I. Rock 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 grain size ranges from 0.5 to 3mm, with a dense and uniform structure.
2. Color and Texture: Base color is dark gray with black and gray dots sprinkled on the surface. The texture is simple and elegant, the tone is rustic, suitable for various decorative styles.
3. Physical Properties:

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