I. Rock and Physical Properties

1. Rock Texture: Linshu Qing Stone is a natural granite, mainly 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 scattered on the surface. The texture is simple and elegant, with a rustic tone, suitable for various decorative styles.
3. Physical Properties:

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