Description

Shandong Blue Limestone, also known as Bluestone, is a high-quality natural stone known for its consistent dark bluish-silver-gray hue and fine, compact grain structure. It is primarily composed of calcium carbonate and is quarried in Jiaxiang County, Shandong Province, China. This stone is favored for its aesthetic appeal and durability, making it suitable for various architectural and landscape applications.

Physical and Mechanical Properties

  • Water Absorption: Low water absorption rate, typically around 0.3% to 0.4%, making it resistant to water damage.
  • Density: Approximately 2,700 to 2,720 kg/m³, indicating a high density that contributes to its strength and durability.
  • Flexural Strength: Ranges from 11 to 15 MPa, which measures the stone's ability to withstand bending forces.
  • Compressive Strength: Typically between 110 to 140 MPa, showing its capability to bear significant weight and pressure.
  • Hardness: Generally rates around 3 to 4 on the Mohs scale, indicating a moderate hardness suitable for a variety of installations.
  • Porosity: Low porosity due to its compact grain structure, contributing to its durability and resistance to environmental wear.
  • Slip Resistance: Offers good slip resistance, which can be enhanced with surface treatments. Important for outdoor and high-traffic areas.

Chemical and Mineral Composition (% by Weight)

  • Calcium Carbonate (CaCO3): 75-85%
  • Silica (SiO2): 5-10%
  • Alumina (Al2O3): 3-5%
  • Iron Oxide (Fe2O3): 1-3%
  • Magnesium Oxide (MgO): 2-4%

Usage

  • Exterior Applications: Including paving, cladding, and pool coping due to its weather resistance.
  • Interior Applications: Such as flooring, wall tiles, and countertops for its aesthetic appeal.
  • Other Uses: Steps, curbs, and monuments, leveraging its durability and appearance.

Maintenance

  • Regular cleaning with pH-neutral cleaners to maintain its appearance.
  • Periodic sealing to enhance its resistance to stains and moisture penetration, particularly in high-traffic or wet areas.

Cutting Sizes (cm)

  • Common sizes for tiles: 60x60, 30x60, 60x90
  • Custom sizes available upon request for various applications.
  • Thickness can vary depending on usage, typically from 2 cm for tiles up to 5 cm or more for slabs.

Available Surface Finish Options

  • Polished: A glossy finish that highlights the stone's color and patterns.
  • Honed: A matte finish that provides a smooth touch, reducing slip risk.
  • Flamed: A rougher texture for outdoor use, improving slip resistance.
  • Bush Hammered: A textured finish resembling a natural surface for rustic aesthetics.
  • Sandblasted: A slightly textured finish that maintains slip resistance.

Shandong Blue Limestone's combination of physical strength, aesthetic appeal, and versatility in finishes makes it a popular choice for architects and designers in a wide range of projects.

FAQ

Does bleach harm China Blue Limestone terrace pavement?

Yes, bleach can harm China Blue Limestone terrace pavement. Bleach is a harsh chemical that can cause discoloration, etching, and other damage to natural stone surfaces.

Instead, it is best to use a mild soap and water solution or a specialized stone cleaner that is safe for use on natural stone surfaces.

Do I need to seal China Blue Limestone swimming pool copings?

Yes, it is recommended to seal China Blue Limestone swimming pool copings to protect them from water absorption, staining, and weathering. Sealing the copings will also help to enhance their natural color and appearance. Make sure to use a high-quality sealer specifically designed for natural stone materials and follow the manufacturers instructions for proper application.

Does vinegar damage China Blue Limestone countertop?

Yes, vinegar can be damaging to China Blue Limestone countertops. Vinegar is acidic in nature and can etch the surface of the limestone, leading to discoloration and dulling of the finish. It is recommended to avoid using vinegar or any other acidic cleaners on China Blue Limestone countertops and instead use a pH-neutral cleaner specifically designed for natural stone surfaces.

How do I clean China Blue Limestone pool coping?

To clean China Blue Limestone pool coping, you can follow these steps: 1. Start by removing any debris or dirt from the surface of the pool coping using a broom or a brush. 2. Mix a solution of mild detergent or stone cleaner with water in a bucket. 3. Using a soft brush or a sponge, gently scrub the pool coping with the cleaning solution. Make sure to cover the entire surface. 4. Rinse the pool coping thoroughly with water to remove any leftover cleaning solution. 5. For more stubborn stains or dirt, you can use a mixture of water and white vinegar or a specialized limestone cleaner.

Once cleaned, allow the pool coping to dry completely before using the pool again. It is important to avoid using harsh or abrasive cleaners, as they can damage the limestone surface. Regular maintenance and cleaning will help keep your China Blue Limestone pool coping looking its best.

Does China Blue Limestone pool coping get hot under sun?

China Blue Limestone pool coping may get hot under the sun, as most types of stone can absorb and retain heat. It is advisable to test the temperature of the stone before stepping on it with bare feet, especially during hot summer days. Using a splash of water to cool down the stone surface can also help in reducing the heat.

Is polished China Blue Limestone good for pool coping?

This thickness provides the necessary durability and strength for heavy foot traffic while also maintaining a sleek and modern aesthetic. However, the specific thickness may vary depending on the design and structural requirements of the staircase. It is recommended to consult with a professional stone supplier or installer to determine the best thickness for your specific project.

Is China Blue Limestone fire proof?

China Blue Limestone is not completely fireproof. While it is a dense and durable natural stone that can withstand high temperatures, it is not completely resistant to fire. It may be able to withstand some heat without significant damage, but prolonged exposure to high temperatures can cause it to crack or discolor. It is always recommended to use appropriate fire-resistant materials for surfaces that will be exposed to high heat or flames.

Does China Blue Limestone countertop crack under heat?

China Blue Limestone is a natural stone and, like all natural stones, it can be subject to damage under certain conditions. While it is generally heat resistant and can withstand moderate levels of heat, it is still possible for the countertop to crack under extreme heat or sudden changes in temperature. To prevent potential damage to your China Blue Limestone countertop from heat, it is recommended to use trivets or hot pads under hot cookware or dishes to protect the surface. Additionally, avoid exposing the countertop to direct flames or placing hot items directly on the surface to minimize the risk of cracking. Regular maintenance and sealing of the countertop can also help to protect against damage and extend its lifespan.
