- Stone texture:
- a fine-grained volcanic stone characterized by a predominantly grey to dark grey color, sometimes shifting toward black or dark brown depending on mineral composition and quarry variation. It presents a generally uniform and consistent appearance, making it highly suitable for large-scale architectural applications, while subtle tonal variations and occasional weathering effects may introduce slight depth and natural character.
Description
Basalt Aramus is a fine-grained volcanic stone famously quarried in Abovian, Armenia, which is approximately 15 km from the capital city, Yerevan. It's predominantly known for its grey to dark grey color, but this can vary to black or dark brown depending on its mineral composition and the particular quarry section. Its uniform appearance makes it ideal for architectural projects, while its natural tonal variations and weathering effects add slight depth and character.
Physical and Mechanical Properties
- Water Absorption: Typically low (around 0.25% - 0.35%)
- Density: Approximately 2.85 - 3.0 g/cm³
- Flexural Strength: Roughly 12 - 14 MPa
- Compressive Strength: Generally, 170 - 190 MPa
- Hardness: Typically 6 - 7 on the Mohs scale
- Porosity: Low, usually less than 1%
- Slip Resistance: Moderate to high, depending on surface finish
Chemical and Mineral Compositions (% by weight)
- Silicon Dioxide (SiO2): 45% - 52%
- Aluminum Oxide (Al2O3): 12% - 17%
- Iron Oxide (Fe2O3): 8% - 12%
- Calcium Oxide (CaO): 6% - 8%
- Magnesium Oxide (MgO): 5% - 7%
- Sodium Oxide (Na2O) and Potassium Oxide (K2O): 3% - 5%
- Trace elements: Include Titanium Dioxide (TiO2), Manganese Oxide (MnO), etc.
Usage
- Architectural Cladding: Owing to its uniformity, it is suitable for large facades and decorative cladding.
- Flooring and Paving: Used extensively in areas that require durable, slip-resistant surfaces.
- Monuments and Sculpture: Its workability allows for intricate designs.
- Interior Applications: Such as countertops, backsplashes, and decorative furniture elements.
Maintenance
- Routine cleaning with neutral pH cleaners.
- Periodic sealing can enhance stain resistance, especially in high-traffic areas.
- Avoid using acidic or abrasive cleaners to prevent surface damage.
Common Surface Finish Options
- Polished: Offers a glossy, reflective surface ideal for interior applications.
- Honed: Provides a smooth, matte finish that is less reflective.
- Bush-Hammered: Textured for increased slip resistance, suitable for outdoor paving.
- Flamed: Rough surface created by exposing to high temperatures, enhancing slip resistance and natural color.
Basalt Aramus is a versatile material, perfectly balancing aesthetics with structural reliability, making it a popular choice for various construction and design purposes. Its ease of maintenance and variety of finishes ensure its suitability for a wide range of both interior and exterior applications.
