Rojo Argallon Granite

Rojo Argallon Granite is a distinctive natural stone quarried from the Argallón-Fuente Obejuna region in the Sierra Morena mountains of Cordoba, Andalusia, southern Spain. This granite is well-known for its vibrant deep red to burgundy background, enriched with scattered dark gray to black mineral speckles and occasional subtle gray grains, creating a warm and inviting visual appearance. The medium- to coarse-grained and crystalline texture is formed by the interlocking minerals such as feldspar, quartz, and dark ferromagnesian components, making it not only visually appealing but also durable.

Physical and Mechanical Properties:

• Water Absorption: Low, usually between 0.25% to 0.35%
• Density: Approximately 2.65 to 2.73 g/cm³
• Flexural Strength: Ranges from 15 to 17 MPa
• Compressive Strength: Averages between 140 and 160 MPa
• Hardness: Mohs scale rating of 6-7, indicating good scratch resistance
• Porosity: Generally low, aiding in its durability and resistance to staining
• Slip Resistance: Moderate, varies depending on surface finish

Chemical and Mineral Compositions (% by weight):

• Feldspar: ~50-60%
• Quartz: ~20-30%
• Mica (Biotite/Muscovite): ~5-10%
• Ferromagnesian Minerals: ~5-10%
• Other Trace Minerals: ~1-3%

Usage:

• Interior Applications: Ideal for countertops, flooring, wall cladding, and decorative features due to its striking appearance.
• Exterior Applications: Suitable for facades, exterior pavements, and landscaping elements, given its strength and durability.
• Monumental Uses: Can be used in the creation of monuments or sculptures due to its ability to take fine detailing.

Maintenance:

• Regular cleaning with a mild soap and water solution is recommended.
• Sealant application every 1-2 years to maintain resistance against stains and enhance surface longevity.
• Avoid harsh chemicals or acidic cleaners to prevent dulling the finish.

Available Common Surface Finish Options:

• Polished: Provides a glossy, reflective finish that enhances the color and pattern.
• Honed: Offers a smooth, matte finish for a more subtle appearance.
• Flamed: Produces a textured surface with excellent slip resistance, ideal for external applications.
• Bush-Hammered: Creates a rugged texture, enhancing slip resistance and aesthetic appeal for outdoor use.

Rojo Argallon Granite combines aesthetics and functional durability, making it a popular choice for a range of architectural and decorative applications.
