Green Grey Limestone

Green Grey Limestone is a durable and aesthetically appealing natural stone sourced from quarries in Albania, specifically near the town of Berat. This limestone is distinguished by its fine-grain structure and a dark silvery-gray background enhanced subtly with khaki-green shades. Its refined, contemporary aesthetic makes it a popular choice for a range of architectural and design applications.

Physical and Mechanical Properties:

• Water Absorption:Typically low water absorption, indicating good resistance to moisture.

• Density:Approximate density ranges from 2,630 to 2,700 kg/m³.

• Flexural Strength:Generally high, around 10-15 MPa (depending on specific sample testing).

• Compressive Strength:Approximately 110-140 MPa, providing robust structural integrity.

• Hardness:Medium hardness, suitable for various architectural uses.

• Porosity:Low to moderate porosity, which enhances its durability.

• Slip Resistance:Can vary based on finish; typically, honed and polished surfaces may have lower slip resistance compared to other finishes like bush-hammered or sandblasted.

Chemical and Mineral Composition:

• Calcium Carbonate (CaCO3):Predominantly high content, usually above 90%.

• Silica (SiO2):Typically between 1-3%.

• Iron Oxides (Fe2O3):Small percentage contributing to color variations and strength.

• Aluminum Oxide (Al2O3):Present in minor amounts.

• Magnesium Carbonate (MgCO3):Often less than 2%.

Usage:

• Interior Applications: Flooring, wall cladding, staircases, fireplaces, and bathroom settings.
• Exterior Applications: Facades, outdoor flooring, pool copings, and other landscaping uses.
• Commercial and Residential Projects: Suitable for high-traffic areas due to its strength and low porosity.

Maintenance:

• Regular cleaning with pH-neutral detergents.
• Periodic sealing can enhance longevity and appearance.
• Avoid using acidic cleaners that may damage the stone's surface.

Cutting Sizes:

• Standard and custom sizes are available, typically cut in cm.
• Common slab sizes: 60x30 cm, 60x60 cm, and larger custom dimensions based on project needs.
• Thickness generally ranges from 2 cm to 5 cm.

Available Surface Finish Options:

• Honed:Smooth, matte finish ideal for indoor applications where a low-gloss appearance is desired.

• Polished:High-gloss finish that enhances color and veining, commonly used in interior spaces for a luxurious look.

• Bush-Hammered:Textured finish providing slip resistance, suitable for exterior flooring.

• Sandblasted:Slightly textured finish with a matte appearance, suitable for both indoor and outdoor use.

Green Grey Limestone embodies a blend of visual appeal and practical properties, making it a versatile choice for myriad architectural projects. Its natural elegance and durability ensure that it remains a favored option in both commercial and residential settings.
