Renowned for its deep black hue interspersed with subtle flecks of silver, white, and gold, this granite has been a symbol of elegance and durability for centuries.
Geological Formation and Composition
Formed from molten magma under intense heat and pressure, Black Aswan Granite is an igneous rock composed primarily of quartz, feldspar, and mica. These minerals contribute to its unique texture and coloration, as well as its remarkable strength and resistance to wear. The presence of mica and quartz creates the characteristic speckled appearance that enhances its visual appeal.
Physical and Mechanical Properties
Black Aswan Granite is celebrated for its exceptional physical properties:

• Compressive Strength: Approximately 204.08 MPa, indicating its ability to withstand significant loads without crushing.
  
• Flexural Strength: Around 32.41 MPa, reflecting its capacity to resist bending forces.
  
• Density: Approximately 2,854 kg/m³, contributing to its durability and substantial feel.
  
• Water Absorption: Low at 0.03%, making it highly resistant to moisture and staining.
  
• Abrasion Resistance: Rated at 51.9 Ha, showcasing its ability to withstand surface wear.
  

Historical Significance
The use of Black Aswan Granite dates back to ancient Egypt, where it was revered for its strength and beauty. It was extensively used in the construction of temples, obelisks, and statues. Iconic structures such as the obelisks of Karnak and the colossal statues of Ramses II in Luxor bear witness to the ancient Egyptians’ expertise in quarrying and shaping this stone.
Modern Applications
Due to its durability and aesthetic appeal, Black Aswan Granite is utilized in various applications:

• Interior Design: Ideal for kitchen countertops, bathroom vanities, flooring, and wall cladding, offering a sleek and sophisticated look.
  
• Exterior Use: Suitable for facades, paving, and outdoor landscaping, thanks to its resistance to weathering and wear.
