Apple Grey Sandstone is a fine-grained, dark grey, compact, hard quartzitic stone quarried in China. Known for its aesthetic appeal and durability, this sandstone is suitable for various architectural and construction applications. Below is a detailed description of its properties and relevant information:

Physical and Mechanical Properties:

• Color:Predominantly dark grey.

• Water Absorption:Ranges between 0.50% to 0.80% by weight.

• Density:Falls within 2500–2650 kg/m³.

• Flexural Strength:Generally high, offering robust structural capabilities (exact values may require specific testing).

• Compressive Strength:Ranges between 95.6 – 108.4 MPa, indicating strong load-bearing capacity.

• Hardness:Known for its hardness, contributing to its durability (exact Mohs scale value may vary).

• Porosity:Low porosity due to its compact nature, contributing to its low water absorption.

• Slip Resistance:Offers good slip resistance, making it suitable for flooring and outdoor applications.

Chemical and Mineral Composition:

• SiO₂ (Silicon Dioxide): High percentage due to quartz content.
• Al₂O₃ (Aluminum Oxide): Present in lesser amounts.
• Fe₂O₃ (Iron Oxide): Small percentages contributing to color variations.
• Other minerals and compounds: Trace amounts of various minerals that influence its aesthetic and physical properties.

Usage:

Construction & Architectural Applications:

• Exterior and interior wall cladding.
• Flooring for both indoor and outdoor settings.
• Landscaping elements such as pavers and garden features.
• Steps, risers, and other structural components.

Decorative Uses:

• Countertops and backsplashes.
• Decorative panels and feature walls.

Maintenance:

• Regular cleaning with a mild detergent and water.
• Sealing may be recommended to reduce staining and to enhance longevity.
• Avoid acidic or abrasive cleaners that can damage the surface.

Cutting Sizes:

• Commonly available in variable sizes to accommodate different architectural needs.
• Customized cut sizes can be arranged depending on project specifications.

Surface Finish Options:

• Polished:Smooth, shiny surface enhancing color and pattern; suitable for indoor use.

• Honed:Smooth but matte finish; maintains slip resistance, ideal for flooring.

• Sandblasted:Rougher texture; good for outdoor and high-traffic areas.

• Bush-hammered:Highly textured surface; excellent slip resistance for exterior applications.

• Flamed:Rugged surface achieved by thermal treatment, enhancing aesthetics and slip resistance.

Each of these options provides unique aesthetic and functional benefits, making Apple Grey Sandstone a versatile choice for many design requirements.
