Syrian Basaltic Stone, also known as Aswad Stone Black Basalt, is a premium natural stone quarried in Syria. It is renowned for its deep, rich black color, durability, and versatility. Below is a detailed description of its properties, characteristics, and applications:

1. Texture and Pattern

Color: Deep charcoal black with a consistent, uniform hue.

Texture: Fine-grained and dense, with a smooth, matte finish when unpolished.

Pattern: Minimal veining or patterning, giving it a sleek and modern appearance.

Surface Feel: Smooth to the touch, with a natural, non-porous texture.

2. Technical Test Results

Density: Approximately 2.8–3.0 g/cm³, making it a heavy and durable stone.

Water Absorption: Very low (typically <0.5%), indicating high resistance to moisture and staining.

Compressive Strength: High, ranging between 200–300 MPa, making it suitable for heavy-duty applications.

Flexural Strength: Approximately 20–30 MPa, ensuring it can withstand bending and tensile stress.

Abrasion Resistance: Excellent, making it ideal for high-traffic areas.

Frost Resistance: Highly resistant to freeze-thaw cycles, suitable for outdoor use in cold climates.

3. Chemical and Mineral Composition

Primary Minerals: Composed mainly of plagioclase feldspar, pyroxene, and olivine.

Chemical Composition:

Silicon Dioxide (SiO?): ~45–50%

Aluminum Oxide (Al?O?): ~10–15%

Iron Oxide (Fe?O?): ~10–12%

Calcium Oxide (CaO): ~8–10%

Magnesium Oxide (MgO): ~5–8%

Trace Elements: Titanium, Potassium, and Sodium oxides.

Acid Resistance: Resistant to most acids, but prolonged exposure to strong acids (e.g., hydrochloric acid) may cause slight etching.

4. Usage

Syrian Basaltic Stone is highly versatile and suitable for a wide range of applications, including:

Interior Applications: Flooring, wall cladding, countertops, staircases, and decorative accents.

Exterior Applications: Paving, facades, landscaping, pool surrounds, and outdoor furniture.

Commercial and Public Spaces: Ideal for high-traffic areas such as airports, shopping malls, and hotels due to its durability and low maintenance.

Monuments and Sculptures: Often used for artistic and architectural purposes due to its fine grain and ability to hold intricate details.

5. Maintenance

Cleaning: Use a pH-neutral cleaner and warm water. Avoid harsh chemicals or abrasive cleaners.

Sealing: While the stone is naturally dense and low-porosity, applying a penetrating sealer can enhance its longevity and resistance to staining.

Stain Removal: Address spills immediately. For oil-based stains, use a poultice or specialized stone cleaner.

Polishing: Periodic polishing can restore its natural luster, especially for honed or polished finishes.

6. Cutting and Fabrication

Cutting: Can be cut using diamond-tipped tools due to its hardness.

Fabrication: Suitable for precision cutting, shaping, and carving. It can be fabricated into tiles, slabs, blocks, or custom shapes.

Edge Profiles: Can be customized with various edge treatments, such as straight, beveled, bullnose, or ogee edges.

7. Surface Finish Options

Syrian Basaltic Stone can be finished in various ways to achieve different aesthetic and functional effects:

Polished: High-gloss finish that enhances the stone’s natural color and depth.

Honed: Smooth, matte finish with a soft sheen, ideal for a more understated look.

Bush-Hammered: Textured surface with a rustic, anti-slip finish, suitable for outdoor applications.

Flamed: Thermally treated surface with a rough texture, providing excellent slip resistance.

Sandblasted: Matte finish with a slightly rough texture, often used for decorative purposes.

Brushed: Soft, textured finish that retains the stone’s natural character.

8. Advantages

Durability: Extremely hard and resistant to wear, making it suitable for both indoor and outdoor use.

Aesthetic Appeal: Its deep black color and fine grain make it a popular choice for modern and minimalist designs.

Low Maintenance: Requires minimal upkeep due to its density and resistance to staining.

Versatility: Can be used in a wide range of applications, from construction to decorative arts.

9. Limitations

Cost: Higher cost compared to some other natural stones due to its premium quality and quarrying process.

Weight: Its high density makes it heavier, requiring proper structural support during installation.

Thermal Conductivity: Can feel cold underfoot, which may be a consideration for flooring in certain climates.

Conclusion

Syrian Basaltic Stone (Deep Charcoal Black Basalt) is a premium natural stone prized for its durability, aesthetic appeal, and versatility. Its technical properties, low maintenance requirements, and wide range of finish options make it a top choice for architects, designers, and homeowners seeking a high-quality, long-lasting material. Whether used for interior or exterior applications, this stone adds elegance and sophistication to any project.
