Aswad Stone is a medium-grained, deep charcoal black basalt quarried in Syria. It is known for its striking dark color and durability, making it a popular choice for both interior and exterior applications. Below is a detailed description of its characteristics, including texture, pattern, test results, chemical and mineral compositions, usage, maintenance, cutting, and surface finish options.
Texture and Pattern
Texture: Medium-grained with a consistent, dense structure. The surface is typically smooth but can have a slightly rough feel due to the natural grain of the basalt.
Pattern: Uniform and homogeneous, with minimal veining or variation. The deep charcoal black color is consistent throughout the stone, giving it a sleek and modern appearance.
Test Results
Aswad Stone is known for its high durability and strength. Typical test results include:
Density: ~2.9–3.1 g/cm³ (high density, contributing to its strength).
Compressive Strength: ~200–300 MPa (excellent for heavy-duty applications).
Water Absorption: ~0.1–0.5% (low porosity, making it resistant to moisture and staining).
Abrasion Resistance: High, suitable for high-traffic areas.
Frost Resistance: Excellent, making it ideal for outdoor use in cold climates.
Chemical and Mineral Composition
Primary Minerals:
Plagioclase feldspar
Pyroxene
Olivine
Magnetite (contributing to the deep black color)
Chemical Composition:
Silicon Dioxide (SiO?): ~45–55%
Aluminum Oxide (Al?O?): ~10–15%
Iron Oxide (Fe?O?): ~10–12% (responsible for the dark color)
Calcium Oxide (CaO): ~8–10%
Magnesium Oxide (MgO): ~5–8%
Minor traces of titanium, potassium, and sodium oxides.
Usage
Aswad Stone is versatile and can be used in a variety of applications:
Interior: Flooring, wall cladding, countertops, fireplace surrounds, and decorative accents.
Exterior: Paving, facades, landscaping, pool surrounds, and monuments.
Commercial: High-traffic areas such as airports, shopping malls, and office buildings.
Architectural: Modern and minimalist designs due to its uniform color and texture.
Maintenance
Cleaning: Use a pH-neutral stone cleaner and avoid acidic or abrasive cleaners that could damage the surface.
Sealing: While Aswad Stone has low porosity, applying a penetrating sealer can enhance its stain resistance, especially in high-use areas.
Stain Removal: Blot spills immediately and use a poultice for stubborn stains.
Regular Care: Sweep or vacuum to remove dirt and debris, and mop with a damp cloth for deeper cleaning.
Cutting and Fabrication
Cutting: Aswad Stone can be cut using diamond-tipped tools due to its hardness. It is suitable for precise cutting and intricate designs.
Fabrication: Can be fabricated into tiles, slabs, blocks, and custom shapes. Its consistency allows for uniform cutting and minimal waste.
Surface Finish Options
Aswad Stone can be finished in various ways to achieve different aesthetic and functional effects:
Polished: High-gloss finish that enhances the deep black color and adds a luxurious look. Ideal for countertops and interior applications.
Honed: Smooth, matte finish that retains the stone’s natural texture. Suitable for flooring and wall cladding.
Bush-Hammered: Textured surface with a rough, anti-slip finish. Perfect for outdoor paving and pool surrounds.
Flamed: Thermally treated surface with a slightly rough texture. Commonly used for exterior applications.
Sandblasted: Matte finish with a subtle texture, providing a softer appearance.
Brushed: Slightly textured surface with a natural, aged look.
Advantages
Durability: Highly resistant to wear, weathering, and impact.
Aesthetic Appeal: Deep black color with a uniform appearance.
Versatility: Suitable for a wide range of applications.
Low Maintenance: Requires minimal upkeep due to its density and resistance to staining.
Conclusion
Aswad Stone is a premium basalt with exceptional durability and a striking deep charcoal black color. Its versatility, low maintenance, and range of finish options make it a popular choice for both residential and commercial projects. Whether used for modern interiors or rugged exteriors, Aswad Stone offers a timeless and elegant aesthetic.
