Kemet Granite

Kemet Granite, sourced from Aswan City in Egypt, is renowned for its rich and consistent brown tones. This granite is often sought after for both its aesthetic appeal and its robust physical properties. Here is a detailed overview of Kemet Granite in terms of its physical, mechanical, chemical, and practical characteristics:

Physical and Mechanical Properties

• Water Absorption: Typically around 0.2% to 0.4%. This low absorption rate makes it resistant to moisture and suitable for both interior and exterior applications.

• Density: Approximately 2.67 to 2.71 g/cm³, indicating its substantial weight and mass, which contributes to its durability.

• Flexural Strength: Around 13-15 MPa. This property indicates its ability to withstand bending forces, essential for structural applications.

• Compressive Strength: Typically in the range of 180-220 MPa, showcasing its ability to handle significant pressure without breaking.

• Hardness: Generally around 6-7 on the Mohs scale, reflecting its high resistance to scratches and surface wear.

• Porosity: Very low, often less than 1%, which contributes to its resistance to stains and moisture.

• Slip Resistance: When finished with a flamed or brushed surface, it provides good slip resistance, important for flooring and exterior applications.

Chemical and Mineral Composition (by weight)

• Quartz: 20-30% - Provides the hardness and durability.

• Feldspar: 60-70% - Gives the stone its color and structural integrity.

• Mica: 5-10% - Contributes to the slight sheen and reflective quality.

• Minor minerals and trace elements: Such as iron oxides, which may provide subtle color variations.

Usage

• Interior Applications: Ideal for countertops, floor tiles, and wall cladding due to its rich color and hardness.
• Exterior Applications: Suitable for building facades, pavements, and outdoor monuments because of its resilience to weathering.
• Decorative Purposes: Its uniformity and elegance make it suitable for statues and decorative sculptures.

Maintenance

• Regular Cleaning: Use a neutral-pH cleaner and soft cloths to maintain its appearance.
• Sealing: Although highly resistant, periodic sealing might be encouraged to enhance stain resistance.
• Avoid Abrasives: Strong acids or abrasives should be avoided to prevent potential surface damage.

Cutting Sizes (cm)

• Typically available in large slabs for countertops (e.g., 300 x 160 cm).
• Custom sizes for specific projects, usually range in thickness from 2 to 3 cm.
• Tiles might be pre-cut into common sizes like 30 x 30 cm or 60 x 60 cm for flooring.

Surface Finish Options

• Polished: For a glossy, reflective surface suitable for interiors.
• Honed: For a matte finish ideal for a subtler look on floors or walls.
• Flamed: Provides a rough texture, enhancing slip resistance for outdoor use.
• Brushed: Offers a slightly textured surface, combining aesthetics and functionality.

Kemet Granite's combination of beauty, toughness, and versatility makes it a preferred choice for architects and designers around the globe, particularly for projects needing durable and aesthetically pleasing materials.
