Estremoz Rosa Aurora Marble is a fine-grained marble quarried in the Estremoz, Vila Viçosa, and Évora regions of Portugal. It is renowned for its subtle pink to ivory cream background adorned with soft pastel-colored veins. Below is a comprehensive description of its physical and mechanical properties, chemical and mineral compositions, typical usages, maintenance guidelines, common cutting sizes, and available surface finish options.

Physical and Mechanical Properties:

• Water Absorption: 0.06% by weight
• Density: 2717 kg/m³
• Flexural Strength: 15.1 - 17.6 MPa
• Compressive Strength: 72.6 - 93.20 MPa
• Hardness: Comparable to the Mohs scale rating of 3, typical for marble
• Porosity: Low
• Slip Resistance: Generally low in polished form, better in honed or textured finishes

Chemical and Mineral Composition:

• Calcium Carbonate (CaCO₃): Around 90-95%
• MgO, Fe₂O₃, SiO₂, Al₂O₃: Trace amounts contributing to the color and pattern variations
• Accessory Minerals: Includes dolomite, quartz, micas, and various oxides

Usage:

Interior Applications:

• Flooring
• Wall cladding
• Countertops
• Architectural features such as columns and moldings

Exterior Applications:

• Facades and exterior wall cladding (requires proper sealing and maintenance)

Maintenance:

• Regular Cleaning: Use a pH-neutral cleaner suitable for natural stone.
• Sealing: Regularly seal to protect against staining and moisture absorption.
• Avoid Abrasives: Use non-abrasive pads to prevent surface scratches.

Cutting Sizes:

• Commonly available in standard tile sizes such as 30x30 cm, 30x60 cm, 60x60 cm, and custom slabs
• Thickness typically ranges from 1.2 cm to 3.0 cm

Common Surface Finish Options:

• Polished: High gloss, enhances color and veins, but has lower slip resistance
• Honed: Smooth and matte, provides a softer look with better slip resistance
• Brushed or Antique: Gives a textured, aged appearance
• Sandblasted: Adds a rough texture for increased grip
• Bush-hammered: Provides a rugged, pitted finish

Estremoz Rosa Aurora Marble is celebrated for its aesthetic appeal and versatility, making it a favored choice for both residential and commercial projects. Proper maintenance extends its beauty and functional life, while its various surface finishes and cutting sizes allow for a wide range of design possibilities.
