speckled granite appearance. The shade can vary from lighter caramel brown to darker chocolate tones, with the distribution and intensity of speckling ranging from uniform to slightly more pronounced patterns, giving each slab a subtle uniqueness while maintaining overall consistency
Description
Silica Brown Granite is a distinctive and robust natural stone known for its aesthetic appeal and durability. It features a medium- to coarse-grained crystalline structure with tightly interlocking minerals, primarily quartz, feldspar, and mica. Its deep brown base is enriched with black and grey mineral speckles, offering a classic and speckled appearance. The color palette ranges from lighter caramel brown to deeper chocolate hues, with unique patterns in each slab. This granite is sourced from quarries in India.
Physical and Mechanical Properties:
-
Water Absorption: Typically low, around 0.1% - 0.3%, reflecting high density and low porosity.
-
Density: Approximately 2,690 - 2,790 kg/m³, indicating a very compact structure ideal for various applications.
-
Flexural Strength: Usually ranges from 10 - 15 MPa, signifying good resistance to bending forces.
-
Compressive Strength: Around 170 - 200 MPa, providing excellent load-bearing capacity.
-
Hardness: Granite rates around 6-7 on the Mohs scale, implying a high scratch resistance.
-
Porosity: Very low, making it resistant to staining and moisture penetration.
-
Slip Resistance: Generally good, particularly if the surface is honed or flamed, making it suitable for flooring in wet areas.
Chemical and Mineral Composition (% by weight):
-
Quartz: 20% - 30%, providing hardness and resistance to chemicals.
-
Feldspar: 50% - 60%, contributing to the stone's color and mechanical strength.
-
Mica: 5% - 10%, adding to the stone’s lustrous appearance.
-
Other Minerals: 5% - 15%, including biotite and amphibole, enhancing the visual texture.
Usage:
- Countertops: Ideal due to its durability and resistance to heat and scratches.
- Flooring: Appropriate for both interior and exterior, providing an elegant and slip-resistant surface.
- Wall Cladding: Used for its aesthetic appeal and structural integrity.
- Stairs and Steps: Durable with good slip resistance when properly finished.
- Monuments and Memorials: Utilized for its weather-resistant properties.
Maintenance:
- Regular Cleaning: Use mild soap and water; avoid harsh chemicals.
- Sealing: Recommended annually or bi-annually to maintain resistance to stains and moisture.
- Avoiding Excessive Force: Use trivets or coasters to prevent thermal shock or scratches.
Cutting Sizes (cm):
- Standard slabs are typically cut in sizes of 240 x 60, 300 x 60, or similarly customized dimensions based on project requirements.
Common Surface Finish Options:
-
Polished: Offers a glossy, mirror-like surface, enhancing the granite's deep color and pattern.
-
Honed: Provides a smooth, non-reflective surface, suitable for a more subtle aesthetic.
-
Flamed: A rough texture for improved slip resistance, particularly in outdoor applications.
-
Leathered: A softer, textured finish that is non-reflective and pleasant to the touch.
