Rosa Santa Eulalia Granite

Rosa Santa Eulalia Granite is a distinctive and attractive granite variety quarried in Portugal at Mt. dos Frades, Santa Eulália (Elvas), in the Distrito de Portalegre. It exhibits a granular hypidiomorphic texture typical of granite, characterized by medium to coarse grains that interlock to form a robust matrix. This granite's predominant color is rosy-pink to soft red, thanks to abundant potassic feldspar crystals. The presence of medium to coarse biotitic specks, along with lighter quartz components, contributes to its homogeneous, warm, and inviting appearance without dramatic veining.

Physical and Mechanical Properties:

• Water Absorption: 0.16% by weight
• Density: 2635 kg/m³
• Flexural Strength: 20.0 MPa
• Compressive Strength: 167.10 - 170.0 MPa
• Hardness: Generally corresponds to the hardness of the component minerals, with feldspar being 6-6.5, quartz being 7, and biotite around 2.5-3 on the Mohs scale.
• Porosity: Low, typical of quality granite which contributes to its durability and resistance to weathering.
• Slip Resistance: Moderate to high, depending on the finish, making it suitable for a variety of applications, including flooring in both interior and exterior spaces.

Chemical and Mineral Composition (% by weight):

• Quartz: 30%
• Microcline: 35%
• Plagioclase: 25%
• Biotite Mica: 8%
• Others: 2%.

Usage:

• Interior Applications: Kitchen countertops, bathroom vanities, flooring, wall cladding, and decorative purposes.
• Exterior Applications: Facades, paving, monuments, and other architectural elements due to its durability and aesthetic appeal.
