I. Lithology and Physical Properties

1. Rock Texture: Linshu Qing Stone is a natural granite, primarily composed of quartz, feldspar, and a small amount of biotite. The crystal particle size ranges from 0.5 to 3mm, with a dense and uniform structure.
2. Color and Texture: Base color is black gray with black and gray dots scattered on the surface, featuring a simple and elegant texture, rustic tones, suitable for various decorative styles.
3. Physical Properties:

• Compressive Strength: Up to 210MPa, significantly exceeding that of ordinary stone, capable of withstanding high-intensity pressure.
• Flexural strength: 14.2 MPa, excellent bending performance.
• Water Absorption Rate: Only 0.25%, highly resistant to water, not prone to swelling or cracking due to moisture.
• Rockwell hardness: 83HSD, high wear resistance, suitable for high flow areas.
• Corrosion Resistance: High resistance to acids, excellent weathering properties, suitable for long-term outdoor use.
