Description:
Yellow Valverde Limestone is a fine- to medium-grained natural stone known for its warm golden beige base that is complemented by lighter hues. It exhibits a unique pattern containing tiny fossil segments, which gives this limestone a distinctive and appealing appearance. Sourced from Pedreira de Azul in Alcanede, Santarém, Portugal, it’s a popular choice for various architectural and design applications due to its aesthetic appeal and robust properties.

Physical and Mechanical Properties:

• Water Absorption: 0.5%
• Density: 2643 kg/m³
• Flexural Strength: 15.0 MPa
• Compressive Strength: 150.2 MPa
• Hardness: Medium, typical for limestone, suitable for indoor flooring and cladding.
• Porosity: Low to medium, contributing to its resistance to weathering.
• Slip Resistance: Moderate, making it safe for most indoor applications but may require additional treatment for high-traffic areas or outdoor use in wet conditions.

Chemical and Mineral Compositions (% by weight):

• Calcium Carbonate (CaCO3): Predominantly high, characteristic of limestone.
• Magnesium Carbonate (MgCO3): Minor presence.
• Silica (SiO2): Present, contributing to its durability.
• Iron Oxide (Fe2O3): Trace amounts, affecting its warm golden hue.
• Aluminum Oxide (Al2O3): Trace amounts.

Usage:

• Interior Applications: Floor tiles, wall cladding, kitchen countertops, bathroom vanity tops, and decorative elements.
• Exterior Applications: Facade cladding, paving, and garden landscaping.
• Architectural Features: Fireplaces, staircases, and window sills.

Maintenance:

• Regular cleaning with a damp cloth and a pH-neutral stone cleaner.
• Periodic sealing recommended to maintain appearance and protect from stains and water infiltration.
• Avoid acidic or abrasive cleaning agents to preserve surface integrity.

Cutting Sizes (cm):

• Standard tile sizes include 30x30, 30x60, 60x60, and custom sizes based on project requirements.
• Slab thickness typically ranges from 2cm to 3cm.

Available Surface Finish Options:

• Polished: Achieves a high gloss, enhancing the stone's color and fossil pattern.
• Honed: Provides a smooth, matte finish suitable for floors and walls.
• Brushed: Offers a slightly textured finish, adding a rustic appeal.
• Bush-Hammered: Features a rough texture, suitable for outdoor and slip-resistant applications.

Overall, Yellow Valverde Limestone is valued for its aesthetic qualities and versatile applications, making it a preferred choice for a variety of residential and commercial projects. Its warm hues and fossilized patterns provide both elegance and natural beauty.
