Laizhou Sesame White Granite is a fine-grained, compact granite quarried in Laizhou, Yantai, Shandong Province, China. It is one of the most popular granites in China due to its durability, weather resistance, and uniform appearance. The stone is often used in large-scale construction projects, landscaping, and architectural applications worldwide.

1. Texture, Pattern & Appearance

Base Color: Light gray to off-white.

Pattern: Uniformly distributed black, gray, and white speckles, resembling sesame seeds.

Grain Structure: Fine- to medium-grained, compact, and dense texture.

Luster: Moderate, depending on surface finish (polished, honed, etc.).

2. Test Results & Physical Properties

Property ........Value:

Density........2.63 – 2.75 g/cm³

Water Absorption........≤ 0.3%

Compressive Strength........≥ 150 MPa

Flexural Strength........≥ 12 MPa

Mohs Hardness........6 – 7

Weather Resistance........Excellent

Slip Resistance........High (with flamed or bush-hammered finish)

This data confirms the stone’s high strength, low porosity, and excellent durability, making it suitable for both interior and exterior applications.

3. Chemical & Mineral Composition

Component........Percentage (%):

Quartz (SiO?)........30 – 35

Feldspar........45 – 55

Mica........5 – 10

Iron Oxides........≤ 1

The high feldspar and quartz content gives the granite its strength and hardness, while mica contributes to its slight sheen. The low iron content helps prevent excessive oxidation or rusting.

4. Common Applications

Exterior Applications:

Paving (sidewalks, plazas, streets)

Wall cladding (commercial and residential buildings)

Stair treads and risers

Outdoor benches and monuments

Landscaping elements (fountains, sculptures)

Interior Applications:

Flooring and wall panels

Kitchen countertops and vanity tops

Fireplaces and decorative features

Tabletops and bar counters

5. Cutting & Surface Finish Options

Laizhou Sesame White Granite can be processed into various surface finishes to suit different applications.

Finish Type...........Description........Recommended Use:

1. Polished: Smooth, reflective, and glossy........Indoor flooring, countertops, wall panels
2. Honed: Matte, non-reflective surface........Flooring, walls, staircases
3. Flamed: Rough, textured, and slip-resistant........Outdoor paving, pool decks
4. Bush-Hammered: Coarse, non-slip finish........Public walkways, external walls
5. Sandblasted: Fine-textured surface with a soft, weathered look........Monuments, exterior cladding

Granite blocks from Laizhou can be cut into customized sizes, including slabs, tiles, cubes, and irregular shapes based on project requirements.

6. Maintenance & Care

Daily Cleaning: Use mild soap and water; avoid acidic cleaners.

Sealing: Optional but recommended for polished and honed surfaces to protect against stains.

Stain Removal: Use a pH-neutral stone cleaner; for tough stains, apply a granite poultice.

Long-Term Care: Inspect and reseal outdoor installations every 2-3 years for optimal durability.

7. Conclusion

Laizhou Sesame White Granite is a highly durable, aesthetically appealing, and versatile stone. Its neutral color and fine-grained texture make it an excellent choice for architectural, landscaping, and construction projects. With low maintenance needs, strong physical properties, and multiple surface finishes, it is a preferred material for both commercial and residential applications.
