Rocheret Gris Limestone is a fine-grained, compact bioclastic limestone known for its natural earthy beige with warm golden beige hues. The stone is accentuated by its yellow tones, golden or gray veins, and speckled or mottled appearance, making it a popular choice for both interior and exterior applications. It is quarried in the regions of Nattages and Aix-les-Bains in France.

Physical and Mechanical Properties:

• Water Absorption: 0.95%
• Density: 2670 kg/m³
• Flexural Strength: 19 MPa
• Compressive Strength: 139 MPa
• Hardness: It has good hardness which contributes to its durability, though specific values might vary.
• Porosity: Generally low, contributing to its durability and moisture resistance.
• Slip Resistance: Varies depending on finish; natural cleft or sandblasted finishes offer higher slip resistance.

Chemical and Mineral Composition (% by Weight):

• The chemical composition primarily includes calcium carbonate (CaCO₃) as the main component.
• It may contain minor amounts of quartz, feldspar, and other minerals typical to limestone, though specific percentages can vary.

Usages:

• Landscaping: Pathways, garden features, retaining walls
• Exterior Cladding: Building facades, exterior walls
• Interior Design: Flooring, wall cladding, countertops, staircases
• Architectural Features: Columns, fireplaces, window sills

Maintenance:

• Regular cleaning with pH-neutral cleaners to avoid damaging the stone.
• Periodic sealing recommended, especially for high-traffic areas, to enhance moisture resistance.
• Avoid acidic or abrasive cleaners that could etch or scratch the surface.

Cutting Sizes (cm):

• Commonly available in large slabs or tiles
• Tiles: Sizes such as 30x30, 40x40, 60x60 are common
• Custom sizes can be fabricated based on project requirements

Surface Finish Options:

• Honed: Smooth, matte finish ideal for interior flooring and wall applications
• Polished: High-gloss finish best suited for interior flooring, countertops, and certain accent pieces
• Brushed: Offers a textured surface, providing a rustic appearance and enhanced slip resistance
• Sandblasted: Textured finish that increases slip resistance, suitable for outdoor paving and cladding
• Bush-hammered: Rough surface finish that creates a rugged feel, often used in exterior applications

This comprehensive overview provides an insight into the properties and applications of Rocheret Gris Limestone, making it a versatile and attractive choice for a variety of architectural and design projects.
