Description
Graffiti Marble is a distinguished type of marble quarried in the Lashotor Zone, situated approximately 20 kilometers from the Shiraz road in Esfahan, Iran. Known for its striking appearance, this marble features fine to medium white linear veins that traverse its deep dark grey to greyish-black background, making it an appealing choice for various architectural and decorative applications. Below is a comprehensive overview of its physical, mechanical, chemical properties, and other relevant information.
Physical and Mechanical Properties
- Water Absorption: Typically low, indicating high density and resistance to moisture penetration. Value ranges around 0.2% to 0.34%.
- Density: Approximately 2.7 to 2.73 g/cm³, indicating a relatively high mass per unit volume.
- Flexural Strength: Usually between 12 to 15 MPa, indicating good resistance to bending and flexing.
- Compressive Strength: Typically in the range of 120 to 130 MPa, denoting its ability to withstand substantial loads without being crushed.
- Hardness: Falls around 3 to 4 on the Mohs scale, suggesting moderate scratch resistance.
- Porosity: Generally low, usually less than 1% which helps in reducing staining risks.
- Slip Resistance: Varies with finish; polished surfaces tend to be less slip-resistant compared to honed or textured finishes.
Chemical and Mineral Compositions (% by Weight)
- Calcium Carbonate (CaCO₃): Typically constitutes about 95-98% of the marble.
- Silica (SiO₂): Usually present in small amounts, around 1-3%.
- Magnesium (MgCO₃): Also present in minimal quantities, around 0.5-2%.
- Iron Oxides and other trace elements: Can collectively make up less than 1%.
Usage
- Interior Applications: Suitable for flooring, wall cladding, countertops, and stairs.
- Exterior Applications: Can be used in facades, pathways, and entryways, though proper finishes are necessary for protection against elements.
- Decorative Items: Ideal for sculptures, sinks, and fireplaces due to its aesthetic appeal.
Maintenance
- Regular cleaning with pH-neutral cleaners is recommended to preserve the marble's finish.
- Periodic sealing may be necessary to enhance water and stain resistance.
- Avoid acidic or abrasive cleaners which can etch the surface.
Available Common Surface Finish Options
- Polished: Offers a shiny, reflective surface enhancing color and veining but can be slippery.
- Honed: Provides a smooth but matte finish, reducing slip risk.
- Brushed: Gives a textured feel, often used for slip resistance and a rustic look.
- Sandblasted: Used mainly for exterior applications or decorative wall features for grip and aesthetic textures.
- Leathered: Imparts a more rustic and tactile finish, popular for countertops.
Grafitti Marble from Iran’s Lashotor Zone is a versatile and aesthetically pleasing choice for various architectural and design applications owing to its unique visual characteristics and durable properties. Its maintenance is straightforward, and it can be finished in a variety of ways to meet specific project requirements, ensuring both beauty and functionality.
